摘要
卫星油田PⅠ层组为该油田的主力油层组,层组内单砂层厚度较薄、空间连续性差。将PⅠ层组纵向上划分为上、中、下3个组合单元,利用地震波形能够给以较好的反映。测井曲线具备好的沉积微相识别能力,将每个单元里存在河道或河坝砂体定义为砂体发育,不存在的定义为互层发育,考察卫星油田三维地震工区近100口井资料识别的沉积微相与地震波形的对应关系,建立8种地震波砂体反射模式,依据模式可有效推测出卫星油田PⅠ层组勘探空白区的砂体发育状况,为该油田部署有利井位提供技术支撑。
Bed set P I is the main reservoir group in the Weixing Oilfield, characterized by thin thickness of single sand layer and poor spatial continuity. Bed set P I can be divided into 3 composite units, which can be well reflected by the seismic wave shape. Well logs have perfect identification capacity for sedimentary micro-facies. The unit with channel or river dam sand body is defined as sand body development, and that without channel or river dam sand body is assigned to interbed development. The authors investigated the corre- sponding relationship between sedimentary micro-facies identified by well log data of 100 wells in 3D survey of the Weixing Oilfield and the seismic wave shape and, on such a basis, established 8 types of sand body reflection mode of seismic wave. According to the mode, sand body development can be derived for the exploration blank area of Bed set P I of the Weixing Olilfield. The results provide techno- logical support for the deployment of favorable well locations.
