| 摘 要： | 煤层气的产出机理决定了煤层气井必须进行排水降压,才能达到产气的目的。文章分析了当前我国煤层气井排采的主要方法及其适应性,指出合理的排采制度和精细的排采控制是保证煤层气井排采成功的关键排因素。认为非连续性排采、排采强度过大及井底流压降低过快是影响我国煤层气井产量的主要工程因素。

| Abstract: | Drainage is necessary in order to realize coalbed methane(CBM) recovery because of the CBM development mechanism.The main production methods and their adjustability of CBM wells in China are analyzed in the paper.It points out that reasonable production system and carefully drainage control are the key factors to ensure production successfully,and un-continuity drainage,superfluous drainage intensity and rapidly depress bottom-hole flowing pressure(BHP) are the main engineering factors to influence CBM well... |
