Evaluation And Application Of Logging Technological Series In The Castern Sulige Gasfield

Response to the complex characteristics of low porosity and low permeability,heterogeneous, non-linear distribution and logging in the Sulige eastern gas field tight gasreservoirs, carry out the routine use of the area more than10kinds of logging methods foroptimization and evaluation studies. For statistical comparison of the abnormal difference inthe size of argillaceous rocks and dense dry layer of well logs and application area46wellsmore than500different types of tight gas reservoirs, respectively, evaluation divided intodifferent series, better poor logging methods and techniques. Lithologic series illustrates thespontaneous potential, natural gamma ray spectrometry logging for natural gamma ray loggingfor better caliper logging and photoelectric absorption cross section index logging center. Theporosity Series to the density, acoustic logging, neutron porosity logging is poor. Series ofresistivity of high-resolution array induction logging, high-resolution array laterolog better,and bilateral to the logging center. Through the depth of diagenetic reservoir facies andpetrophysical facies classification of logging interpretation methods applied research,evaluation criteria of the different categories of gas-bearing tight gas reservoirs, and old wellspotential layer review Potential to determine the different types of new gas-bearing bits,effectively clarify the series of well logging technology in tight gas reservoir evaluation of therole and practical effect to enhance the tight gas reservoirs logging qualitative identificationand quantitative evaluation of capacity for tight gas reservoirs selected logging methods andtechniques, developed to increase measured the new method of implementation of the project,provide a reliable basis for economic and practical logging series and gas fields to increasereserves and production.
