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。
Aiming at the geological characteristics of the complex sandstone reservoir in the upper section of Sha2 in Pucheng oilfield, which is characterized by complex structure, broken block and late stage of ultra-high water cut, this paper uses the tectonic interpretation and meticulous study. Seismic interpretation of fine structure of human-machine interaction, the development of cross-well analysis of fine reservoirs and other technologies to study the micro-structure of the development of strata, the implementation of the reservoir structure and the distribution of the overall fault in space to further amend the internal small Fault occurrence and mutual cutting relations, to clarify the tectonic features on the control of oil and gas distribution. It has important geological meaning to further tap the residual oil and improve the level of reservoir development.
