摘　　要：为了探究含油气盆地斜坡区断裂附近油气分布规律,在输导断裂对沿砂体侧向运移油气作用类型及所需条件研究的基础上,通过确定泥岩盖层垂向封闭区、垂向不封闭区和输导断裂侧向封闭区、侧向不封闭区,叠合各区域以预测输导断裂对沿砂体侧向运移油气作用区。利用此种方法预测渤海湾盆地冀中坳陷霸县凹陷文安斜坡区沙二段输导断裂对沿砂体侧向运移油气作用区,结果表明:文安斜坡区沙二段输导断裂对沿砂体侧向运移油气变径作用区主要分布在其中东部地区,分布面积相对较大;输导断裂对沿砂体侧向运移油气侧接作用区主要分布在其西部中部和南部地区,分布面积较输导断裂对沿砂体侧向运移油气变径作用区要小;输导断裂对沿砂体侧向运移油气阻止作用区仅分布在其西部中部局部地区,分布面积最小。当前沙二段、沙一段、东营组和馆陶组现有油气分布,与沙二段输导断裂对沿砂体侧向运移油气作用区具有一致性,即证明本套预测方法适用于输导断裂对沿砂体侧向运移油气作用区预测。In order to study oil and gas distribution in slope area of oil and gas basin,based on the study of the type and the required condition of the lateral migration of oil and gas along the sandstone about transport transport fault,the vertical closed area of the mudstone caprock,or not closed,and the lateral closed area of the transport transport fault,or not closed.A method for predicting the lateral migration of oil and gas along the sandstone was established and applied to Es 2 in Wen′an slope area,Baxian sag,Jizhong depression of the Bohai Bay Basin.The results showed that the lateral migration reducing function area of oil and gas along the sandstone in Es 2 of Wen′an slope area was mainly distributed in the eastern region,and its large.The lateral migration side joint function area of oil and gas along the sandstone was mainly distributed in the central of the west parts and southern parts,and the distribution area was smaller than the former.And the lateral migration stopping function area of the oil and gas along the sandstone was only distributed in the central part of the west.The distribution area was the smallest.It was found that this method was feasible to predict the lateral migration area of oil and gas along the sandstone,which was consistent with existing oil and gas distribution in Es 2,Es 1,E 3 and N 1g.
