济阳坳陷桩海地区古潜山油藏控制规律及有利区预测
|
摘要
为研究济阳坳陷桩海地区的古潜山油藏控制规律,通过大量二维地震剖面解释,绘制了研究区中、古生界沉积残留厚度图,编制了基底构造纲要与油藏分布图。研究表明,12条大断裂控制了本区大地构造格局,并控制了中、古生界的沉积残留厚度,古生界残留厚度为0～2 200 m,中生界残留厚度为0～3 900 m。桩海地区有效烃源岩主要为沙河街组和馆陶组,储层为寒武—奥陶系地层,沙河街组泥岩为良好盖层,断裂和不整合面作为运移通道。根据12条断裂所分割的区域,将研究区划分为8个区块,并对其作了成藏预测。
In order to study the controlling rule of buried hill reservoir in Zhuanghai Region,Jiyang Depression,we draw the chart of relict sediment thickness and the map of basal structure and reservoir distribution in Mesozoic and Paleozoic in the area on the basis of the interpretation of 2D seismic profile.Study results show that twelve faults control the tectonic frame of the region and control the relict sediment thickness in Mesozoic and Paleozoic.The relict thicknesses are separately 0-2,200 m in Paleozoic and 0-3,900 m in Mesozoic.The effective hydrocarbon source rocks are mainly Shahejie Formation and Guantao Formation in Zhuanghai Region.The reservoir rocks are Cambrian-Ordovician strata.The mudstones of Shahejie Formation are favourable cap rock.Fault and unconformity surface are the migration pathway of hydrocarbon.According to the partition by 12 faults,the region is divided into eight blocks and the prediction of hydrocarbon accumulation is conducted in the region.
