Description

Technical Field

[0001] The present invention relates to the technical field of oil and gas exploration and development, and in particular to a method for evaluating the mobility of offshore oil and gas potential resources driven by development needs. Background Art

[0002] The potential amount of offshore oil and gas resources represents the exploration and development potential of offshore oil and gas fields. The evaluation of their development feasibility is of great significance for optimizing exploration and development deployment and refining production planning.

[0003] Offshore oil and gas exploration and development are very different from onshore ones. The key point is that in addition to considering the quality of the resources themselves and other conditions, the development of most offshore oil and gas fields also needs to consider the conditions of existing key facilities such as offshore processing platforms and oil and gas pipelines. Therefore, the time period from the discovery of a new oil field to its development is largely controlled by background conditions such as the development support.

[0004] At present, domestic oil companies generally focus on their own oil and gas reservoir conditions when evaluating and analyzing potential resources. The conventional practice is to evaluate the reliability or risk level of potential resources by qualitatively analyzing the risks and reliability of the six reservoir elements of generation, storage, capping, transportation, enclosure, and protection, combined with semi-quantitative evaluation methods such as linear weighting. Since conventional practices generally focus on the reservoir conditions of potential resources and do not fully consider the needs of integrated exploration and development, some newly discovered targets are far away from existing offshore facilities and cannot be developed and mobilized as soon as possible, extending the development and production cycle; in addition, conventional practices make it difficult to coordinate the overall situation of discovered oil and gas fields and potential resources to be explored and evaluated, and cannot achieve forward-looking planning and deployment of key engineering facilities from the source of exploration, slowing down the pace of overall resource transformation. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a method for evaluating the mobility of offshore oil and gas potential resources driven by development needs, aiming to solve the problem that the evaluation of potential resources in the related technology only focuses on oil and gas accumulation conditions, while ignoring the evaluation of exploration and development and overall coordination.

[0010] Determine the overall coordination condition coefficient of the potential offshore oil and gas resources, the overall coordination condition coefficient has a value range of 0 to 1, and the overall coordination condition coefficient is positively correlated with the overall coordination condition;

[0011] Taking the geological reliability coefficient, the quality coefficient, the development support condition coefficient and the overall coordination condition coefficient as the criterion layer, and all targets and potential resources as the program layer, the analytic hierarchy process is used to quantitatively evaluate the mobility of all potential resources.

By applying this method, it is possible to speed up the consideration of exploration and development needs, evaluate its comprehensive quality, and provide a strong reference for the forward-looking planning and deployment of key engineering facilities starting from the source of exploration.

[0036] Combine the following Figure 1 The present invention describes a method for evaluating the mobilization of offshore oil and gas potential resources driven by development needs.

[0037] An embodiment of the present invention provides a method for evaluating the mobility of offshore oil and gas potential resources driven by development demand, the method comprising the following steps:

[0038] Step S100: Determine the geological reliability coefficient of the offshore potential oil and gas resources based on the reliability of the reservoir-forming elements of the offshore potential oil and gas resources. The geological reliability coefficient ranges from 0 to 1, and the geological reliability coefficient is positively correlated with the geological reliability.

[0039] Specifically, the reliability of the six reservoir-forming elements of offshore oil and gas potential resources, namely, source layer, reservoir, cap rock, migration, closure and preservation, is qualitatively and semi-quantitatively evaluated, and specific values ​​ranging from 0 to 1 are given according to the reliability of each reservoir-forming element. The higher the reliability, the larger the value. The geological reliability coefficient is obtained by multiplying multiple factors or other mathematical methods.

[0040] Step S200, analogy is performed with surrounding drilled oil and gas fields or oil-bearing structures, and a quality coefficient of offshore potential oil and gas resources is determined based on the analogy result. The value range of the quality coefficient is 0 to 1, and the quality coefficient is positively correlated with the quality of the offshore potential oil and gas resources.

[0041] Specifically, the quality parameters of oil and gas resources, such as physical properties and fluid properties, have a great impact on the difficulty of development. Since the potential resources have not been confirmed by drilling, their quality needs to be compared with the surrounding drilled oil and gas fields or oil and gas structures. Specific analogy parameters include: crude oil viscosity, reservoir porosity, reservoir permeability, etc. The favorable degree of each parameter is given a specific value in the range of 0 to 1. The higher the favorable degree, the larger the value, and the quality coefficient of the potential resources is obtained by multiplying multiple factors or other mathematical methods.

[0042] Step S300: Determine the development support condition coefficient of the potential offshore oil and gas resources based on the parameters of the existing oil and gas processing platform. The development support condition coefficient has a value range of 0 to 1, and is positively correlated with the superiority of the support condition.

[0043] Specifically, the distance between the offshore oil and gas trap and the existing oil and gas processing platform, the oil and gas pipeline capacity and the existing facility margin are comprehensively considered to evaluate the supporting conditions for trap development. The closer the distance, the greater the pipeline capacity and the greater the facility margin, the better the supporting conditions, and vice versa. Based on the comprehensive evaluation of supporting conditions, the supporting condition coefficient is scored, with a score between 0 and 1, which is the development supporting condition coefficient.

[0044] Step S400, determine the overall coordination condition coefficient of the potential offshore oil and gas resources, the overall coordination condition coefficient has a value range of 0 to 1, and the overall coordination condition coefficient is positively correlated with the overall coordination condition.

[0045] Specifically, the overall coordination conditions of offshore oil and gas potential resources represent the foresight and leadership of favorable targets for offshore oil field exploration and development, which is reflected in two aspects: first, the potential resources of favorable targets are large in scale and good in quality, which will most likely drive the construction of key offshore engineering facilities such as surrounding oil and gas pipelines and processing facilities, thereby accelerating oil and gas exploration and development in the entire region; second, favorable targets belong to brand-new exploration areas in the region. If there is a breakthrough, it will open up a new situation in marine exploration and have a high degree of leadership.

[0046] Taking into account the foresight and leading value of potential resources, the overall coordination conditions are scored with a score ranging from 0 to 1, which is the overall coordination condition coefficient.

[0047] Step S500: With the geological reliability coefficient, quality coefficient, development support condition coefficient and overall coordination condition coefficient as the criterion layer, and all targets and potential resources as the program layer, the analytic hierarchy process is used to quantitatively evaluate the mobility of all potential resources.

[0048] Specifically, the geological reliability coefficient, quality coefficient, supporting condition coefficient and overall coordination coefficient obtained in steps S100 to S400 are normalized and used as the criterion layer of hierarchical analysis. All targets and potential resources are used as the scheme layer to carry out hierarchical analysis and obtain a comprehensive evaluation score for the mobility of all potential resources.

[0049] The development demand-driven offshore oil and gas potential resource mobility evaluation method disclosed in the present invention not only takes into account the geological reliability of the potential resources, but also fully considers factors such as internal resource quality, external supporting conditions, and overall coordination conditions that affect development and production, and takes into account exploration and development needs. By applying this method, it is possible to speed up the consideration of exploration and development needs, evaluate its comprehensive quality, and provide a strong reference for the forward-looking planning and deployment of key engineering facilities starting from the source of exploration.

[0053] Step S300: Determine the development support condition coefficient of the potential offshore oil and gas resources based on the parameters of the existing oil and gas processing platform.

[0054] Step S400, determine the overall coordination condition coefficient of the potential offshore oil and gas resources, the overall coordination condition coefficient has a value range of 0 to 1, and the overall coordination condition coefficient is positively correlated with the overall coordination condition.
