摘要
常规的测井方法不能有效地反映低含油饱和度、低电阻率的油气层.本文根据五里湾地区长6油层组出现的低阻油层的测井响应特征,结合地质和测试资料,采用灰色综合评判方法来研究和识别此类油气层,具有较高的标准化、自动化和速度,且适用于非线性、非指数或非对数分布,计算工作量小.依此方法编制了相应的处理软件,处理了一些原来被解释为水层而实际上是低阻含油的井段。
おonventional well logging methods can't detect low-oil saturation,low-resistivity oil-gas zones effectively. Based on the response features of logs to low-resistivity oil-gas zones in Wuliwan. Combining geological and testing information,we propose to use grey comprehensive evaluation in our intestigation and identifing this kind of oil-gas zones. And the software is devolpped according to the method.It has been used in the processing of some low-resistivity、oil-gas bearing intervals being thought water bearing in Waliwan and the obvious results are achieved.
