摘要
对煤层气井注入/压降测试分析的理论、方法及应用进行研究。将试井理论应用于实际中,得到了白芨沟煤层气藏的渗透率、储层压力、表皮系数、煤层闭合压力等储层参数,综合已经取得的地质资料对这些参数结果进行分析判断,表明该结果基本符合实际情况。后期的煤层气生产井设计、井网规划采用了这些数据,提高了生产井的产量,取得了很好的经济效益。
Theory,method and application of injection/down pressure testing analysis for CBM is studied and some of formation parameters of permeability,reservoir pressure,skin factor and closure pressure have been gained.For analyzing these comprehensively obtained geologic data,it is judged that these values are corresponds to actual situation basically and these data are used for later period of production well's design and plan of well net which increases productivity and income and gains a good economical effect.
