| 摘 要： | 在油田前期研究阶段,由于井点资料比较少,往往很难从井点获得河流相储层的小层界面,相变程的大小也无法从统计规律中获得,且由于河道的不断摆动,在曲流河表征过程中主变程方向的设置也是难题。渤海海域Q油田河流相储层受河流不断摆动的影响,纵横向变化快,砂体空间分布状态比较复杂,砂体的表征难度大。为了更加合理的表征Q油田砂体在空间的分布状态,该文提出一种基于井震结合的砂体表征方法,即:通过井震结合划分小层界面,刻画砂体边界,以砂体边界的方向表征主变程方向,在小层框架内,根据沉积规律的指导,结合现代沉积,设置相变程的大小,利用地震属性的约束建立砂体模型。

| Abstract: | Int early stage for studying oilfield, due to few drilling data, it is difficult to obtain sublayer interface of fluvial reservoir in well point, and the size of transformation layer cannot be obtained from the statistical law. Due to the swing of the channels, in the meandering river characterization process, setting main variable range direction is a problem. Fluvial facies reservoir of Q oilfield in Bohai sea is influenced by continuous oscillation of the river. The change in the vertical and horizontal direction is fast, the distribution of sand body is complex, and the characterization of sand body is difficult. In order to characterize the distribution of sand body in Q oilfied in space more reasonably, a sandbody characterization method has been put forward based on the combination of well and earthquake, that is through combination of well and earthquake, seismic interface layers have been divided, and the boundaries of sand bodies have been described. According to the direction of sand bodies boundary, the direction of main variable range has been characterized. In small layer frame, according to the law of deposition, combining with modern transformation process of deposition, by using seismic attribute constraint, sand body model has been set up. |
