摘要
低阻油藏作为一类非常规储层,受多种因素控制。而低阻是由沉积、成岩作用、储层高束缚水饱和度等所致;此外还有构造、流体性质及泥浆滤液侵入等外因的综合影响。不同地区的低阻油层成因机制不同,其特征表现也不尽相同。重新对低阻油藏的认识,特别在油藏后期开发方面,如:油层的查层补孔,滚动扩边等方面很有用处。本文主要阐述了靖安油田大路沟一区低阻油藏成因和油水层识别方法。
As a kind of non-conventional reservoir,Low resistance reservoir is controlled by many kinds of factor.But the low resistance is caused by deposition,digenesis,height irreducible water saturation and so on,in addition,the external factor,such as geological structure,properties of fluid and the intrusion mud filtrate also affect the low resistance.The low resistance reservoir in the different area has different genetic mechanism and features.Rerecognizeing the low resistance reservoir has the vital significance regarding the oil deposit later period development.This thesis explained the cause of the the low resistance reservoir and the recognition methods of oil-water layer to Jing-an oil field da lu gou No.1area.
