复杂断裂综合解释方法在长昌凹陷的应用
Application of comprehensive interpretation method for complicated fractures in Changchang Sag
摘要
Abstract
The fracture system of Changchang Sag is complicated and dense and the faults have similar occurrence in profile.There is difficulty in interpretation and the relationship among planar connections is unclear.Conventional seismic interpretation is inclined to create confusion, reduce explanation efficiency and lead to difficulties for the fault planar combination, which seriously affects the study of structural traps and hydrocarbon migration.Using coherence technology to target these existing problems, four techniques are applied comprehensively for fine fracture interpretation in the study area.Specific practices include the following are:applying time coherent slices and profiles to explain the faults jointly, using coherent slices along the layer to guide the fault assemblage on planar, using the quantitative statistics of fault displacement to check the fault connection relationship and using 3D visualization technology to verify the spatial combination of faults.The practical application results show that the comprehensive interpretation method based on coherence technology can overcome the shortcomings of conventional interpretation and greatly improve the efficiency and accuracy of complicated fracture interpretation.关键词
