Abstract

Abstract:

The proximity coefficient of destructiveness of rock in the bottom layer of Shaximiao reservoir can be calculated basing on numerical simulation of the palaeotectonic stress field in Gongshamiao structure and the theory of rock strength. This coefficient and the productive materiel of oil wells have been comparatively analyzed, then the threshold level of the coefficient and
the corresponding grade of the fracture development have been confirmed. Appling this standardization and the theory of lithomechanics and structural geology, combining the observation about fracture in the field and the productive materiel etc.,a comprehensive analysis and prediction of the developmental situation of fracture in the bottom layer of Shaximiao reservoir
have been made.

Key words: fracture, proximity coefficient of destructiveness, developmental situation, prediction
