Abstract

The embodiment of the invention provides a shale gas quantitative evaluation method, device and equipment based on tectonic deformation strength. The method comprises the steps of determining parameters, reflecting the tectonic deformation strength, of a target research area; constructing a deformation strength index according to the parameters; and according to the deformation strength index, carrying out shale gas step-by-step evaluation zoning on the target research area. According to the embodiment of the invention, quantitative evaluation of the reservoir favorable zone of the shale oil and gas area can be realized.

Description

technical field [0001] This specification relates to the technical field of unconventional oil and gas exploration and development, in particular to a method, device and equipment for quantitative evaluation of shale gas based on structural deformation strength. Background technique [0002] Marine organic-rich shale is generally developed in southern my country, and the plane distribution of original quality such as thickness, mineral composition and organic carbon content of shale is stable. However, there are many stages of structural deformation and high deformation intensity. After multiple stages of structural transformation, the enrichment of shale gas differs significantly, making the exploration and development of shale gas difficult. [0003] The inventors of the present application found that the difference in plane gas-bearing properties of shale gas mainly depends on the preservation conditions affected by structural deformation. Therefore, the quantitative eval...
