延川南煤层气临界解吸压力误差分析

摘要

Based on the data from CBM parameter well in Yanchuan south block, the authors of the paper studied carefully all the steps in computation of the figures of the critical desorption pressure obtained from ex- periments and the influencing factors. Based on the known data, the authors analyzed the major influencing factors, such as reservoir pressure, measured gas contents, measured gas content saturation degree, etc. They summarized the rules of regional errors, which are of significance in guiding site production.%本论文以延川南区块部分煤层气参数井数据为基础,从实际问题出发,仔细分析临界解吸压力实验值计算过程中的各个步骤和影响因素,根据已知数据,对主要影响因素如储层压力、实测含气量、实测含气量饱和度等进行分析,总结了该区域的误差规律,对现场生产有一定的指导意义。
