摘要
为解决常规的测井解释方法识别能力较差、区分效果不理想的问题,以永乐油田X区块为研究对象,采用多参数拟合的曲线重构方式,利用曲线重构思想进行测井解释,建立油水识别图版,提高油水识别精度。结果表明,永乐油田葡萄花油层11口井53个试油点中符合点达50个,其中油层23个,油水同层22个,水层8个,符合率达94.3%,符合率较高。该方法可为油水解释图版的建立的提供参考。
This paper aims to solve the problem with conventional logging interpretation methods which have failed to provide a desired distinguishing effect due to their poor recognition ability.The study taking the X block of Yongle oilfield as the research object involves performing well logging interpretation by employing the curve reconstruction method of multi-parameter fitting and the curve reconstruction idea;developing oil-water identification chart and thereby improving the high precision of oil-water identification.The results show that,of the 53oil test points of 11 wells in Putaohua oil layer in Yongle oilfield,there are 50coincident points,including 23oil layers,22oil-water layers,and 8water layers,with a coincidence rate of up to 94.3%,a higher coincidence rate.This method could inform the establishment of oil-water interpretation chart.
