摘要
以沁水煤层气田开发实践为基础,建立煤层气压裂直井理想产量模型和全生命周期产量预测模型,通过Eclipse软件数值模拟分析煤层气井压降模型,结合实际生产规律统计,分析不同开发地质条件煤层气井全生命周期内产量与生产时间的关系,确定稳产气量、递减率及各阶段资源采出程度等气田开发关键指标。
Based on the CBM development in Qinsh and the life cycle of production increasing trend for a ui Basin, models of theoretical production potential CBM vertical well are developed, and coal reservoir pressure transmission model is studied using Eclipse software. Combining with production statistical regu- larity and models analysis, the life cycle of gas production with different reservoir condition are studied. Key indices, such as stable output, decline rate, recovery percent at different stage of development are determined.
