T1区块做为FX油田主产区块,其扶余油层为主力油层,主要为三角洲前缘的分流河道砂体,存在横向变化快,平面不稳定的特征,为外扩钻井、新井区动用带来较大风险,为提高储层认识程度,加强河道砂体预测,陆续开展了以井-震结合为主的储层预测研究,通过不同地震属性的分析、砂体预测方法的研究,总结了一套对T1区块扶余油层有效的砂体预测方法,并进行了预测精度分析和应用,取得了较好的效果。
T1 block is the main production block of FX oilfield. The Fuyu oil layer is the main oil layer and is mainly distributary channel sand body in the delta front with the characteristics of rapid horizontal variation and plane instability. In order to increase reservoir awareness and strengthen the prediction of channel sand bodies, reservoir prediction studies based on well-seismic combination have been carried out one after another. Based on the analysis of different seismic attributes and the study of sand body prediction methods, A set of effective sandbody prediction methods for the Fuyu oil layer in Block T1 are presented, and the prediction accuracy analysis and application are also made. The good results are obtained.
