摘要

探讨了密井网条件下曲流河点坝体内部侧积体描述技术。在大庆油田精细地质研究成果基础上,研究了储层内部的非均质性,以层次分析法、结构要素分析法等为指导,提出了侧积体结构要素表征的概念、描述方法、曲流河点坝体井间隔夹层预测方法。所提出的方法为精细解剖曲流河沉积砂体、挖掘厚油层层内剩余油潜力提供了手段。研究成果在大庆油田南一区甲块水平井轨迹设计中得到了具体应用,并见到了实效。

Abstract

The description technology of inner lateral accretion within point bar of meandering river under the condition of infill drilling well pattern is introduced. On the basis of fine geologic research conducted in Daqing Oilfield, the reservoir heterogeneity is studied. Based on the analysis of formation sequence and structure elements, the concepts in terms of lateral accretion structure characteristics, as well as description method and prediction method for the interlayer located in point bar of meandering river are proposed. These methods provide effective way for the fine study on sedimentary sand body of meandering river and the further development of remaining oil within thick reservoir. The study results were applied to the locus design of horizontal well in Daqing Oilfield, and good result has been achieved.
