摘要(Abstract)：

汪家屯气田扶、杨油层气藏在开发过程中出现储量动用程度低、气井稳产期短、产量递减快、开发动态与地质认识不符等问题。为了重新认识气藏、增加气藏动用储量、提高采收率,在地层对比、三维地震构造解释及储层预测等地质研究基础上,进行了气井动态特征分析、气井产能评价、单井井控动态储量计算、井间连通关系等研究;评价了气藏井网适应性,明确了气藏剩余潜力分布及大小;编制了气藏开发调整方案,并采用数值模拟方法进行井距论证和开发指标预测。
The following problems are met during the development process of Fuyang oil reservoirs in Wangjiatun Gasfield:the low produced recovery of the reserves,short period of the stable production,rapid decline of the production and disaccordance between the reservoir performances and geological understandings.In order to renew the knowledge of the gas reservoirs,increase the developed reserves and enhance the recovery,the following studies are conducted on the bases of the geological researches including the stratigraphic correlation,3D seismic structural interpretation,reservoir prediction and so forth;analysis of the dynamic characteristics and productivity evaluation for the gas wells,calculation of the performance reserves controlled by the individual well,interwell connectivity and so on;the compatibility of the well patterns is evaluated and then the distribution and size of the remained gas reserves are made clear;compiling the development adjustment programs of the gas reservoirs and moreover adopting numerical simulation method to discuss and demonstrate the well spacing and finally predict the development indexes.
