摘要
以潘庄煤层气井为例,根据煤层气井的开发特征,制订了“522”排采制度优化思路;利用分类和大数据统计的方法,从检泵周期和产气量两个维度对不同井型不同煤层的煤层气井进行了排采制度优化,得到煤层气井不同排采阶段排采工作制度定量优化的一种方法。这为煤层气井排采制度的定量优化提供了思路和借鉴,尤其对目前排采经验相对较少的深部煤层气的开采有着很重要的参考价值。
Taking the coalbed methane wells in Panzhuang as an example, and based on the development characteristics of coalbed methane wells, a “522” optimization strategy for the drainage system is proposed. By using classification and big data statistics methods, the drainage system of coalbed methane wells in different types and coal seams is optimized from two dimensions: pump inspection cycle and gas production rate. This study presents a quantitative optimization method for the drainage system of coalbed methane wells at different drainage stages. The findings provide valuable insights and references for the quantitative optimization of coalbed methane drainage system, especially for the extraction of deep coalbed methane with relatively limited extraction experience.
