[Abstract]:The Shanxi formation of Upper Paleozoic in Yanchang District has a wide distribution range and developed reservoir. The result of gas test and production test shows that the gas production rate is higher, which is the main gas producing zone of Upper Paleozoic. In order to accurately evaluate the natural gas resources of Shanxi formation, it is necessary to recognize the gas formation clearly. In this paper, based on the results of logging, experimental analysis and gas test and production, taking the gas formation of Shanxi formation as the object and taking the study of "four-sex relationship" as the key point, and on the basis of comprehensive geological research, this paper closely combines the exploration and development practice of gas fields. The formation mechanism of gas reservoir is deeply studied, and the methods and standards of gas reservoir identification and evaluation are discussed. The results show that Shanxi formation is delta front subfacies and gas layer is mainly developed in underwater distributary channel and estuarine bar sand body. As a result of strong diagenesis for many periods, the gas layer is characterized by various forms and complex formation mechanism. The upper limit of "low resistivity" in this area is determined to be 40? mm, which includes both conventional high resistivity gas formation and "low resistivity" gas. Conventional high resistivity gas reservoirs are mainly controlled by assemblages of generation, reservoir and cap, while the formation of "low resistivity" gas reservoirs is caused by the lithologic fine grains, complex pore structure, high salinity water and high bound water content. The method of log curve overlap, cross plot and array induction logging are used to identify gas reservoir qualitatively, and a logging interpretation model is established for quantitative identification, and a set of criteria for comprehensive identification and evaluation of gas reservoir are established, which are verified by test gas production test results. Thus, the accuracy of gas reservoir identification is improved.
