摘要

基于对泥岩和储集层异常压力的研究,分析了渤海湾盆地辽中南洼古近系超压封存箱结构及其对油气运移的影响。研究区压力封存箱呈“三明治”结构,古近系东营组超压泥岩为压力封存箱的盖层顶板;古近系沙河街组上部储集层/输导层为压力封存箱内的“夹心层”;沙河街组下部泥岩为压力封存箱的烃源灶。基于储集层超压形成机制研究和盆地模拟方法,恢复了“夹心层”在新构造运动前后的压力分布,对新构造运动中郯庐断裂带活动导致的压力封存箱破裂和压力分异进行了研究,对新构造运动前后不同压力环境下的油气运移进行模拟,由此把郯庐断裂带新构造运动、异常压力和油气运移关联起来。模拟结果表明:新构造运动中,由于郯庐断裂差异活动,“夹心层”产生压力分异,流体势梯度大幅增加;走滑拉分区发生泵吸作用,形成低势区,是油气运移的主要方向。综合辽中南洼晚期成藏特征,研究认为:静态上,存在压力封存箱箱内成藏体系和箱外常压成藏体系。动态上,箱内“夹心层”的油气聚集为箱外油气成藏的“中转站”,决定了油气的平面分布。图13参50

Abstract

Based on the study of the abnormal pressure of mudstone and reservoirs of south Liaozhong sag, Bohai Bay Basin, the structure of the abnormal pressure compartment in the Paleogene of south Liaozhong sag and its impact on oil and gas migration have been analyzed. The pressure compartment in the study area has a “sandwich structure”, with the mudstone of Paleogene Dongying Formation as cap rock, the reservoirs of the upper Shahejie Formation of the Paleogene as the transport interlayers, and the mudstone from the lower Shahejie Formation as the hydrocarbon source rock. Based on overpressure formation mechanism and basin-modeling, the pre-neotectonic movement pressure of the transport interlayers was reconstructed, then the rupture of the pressure compartment and pressure differentiation caused by Tanlu fault zone during the neo-tectonic movement were investigated. The hydrocarbon migration was simulated under different pressure conditions before and after the neo-tectonic movement, to find out the relationship between the neo-tectonic movement of Tanlu fault, abnormal pressure and oil and gas migration. The simulation results show that the differential activity within Tanlu fault zone caused the differentiation of pressure and increase of fluid potential gradient; and the strike-slip pull-apart area with low potential caused by pump-sucking effect became the main direction of hydrocarbon migration in Tanlu fault zone. The comprehensive research of the late-stage hydrocarbon accumulation shows that, there are inner and outer compartment hydrocarbon accumulation systems in the south Liaodong sag, and the transport interlayer in the inner compartment is the “hydrocarbon transfer station” of the shallow outer compartment, and determines the hydrocarbon plane distribution.
