摘要
针对同一口井不同时期测量的中子伽马测井曲线刻度单位的不同 ,提出了中子伽马重复测井曲线的标准化方法 ;在有水层存在时 ,应该优先采用泥岩和水层的刻度方法来实现测井曲线的标准化 ;构建了气层识别参数和气层动用程度指示参数 ,提出了定性识别气层和判断气层动用程度的方法 ;采用该方法对辽河油田兴隆台北部 10余口井进行处理 ,与试气结果对比 ,符合率较高 ;
In the paper two methods are proposed to normalize NGR (Neutron Gamma Ray) logs since NGR logs measured at different periods in one hole are often recorded with different units. Testing over ten wells proves that two methods are applicable. When there is water\|bearing in a well, the method calibrated in shales and water\|bearing zones is used first. Gas bearing zones can be determined qualitatively by gas identification parameters. Dynamic production in gas zones can be reflected by indication parameters of dynamic production of gas. The proposed methods proved to be applicable in north area of Xinglongtai, Liaohe Oil Field through comparing interpretation results with gas\|testing results.
