摘要
Abstract
In data processing and interpretation with the three-water model in the Fuyang reservoir of Chaochang D district, accurate reservoir shale content is the basis for accurately calculating other physical property parameters. Introduced is the porosity differential value calculated by the fine particle composition of sensitive neutron-density cross-plot method, and established are the direct quantitative relationships between the porosity differential and the shale content. With the natural gamma ray method commonly used in production practice to calculate the formation shale content and natural gamma ray relative value Jgr as the dynamic parameter, we try to dynamically calculate the shale content with the gamma method and neutron-density logging method, which means we not only depend on a certain logging method in shale content calculation, and at the same time we retained the advantages of single well logging methods. Using the same logging and core data, we have calculated the shale content separately by the three methods such as natural gamma method, neutron -density method and gamma + neutron - density combining method. The shale content calculated by the optimized log curve combining method has higher precision, which can meet the requirement of practical log application.关键词
