大牛地气田D区块山1段三维地震储层预测
|
摘要
大牛地气田D区块山1段储层为煤系储层,煤层产生的强反射掩盖了储层的反射特征。通过地震反射特征和钻井统计分析,认为:煤系储层与煤层的发育在空间上存在一定的互补关系,并且山1段储层发育时地震剖面表现为波形加宽或同轴相增多。以此为基础,通过预测煤层寻找有利储层靶区,再利用针对性的地震储层预测方法技术定性定量地预测山1段储层展布和储层的含气性。预测出3个山1段有利储层分布带,综合储层预测成果与钻井符合率达90%以上。
Reservoir of the Segment 1 of Shanxi Member(S1)in block D,Daniudi gas field is a coal measures reservoir.The strong reflections from coal mask the reflections of reservoir.From the study of seismic reflection characteristics and well log statistics,it is concluded that coal and reservoir are spatially complementary,and wiggles widen or number of events increases on seismic sections when reservoirs of S1 are developed.Thus a method that predicting reservoirs by predicting coal is proposed,that is,firstly predicts the distribution of coal to indirectly predict the distribution of reservoir,and then further delineate the reservoir of S1 and determine its gas-bearing potentials.Four reservoir zones have been predicted.The coincidence rate with wells exceeds 90%.
