沾化凹陷垦西油田南部馆陶组岩性油藏勘探取得进展,已有多口井见到油气显示,但是本区河道砂体横向变化快,砂体描述方法单一。本次在精细构造解释的基础上,用层序约束地震复合属性的方法,多种方法综合描述,明确各期次河道的切割关系及相互间的连通性,通过微构造与砂体匹配,将垦西油田南部馆上段河道砂体分类,使得井位部署方案更加优化,新部署井位均见油气,应用效果显著。
Progress has been made in the exploration of lithologic reservoirs in the Taohe Formation of the southern part of Kenxi Oilfield in Zhanhua Depression. Many wells have seen oil and gas exploration, but the lateral variation of channel sand bodies in this area is rapid with a single sand body description method. Based on the explanation of the fine structure, this paper uses the method of sequence attributes to constrain seismic attributes and comprehensively describes the cutting relations and inter-connectivity of various channels. Through the matching of microstructures and sand bodies, The classification of sand bodies in the upper section of southern section of Kenxi Oilfield makes the well site deployment plan more optimized. Oil and gas are all found in newly deployed wells, and the application effect is remarkable.
