【摘要】 磨盘场潜伏构造位于大池干井构造带中段,主体构造东南侧断下盘的一个次一级的潜伏圈闭构造。该气藏于1990年投入试生产,1997年完成开发方案,方案中遗留了一些问题,2003年开展气藏生产影响因素及调整措施研究,在研究过程中发现,该气藏存在两个压力系统,且根据2002年地震测线解释及动态表现,表明池37井区落在⑨号断层的下盘,但边界不明,含气范围不能确定。文章利用动态分析方法,结合地质构造研究成果,证实了该气藏存在两个含气区块的推论,并最终确定了池37井区的构造形态和含气面积。根据气藏气井动态表现特征,结合有限的地质资料反向思维,推导出储层构造形态和含气面积,是本次研究工作中动、静结合的特点。更多还原

【Abstract】 Mopanchang buried structure lies in the meddle section of Dachiganjing structural belt, and is a sub-level buried trap structure in the down-throw block of the southeast side fault of the major structure. The gas reservoir was put into production in 1990. The development program was completed in 1997. Some problems are remained in the program. The study on the effect factors and adjust measures of the gas reservoir production is conducted in 2003. During the study, it is found there are two pressure systems in the gas reservoir. According to the seismic interpretation in 2002 and the performance behavior, it is indicated well Chi 37 producing tract falls on the down throw block of No. 9 fault, but its boundaries are not clear and its gas-bearing range can’t be determined. With performance analysis method, integrating the geological structure, it is demonstrated there are two gas-bearing blocks in the gas reservoir. Finally, the structural shape and the gas-bearing area of well Chi 37 producing tract are determined. According to the performance behavior of gas wells, integrating the limited geological data, with reversed thinking, the structural shape and the gas-bearing area of the reservoir are derived, which is the feature of the study to combine the dynamic and static status.更多还原
