摘要
为研究气体动力煤储层改造的效果,利用结果检验阶段的压力恢复观测数据,运用气藏工程分析理论与方法,对煤储层的渗透率、表皮系数、有效井半径、井筒储集系数等影响煤层气井生产性能的参数进行计算,通过分析这些参数在改造过程中的动态变化,探讨每一循环气体动力改造煤储层的效果,为优化调整作业参数和作业方案提供依据,指导气体动力改造作业达到最佳效果。
To study gas-kinetic coal reservoir reformation effect, through pressure buildup observation data from result checking stage,using gas reservoir engineering analytic theory and methodology, carried out computation of parameters impacting CBM well productivity such as coal reservoir permeability, skin factor, effective well radius and well-bore accumulation coefficient etc. Through analysis of dynamic variation of the parameters during reformation process, discussed effect of each cycle gas-kinetic coal reservoir reformation,thus provided basis for operation parameter and scheme optimization and adjustment to guide gas-kinetic reformation get best effect.
