摘要

Because of the strong tectonic movement during the formation of a limestone buried hill in the A sag, lots of fractures occurred. This paper calculates the strain magnitude of buried hill formations resulting from every tectonic movement using strain analysis methods such as the inversion and forward modeling of structural evolution history of formations, predicts the 3-D fracture network formed in every tectonic movement from the geological genesis standpoint, and therefore, distinguishes the early filled fractures formed in the period of the buried hill formation from the unfilled fractures formed later, achieving the goal of predicting fracture reservoirs in the limestone buried hill.
