In September 2011, the research group of "investigation and Research on the implementation of the new geological prospecting mechanism" went to Daqing Oilfield for investigation. After discussion with oilfield leaders, experts and employees, on-the-spot investigation and visit, the research group had a comprehensive understanding of the development and reform of Daqing Oilfield and its contribution to the country, management system, operation mechanism, scientific and technological innovation, and wrote a research report

The main part of Daqing Oilfield is located in the northeast of Songliao plain and the Songnen Plain in the west of Heilongjiang Province, including Daqing placanticline and its periphery. The development process of Daqing oilfield can be divided into seven stages. That is:

early development period (1960-1963)

rapid rising stage (1964-1975)

the first ten-year stable proction stage (1976-1985)

the second ten-year stable proction stage (1986-1995)

continuous stable proction stage (1996-2002)

sustainable and effective development stage (2003-2008)

high and stable yield stage (after 2009)

At present, to achieve the goal of high and stable proction, we are faced with three challenges: resource replacement, technology bottleneck and return on investment. Therefore, Daqing Oilfield deeply studies and practices the scientific development concept, highlights the main line of changing the development mode, takes the concept renewal as the guide, takes the scientific and technological innovation as the support, and takes the typical demonstration as the guide, and makes a major strategic adjustment to the oilfield exploration and development. This strategy puts forward a sustainable and brilliant goal for oilfield exploration and development in the new era. It is required to focus on the development of oil and gas exploration and development business to ensure the continuous high and stable proction of crude oil, and use the stable proction of crude oil to drive the development of related business. Its strategic layout is to consolidate Songliao, speed up the development of new areas, stabilize oil and gas, and develop overseas

Daqing Oilfield is a large enterprise group which combines exploration and proction. In this group, geological prospecting and prospecting are very important parts. It not only determines the prosperity and development of the oilfield, but also determines the scale and speed of the oilfield. It can be said that the key to high and stable proction of Daqing Oilfield is to provide oil and gas resources for proction. The framework of exploration system is as follows:

investigation and Study on the implementation of new geological prospecting mechanism. From this framework, we can see that: (1) the exploration system of Daqing Oilfield is not only the exploration department, but also the reservoir evaluation department. They are all functional departments directly under Daqing Oilfield, which jointly undertake the management, coordination, supervision and assessment of oilfield exploration, and restrict each other; ② Under the exploration department, it is not only the exploration branch that undertakes the proction of engineering means, but also the oil field exploration and Development Research Institute. The two cooperate with each other through the contract relationship to combine proction and scientific research; ③ Under the reservoir evaluation department, not only the oil proction plants responsible for oil and gas proction, but also the oil field exploration and development research institutes cooperate with each other to combine proction and scientific research through contracts; ④ There is a combination of exploration and proction between exploration companies and oil proction plants, and there are many professional technical service companies supporting their combination, all of which are enterprises. In this system, the key connection points of exploration proction combination are two aspects:

1. Oilfield proction process connection

the so-called proction process refers to the formation process of oilfield proction capacity, which mainly includes four stages. The first stage is prospecting and exploration to form oil and gas resources for development and utilization. This resource is particularly important for resource-based enterprises. It is the material basis and the source of procts. It directly determines the survival and development of enterprises, as well as the scale and efficiency. The second stage is oilfield construction, which is to develop oil and gas from underground. It needs a series of infrastructure construction. It is obviously based on the results of the first stage. The third stage is oil and gas proction, that is, transferring oil and gas from underground to surface, and turning them into mineral procts that can be used by society. It is obviously conditional on the previous two stages. The fourth stage is oil and gas sales, that is, the oil and gas output is sold or transferred to deep processing (instrial chain extension), oil and gas from the physical form into money, completing a big cycle. This is the whole process of oil and gas proction. The proction process, professional personnel and technical equipment required for this process (the four stages) are different, so they are all separated in system, but the connection mode can be divided into in system and out of system. Daqing belongs to the combination of exploration and proction in the system, and there is no need to go through the market or exchange equivalently. This connection is the most compact, no gap, completely integrated

The so-called cost-benefit connection refers to the four stages of oil and gas proction, which are connected together through their respective costs to form the total cost. Oil and gas sales revenue minus the total cost is the overall benefit of oil and gas proction, or "gross profit". Gross profit is not distributed in the four stages, but it is created by the four stages. The total cost of oil and gas procts is equal to the rights and interests of the mining area + exploration cost + proction cost + proction and operation cost + period expenses (including sales cost). The rights and interests of mining area refer to the rent of mining right and occupied land. These costs and expenses are independent and interchangeable. Mutual independence means that the share allocated in each stage of the overall budget is strictly limited and cannot be overspended; Interchangeability means that under the principle of not breaking through the total cost, the economic value of proved reserves can be determined by the combination of high-cost exploration cost and low-cost mining cost, or vice versa. This cost-benefit connection makes both exploration and mining concerned about the total cost and overall benefit of oil and gas, forming a community of interests. Overspending or failing to meet the requirements at a certain stage will not only affect their own interests, but also the overall interests and long-term interests. Its interest chain runs through the whole process of oil and gas proction, while the interest chain of separation of exploration and proction is only until the transfer of exploration results; The interest chain of engineering means is up to the engineering stage

Second, the exploration and development goal of Daqing Oilfield in the new period is a long-term continuous process, which must be based on the development strategy

1) the outline of sustainable development of Daqing Oilfield defines three strategic tasks of Daqing:

the original sustainable and stable proction

overall coordinated development

build a harmonious mining area

exploration should bear the brunt of the crisis, and take on the important task of providing backup resources for the sustained and stable proction of crude oil in the oilfield. Therefore, the sustainable and brilliant goals of Daqing Oilfield are put forward as follows: 1) to build a century old oilfield with the largest proven resource ratio, the highest oil recovery ratio, stable proction by stages, and always maintaining an important position in the national energy layout. ② The development orientation of oil and gas exploration business in the outline of sustainable development of Daqing Oilfield is to focus on the development of oil and gas exploration and development business, ensure the continuous and stable proction of crude oil, and drive the development of related business with the stable proction of crude oil

The exploration and development strategy is to consolidate Songliao, speed up the development of new areas, stabilize oil and gas proction, and develop overseas

The general requirements for exploration are as follows:

more high-quality reserves

the exploration progress is faster

The total amount of

is larger

the cost of discovery should be lower

The overall exploration deployment principles are as follows:

based on placanticline, strengthen deep layer, refine Haita, expand Sanzhao, prepare Xipo, develop overseas, explore periphery, and study unconventional (among them, "Changyuan", "Haita", "Sanzhao" and "Xipo" are the names of oilfield blocks)

although the above strategic objectives are simple in words, they are all very specific. There is no empty talk or big talk, which reflects the practicability of enterprise strategy

The outline of sustainable development of Daqing Oilfield also points out the "five challenges" faced by oilfield development: first, resource replacement. The annual oil and gas reserves submitted by the oilfield can not meet the needs of stable crude oil proction and natural gas proction. It is difficult and heavy to achieve orderly replacement of reserves and basic balance between storage and proction

The exploration of Daqing Oilfield has been carried out for many years, and the newly proved recoverable oil reserves have increased year by year, but the proction has increased faster, and the imbalance between reserves and proction is very significant. Therefore, there are many problems that restrict the development of exploration in Daqing Oilfield, which must be solved: the remaining resources are highly hidden and difficult to be discovered

The resource grade is low and it is difficult to optimize

the reserve areas are insufficient and it is more difficult to replace them

The cost of exploration is increasing, and the cost control is becoming more difficult

To solve these problems is also the strategic goal of Daqing oilfield exploration

In the face of the new situation, in order to achieve the exploration and development goals, the exploration and development mode needs to achieve four changes:

1. Adjust the exploration ideas, highlight the reserves (reserves that can be developed and utilized at any time), and realize the transformation of the work focus from "all around indicators" to "all around benefits", The next exploration target is divided into three levels:

the first level is the evaluation exploration target, which means that the geological conditions and hydrocarbon accumulation rules have been basically understood, the exploration methods have been basically clear, and there are economic and effective recoverable reserves that can be optimized in a certain scale. It is necessary to speed up the evaluation of such areas and submit reserves as soon as possible

the second level is to get rid of the pre exploration target, which means that the basic law has not been clearly understood, and the exploration focus is mainly on basin evaluation or zone evaluation, and the focus is on understanding the geological law. It is necessary to strengthen the comprehensive study of geology, drill a well, study a well, and control the rhythm

The third level is the reserve exploration field, which refers to the field that has a certain understanding of the large geological conditions and proves that it is difficult to effectively explore and develop under the current economic and technological conditions. It is necessary to strengthen the study of geological laws and engineering technology, seek effective exploration and development methods, and prepare for the future

The project manager responsibility system emphasizes that the project manager is the first person in charge of the exploration project and the organizer and manager of exploration deployment and proction operation. Implementing the responsibility system of exploration project manager and clarifying the responsibilities, rights and interests of project manager is an important link to strengthen exploration project management and improve exploration efficiency

in the decision-making of exploration deployment and proction organization, the exploration project manager should not only consider the effectiveness of technology, but also pay attention to the economic feasibility, so as to realize the transformation of management mode from "proction technology management" to "proction and operation management"

In accordance with the general principle of "pre exploration focuses on discovery, evaluation focuses on implementation, and proctivity needs are taken into account", joint deployment of pre exploration and evaluation, overall optimization of workload, and efforts to improve the degree of reserves utilization, And effectively shorten the proction cycle from pre exploration to completion

Expand the exploration field, implement comprehensive exploration, and realize the transformation of management idea from "single oil and gas exploration" to "comprehensive exploration of multiple resources with oil and gas as the main body"

this transformation not only improves the overall benefit of Daqing Oilfield, but also makes comprehensive utilization of national mineral resources, and is of great benefit to environmental protection and coordinated development
