Document Type and Number:
WIPO Patent Application WO/2024/087867
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of tectonic fissures in oil exploration. Provided are a characterization method for the in-situ openability of a deep tectonic fissure, and a storage medium. The method comprises: selecting and preparing a plunger sample, and determining the bridging development situation of a fissure filling material in the plunger sample; if the fissure filling material of the plunger sample has a bridging situation, determining the type of a bridging mineral of the fissure filling material; calculating a fissure filling material growth index on the basis of the type of the bridging mineral of the fissure filling material; and on the basis of a static fissure opening degree and the fissure filling material growth index, analyzing a fissure opening history, and determining an in-situ fissure opening degree. The present method not only solves the problems of the uncertainty and the multiplicity of solutions of a comprehensive geological analysis method and an inclusion homogenization temperature method, but also solves the problem of fissure opening degree determination within a specific geological burying period; moreover, a calculation method for a deep in-situ fissure opening degree is further established, and the influence of the growth of a fissure filling mineral on a fissure opening degree under a deep-burying condition is quantitatively evaluated.
