浅谈鸭儿峡油田第三系M、K层开发潜力

鸭儿峡油田M层在20世纪50年代有10口井试油,从试油井情况分析,当时的试油主要以提捞为主,没有进行措施改造,而且油井产出的水含盐很低,基本为井筒水,并不能落实地层含水情况。鸭儿峡油田K层曾经有4口井试油,试采效果不好,均为水。从已试油井SP曲线看,储层是存在的,但电性特征表现为水层,没有找到油层电性特征,是试油失败的主要原因。本文通过对比和分析M、K层试油井电性特征与试油结果的相关性,找出含油性和电性的对应关系,分析和评价M、K层的潜力。

On the Tertiary System M, K Layer Development Potential of Yaerxia Oilfield

There are 10 wells at tertiary system M layer of Yaerxia Oilfield in the 1950s.The formation test is mainly bailing,they are not reformed,salt content in water from oil well and most of them are shaft water,and the layer water bearing is unknown.There are 4 wells at tertiary system K layer of Yaerxia Oilfield.Their production test results are not satisfactory,all of them are water.From the SP curve,reservoir exists,but the electrical characteristics shows that it is the water layer,without the electrical properties of oil formation,which is the main cause of formation testing.Comparing and analyzing the relativity of the electrical properties and formation testing result of M,k layer oil wells,the article found out the correspondence of oiliness and electrical property,and the potential of M,K layers.
