| 摘 要： | 准确识别致密砂岩含气层一直是测井解释工作所面临的一个难题，为准确识别致密砂岩含气储层，根据各种测井的响应特征，运用计算机模式识别技术进行气层综合识别。通过对实际资料处理与气层测试对比，气层识别的准确率可达到91％，储层划分的纵向误差均〈0．450m。

| Abstract: | It is a difficult to solve the problem in log data interpretation to distinguish accurately gasbearing formation. Based on the character of log data response, the authors used the computer pattern recognition technique to identify it synthetically. By comparison with processing of actual data and the gas-bearing test, it can approach to 91% in accuracy rate for distinguishing gas-bearing formation, with the lengthwise error of reservoir zonation less than 0.450 m. |
