【摘要】：济阳坳陷义和庄地区潜山内幕构造演化复杂、控藏作用不明,制约着该区潜山内幕油气勘探。综合地震、测井、岩性及分析化验等资料开展了义和庄地区潜山内幕构造演化特征分析,并据此评价了构造演化对油气成藏的控制作用。结果表明,研究区潜山经历了印支运动挤压抬升、燕山运动Ⅰ幕挤压、燕山运动Ⅱ幕拉张沉降、燕山运动Ⅲ幕挤压抬升以及喜马拉雅运动拉张沉降这一演化过程;义古991断层为潜山内幕典型同沉积断层,其断层活动速率验证了潜山的构造演化过程;多期次不同应力性质的构造演化使潜山内幕断层经历了多个逆冲、负反转阶段;潜山内幕的多期构造演化过程有利于优质储层和高效输导体系的形成,同时多期构造演化过程与内幕隔层相匹配有利于形成良好的储盖组合与多种圈闭类型。在构造演化分析、有利输导体系预测与有利圈闭描述的勘探思路指导下,成功发现了义古72和义古65块等潜山内幕油藏。
[Abstract]:The tectonic evolution of Qianshan inner curtain in Yi and Zhuang area of Jiyang depression is complicated and the function of reservoir control is unknown, which restricts the exploration of Qianshan interior oil and gas in this area. Comprehensive seismic, logging, lithology and analysis and testing data have been carried out to analyze the structural evolution characteristics of Qianshan curtain in the Yi and Zhuang area, and the control effect of tectonic evolution on oil and gas accumulation is evaluated. In the study area, Qianshan has experienced the evolution process of the compression and uplift of the Indo Chinese movement, the extrusion of the Yanshan movement I act I, the tension and subsidence of the Yanshan Movement II act, the extrusion and uplift of the Yanshan Movement III act and the subsidence of the Himalaya movement, and the typical synsedimentary fault of the Qianshan inside the Yi Gu 991 fault, and its fault activity rate verifies the tectonic evolution of Qianshan. The process of the tectonic evolution of multiple periods of different stress properties made the Qianshan internal fault experienced several thrusts and negative reversals, and the multi-stage tectonic evolution process in Qianshan was beneficial to the formation of high quality reservoirs and high efficient transport systems. Under the guidance of structural evolution analysis, favorable transport system prediction and favorable trap description, Qianshan internal oil reservoir, such as Yi Gu 72 and Yi Gu 65, have been successfully found.
