本文以河68断块为例,通过采用三维地震资料目标处理技术,为识别低级序断层提供了可靠的基础资料;利用多井精细对比技术,确定了低级序断层断点;应用全三维解释技术,识别和组合了低级序断层;运用多尺度边缘检测技术,确定了低级序断层的空间组合及走向;最后综合动态分析技术,进一步验证了低级序断层的合理性,从而实现了河68断块低级序断层的精确描述,并指导了剩余油分布研究。该研究成果应用于河68断块沙二段细分层系井网调整中,取得了较好的开发效果,注采对应率及水驱控制程度大幅提高,采收率提高了1 0.5个百分点。
In this paper, the fault block of river block 68 is taken as an example. By using the 3D seismic data target processing technology, it provides reliable basic data for identifying low-grade faults. Using the multi-well fine contrast technique, the low-order fault breakpoints are determined. , Identifying and combining low-level sequence faults; using multi-scale edge detection technology to determine the spatial combination and trend of low-level sequence faults; finally, the dynamic comprehensive analysis technology further verifies the rationality of low-level sequence faults, Accurate description of low-level faults and guide the study of remaining oil distribution. The results of this study are applied to well pattern adjustment of the fine-graded strata in the second member of the Shahejie Formation of the river block 68 and achieved good development results. The correspondence rate of injection and production and the degree of waterflood control were greatly enhanced, and the recovery rate increased by 1 0.5 percentage points .
