摘要
针对在测井资料约束条件下的油藏地质模型精度无法满足进一步提高采收率需要的难题,对利用高分辨率井间地震资料为约束条件的提高油藏地质模型精度的新方法进行了研究。在东营凹陷樊124块利用高分辨率井间地震资料为精细建模约束条件,与其他尺度更广、覆盖空间更大的三维地震资料进行了综合分析,在区块中部发现了一条贯穿整个油藏的近东西向的低序级断层,目的层被分为南北2套油水系统,从而提高了地质模型精度。利用井间地震资料清晰刻画了井间储层的连通及接触关系,从而克服了传统小层对比中难以落实层间连通关系的缺陷,并提出了井间地震资料约束的井间储层连通关系概念模型,为油藏储层的建模提供了新的思路。
In view of the inadequate accuracy of the reservoir geological model constrained by the logging data, the inter-well geophysical data is studied herein to improve the accuracy of the geological model. In the study area of Fan124 block, the geological model constrained by the inter-well geophysical data is combined with the widely covered 2D seismic data for comprehensive analysis, and the low order fault nearly east to west crossing the whole reservoir is located, and the target is divided into 2 oil-water systems with the accuracy enhanced geological model. By means of the inter-well geophysical data, the connection and contact of the reservoir may be described in detail, so as to solve the problem that the connection between layers is hard to be ascertained, and the conception model on connection of inter-well layers constrained by the inter-well geophysical data is proposed herein for the new idea on the model construction of reservoir.
