摘要

The authors think that the compact reservoir fracture in T3-J Formation in the north of the Chuxiong basin are mainly the tectonic fractures controlled by local structures based on the results of field fracture survey, description of bore core and identification of well logging. Combined with the conclusion of experiments, they point out that the porosity of rocks, dynamic characters, thickness of single sand in strata and distortional stress field intensity are the main geological factors that control the fracture shaped. Grounded on the geological situation, the authors choose the reversal development of stress field and main curvity of structure distortion to predict the structure growing belt, and then, integrate the two methods to evaluate the developing regions of fractures.
