Embodiment Construction

[0058] In order to make the above and other objects, features and advantages of the present invention more comprehensible, the preferred embodiments are listed below and shown in the accompanying drawings in detail as follows.

[0059] like figure 1 as shown, figure 1 It is a flow chart of the evaluation unit preservation coefficient weight quantitative assignment method in the shale oil resource calculation of the present invention.

[0060] 1) Evaluation unit division: According to the actual geological structure and preservation conditions of the study area, different evaluation units are divided; for the division of evaluation units, firstly, fine interpretation of the structure of the study area is carried out, and the distribution characteristics of the target layer and the distribution characteristics of the main faults are clarified. Layer overlap or pinch-out distribution, boundary faults as the boundary conditions, combined with the analysis of the buried depth of t...

Abstract

The invention provides an evaluation unit storage coefficient weight quantitative assignment method during shale oil resource quality calculation. The method comprises the steps that step 1, differentevaluation units are divided according to the actual geological structure and storage condition characteristics of a study area; step 2, a typical well drilling or outcrop section is selected; step 3, a relationship chart between organic matter abundance and oil content parameters of the different evaluation units and different lithologic lithofacies is established; step 4, storage coefficient weight assignment quantitative models for the different evaluation units and different lithofacies are established; and step 5, resources qualities are calculated for different evaluation units and lithofacies types. The evaluation unit storage coefficient weight quantitative assignment method during shale oil resource quality calculation is more scientific, results are more objective, the problem of inaccurate evaluation of the shale oil resource quality in reformed basins is solved, and technology support for actual exploration operation of shale oil can be provided.

Description

technical field [0001] The invention relates to the technical field of oil field development, in particular to a method for quantitatively assigning weights of evaluation unit preservation coefficients in the calculation of shale oil resources. Background technique [0002] In recent years, the exploration and development of shale oil and gas have achieved great success in North America, which has promoted the upsurge of global shale oil and gas exploration research, and the exploration of shale oil and unconventional oil and gas resources has attracted more and more attention. Global shale oil and gas research is still in its infancy. In the early stage of oil and gas exploration, the evaluation of shale oil resources is of great significance for the selection of shale oil and gas exploration direction and play evaluation. Regarding the evaluation of conventional resources, predecessors proposed a variety of research methods such as analogy method, statistical method, gene...
