尚店油田目前已处于高含水开发阶段,产量递减快,剩余油分布零散。为提高油田采收率,减缓产量递减,需要研究剩余油分布规律,挖潜剩余油。在充分利用地震、测井、钻井资料的基础上,对该油田精细油藏描述,建立可靠的地质模型,运用油藏工程理论对其开发现状进行分析和评价。围绕剩余油,开展剩余油研究技术、小层剩余油分布、层内剩余油分布等三个方面的研究工作。
Shangdian Oilfield is currently in the stage of high water cut development, with decreasing output and remaining oil scattered. In order to increase oil recovery and slow down production decline, it is necessary to study the distribution of remaining oil and tap the residual oil. On the basis of making full use of seismic data, logging data and drilling data, this paper describes the fine reservoirs in the oilfield, establishes a reliable geological model, and analyzes and evaluates the current status of its development by using reservoir engineering theory. Surrounding the remaining oil, the research work on the remaining oil research techniques, the distribution of remaining oil in small layers and the distribution of residual oil in the layers are carried out.
