Embodiment Construction
[0036] Aiming at the limitations of prior art research in this area, the present invention mainly considers the following issues: (1) For the storage body, the reservoir and the caprock have different functions, the reservoir is used to store gas, and the caprock is used to block Gas escapes upward, so the two are equally important; (2) What are the internal causes and controlling factors that cause the different properties of reservoir and caprock and the difference in sealing performance; (3) Unilateral geological Information is difficult to fully reflect the storage capacity of geological bodies, how to effectively and rationally use geological evaluation marks and logging response characteristics to establish a comprehensive evaluation system for storage bodies; (4) the introduction of multiple geological evaluation marks and multiple logging response curves, It will inevitably bring more errors. How to reduce this artificial error and improve the accuracy of evaluation st...
