摘　　要：A油田主力油藏Q由多期三角洲沉积体、重力流沉积体交互叠置而成,储层内部结构复杂。同时,储层平均厚度小于8m,地球物理识别难度大。针对这些情况,通过开展地震波形指示反演研究,提高储层预测分辨率及准确度,解决识别难度大的问题;通过开展储层构型研究,刻画出各期砂体空间结构特征,解决储层结构复杂的问题。最终,进行井网优化调整,改善开发效果。本次研究为后续其他类似油田提供借鉴。The major reservoir Q of A oilfield is composed of several delta deposits and gravity current deposits which interactive overlay together. The average thickness of Q reservoir thin than 8 meters which is a challenge when realizing by Seismic data. Because of this,the author using the SMI technology to improve the reservoir prediction resolution and accuracy rate;applying reservoir configuration technology to describing these sands spatial structure character which solve the internal complex problem. Finally,optimize the well pattern. These research can be used in similar oilfields.
