摘要
基于沁水盆地柿庄南区块3#煤层储量丰度、临储比及渗透率参数分布,统计上述参数影响范围内有效井(工程质量好,生产时间超过1 a)的平均产气量,采用灰色关联度分析方法,确定主地质参数评价值函数及权重系数,建立产能预测公式。借助Petrel软件,建立离散化的产能预测属性模型,得到平均产能预测图。根据煤层气开发平均产能类型划分标准,划定煤层气开发类型。此研究可为后期生产提供开发依据,指导柿庄南区块下一步方案部署。
Based on the 3#coal reserve abundance,critical desorption,reservoir pressure and permeability distribution maps of southern Shizhuang block in Qinshui basin,the average gas production rate of effective wells,located in the search radius of the above parameters with good construction quality and long production time more than a year was obtained. The analyzing method of grey relativity was used fordetermining the main geological parameter evaluation function and weight coefficient.And then production forecasting formula was established. Applying Petrel software, discrete production forecasting model was established and average production forecasting map was drawed. According to the classification standard of well productivity, different CBM development areas were divided.This study can be used to forecast the productivity of southern Shizhuang block and guide the CBM well drilling.
