摘　　要：汪家屯气田在“八五”期间曾是大庆油田外围发现的最大气田 ,但随着对气田初步开发方案、开发地震等工作的实施 ,经过对气田进行的精细地质描述、动态分析、小断块数值模拟等综合研究 ,发现气田是由多因素控制的低渗透复合型气藏群组成的 ,原在探明初期应用容积法计算的储量误差较大 ,使得气田储量减少幅度达6 0 %。文章论述了汪家屯气田地质精细研究成果 ,通过动态分析与数值模拟 ,分析研究了气田的开发特点及增产界限 ,为今后评价和开发这类气田提供了借鉴经验。Wangjiatun gas field was the largest gas field, which found during 'the Eighth 5-year's plan' in the skirt of Daqing oil field. As the initial scheme of the gas field development arid the development seismic jobs, etc. were conducted, with the integrated study of the fine geologic description, producing performance analysis, and numeral simulation for small faulted blocks, etc., it is found the gas field consists of a complex group of low permeable gas reservoirs controlled by many factors. The reserves calculated with volumetric method in initial producing stage have big error. The reserves proved now are only 40% of the original calculated reserves. The article introduces the results of the fine geologic survey for Wangjiatun gas field. With producing performance analysis and numeral simulation, the production characteristics and productivity limit of the gas field are analyzed. The article provides the reference for evaluation and development of the similar gas fields in future.
