Evaluation of Fracture Distribution in Yan′an Jurassic Formation of Mahuangshan Ordos Basin
摘要
Abstract
Yan′an Formation in reservoirs of Jurassic System is low porosity and low permeability in Mahuangshan area,Ordos Basin.The distribution of fracture is significant for evaluating hydrocarbon migration and accumulation and oil or gas development.The main genetic type is defined as structural fracture through field surveys and drilling core description.The fracture is evaluated through tectonic principal curvature method,plate buckling stress field inversion and filter structure methods.Based on the above,comprehensive evaluation factor of fracture is constructed.The match rate between preceding three singlet evaluation methods and log explanation is 50%-65%,while comprehensive evaluation factor of fracture used come to 85%,thus the accuracy of fracture distribution evalution is obviously improved.关键词
