束鹿凹陷西斜坡中部成藏因素分析
|
摘要
束鹿凹陷存在多种圈闭类型的油藏,由于岩性复杂、断层发育等因素,导致凹陷内油气成藏规律性差异很大,需要进一步认识成藏主控条件。综合利用地震、钻井、测井、地质及地球化学等资料,研究区内烃源岩分布规律和断层系统的发育特征,进一步总结了断层与烃源岩的空间配置关系对区内油气成藏的控制作用。其中,晋105、晋95、晋93以及晋94断块油气成藏均受控于断层与烃源岩的空间配置关系。研究断层与烃源岩的空间配置关系,对区内可能发育的有利油气区带进行预测,为研究区勘探开发提供了有利的方向。
Reservoirs with different kinds of traps exist in Shulu depression and the hydrocarbon accumulation patterns differ greatly within the depression due to complicated lithology and well-developed faults,so the major control conditions of the accumulations need further understanding.This paper comprehensively used the seismic,drilling,logging,geologic and geochemical data,investigated the distribution patterns of the source rocks and the development features of fault systems in the study area,and summarized the control function of the spatial configuration between faults and source rocks on the hydrocarbon accumulations in the area.The hydrocarbon accumulations in fault block Jin105,Jin95,Jin93 and Jin94 are all controlled by the spatial configuration between faults and source rocks.The investigation of the spatial configuration between faults and source rocks could predict the potential favorable oil and gas zones and provide guidance for the exploration and development of the study area.
