断块油藏开发后期精细构造研究
|
摘要
针对濮城油田沙二上段Ⅰ砂岩组油藏构造复杂、断块破碎和特高含水开发后期的地质特点,运用构造整体解释与精细研究相结合,利用地震层位精细标定、地层精细对比、三维地震人机联作精细构造解释、开发井间精细油层分析等技术,对各开发层位微构造进行了研究,落实了油藏整体构造格局及断层在空间上的展布状况,进一步修正内部小断层的产状及相互切割关系,搞清了构造特征对油气分布的控制作用。对进一步挖潜剩余油,提高油藏开发水平具有重要的地质意义。
Sand Unit I of upper Es2 in Pucheng Oilfield has characteristics of structure complexity,fault block breakability,and features of production tail with extra high water cut.This paper studies the microstructure of each pay zone,confirms overall reservoir structure and spatial distribution of faults,further revises the occurrence and in-ter-cutting relationship among interior minor faults,and understands the controlling effect of structure on hydro-carbondistribution by combining overall structure interpretation with fine structure study and using techniques of seismic horizon identification,strata correlation,3D seismic IDIMS fine structural interpretation,and interwell reservoir analysis.This study is of geological significance to producing remaining oil and improving reservoir development.
