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,取得了明显的地质效果
Conventional logging methods can not effectively reflect the low oil saturation, low resistivity of the reservoir. In this paper, based on the logging response characteristics of low resistivity reservoirs in Chang 6 reservoir of Wuliwan area, combining with the geological and testing data, this paper uses gray comprehensive evaluation method to study and identify such reservoirs with high standardization, automation and speed , And is suitable for non-linear, non-exponential or non-logarithmic distribution, computational workload is small. According to this method, the corresponding processing software has been programmed to deal with some of the well sections that were originally interpreted as a water layer but actually have low resistance to oil and achieved significant geological effects
