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 ;说明该方法可行
Aiming at the difference of neutron gamma logging curve units measured in different wells of the same well at different time intervals, a normalized method of neutron gamma logging curve is proposed. When there is aquifer, the scale of mudstone and aquifer should be prioritized Method to realize the standardization of well logging curve. The parameters of gas layer identification and the degree of gas utilization are established. A method of qualitatively identifying the gas layer and judging the utilization degree of the gas layer is proposed. By using this method, more than 10 wells in the northern part of Xinglongtai of Liaohe Oilfield Compared with the test results, the coincidence rate is high; this method is feasible
