摘要
提出了应用曲率预测裂缝性油气藏的裂缝发育程度及分布状况的方法,阐述了曲率法的原理及确定曲率的方法,应用该方法恢复了松辽盆地徐家围子断陷深部的营城组地层的发育史,计算了该地层在登娄库组、泉头组、嫩江组及现今各时期的曲率值,根据曲率法原理预测了该区的裂缝发育状况及油气的分布。预测结果与实际钻探、观察结果吻合较好,表明结合地层发育史用曲率计算法预测裂缝发育带是可行的。
This paper mainly focuses on the research of how to forecast the fissure development degree of the crack in oil reservoirs and their distributing patterns. Firstly we expounded the principle and the method of curvature method, and then we restored the development history of the Yingcheng Formation stratum of Xujiaweizi fault depression of Songliao Basin based on this method. After we computed the curvature values of this stratum in Denglouku Formation, Quantou Formation, and Ninjiang Formation in various periods, we forecast the fissure distributing patterns based on these values. The result inosculates well with the real result from drilling and observation, which indicates that this method is feasible to forecast the fissure patterns combined with the development history of the stratum.
