摘要
Y128井区是特低渗透气藏,地质情况复杂。为了解储层类型、边界情况,针对Y128井区实际情况,根据渗流力学基本原理,应用Saphir4.12试井解释软件,对Y128井区75口气井进行压力恢复试井解释。结果表明,Y128井区气藏模型主要有均质型、无限传导型、有限传导型、径向复合型四种,气井裂缝流十分短暂,外围储层物性变差,储层非均质性严重。
Y128 well area is the super low permeability gas reservoir,whose geological condition is complex.To understand the reservoir type,boundary condition,and the actual situation for the Y128 Well,according to the basic principles of fluid mechanics,build up pressure well testing interpretation have been done in 75 gas wells at Y128 Well area by applying Saphir4.12 well test interpretation software.The results show that gas reservoir models at Y128 well area are mainly four types of homogenous,infinite conduction,finite conductivity type and radial composite,crack flow of gas well is very short,the external reservoir properties are becoming bad and reservoir heterogeneity is serious.
