煤层气井网布置的科学性、合理性对于提高煤层气产能和整体开发经济效益十分关键。首先，基于延川南区块煤层地质条件、试采分析，利用COMET3.0煤层气数值模拟软件，针对区块典型煤层气井开展历史拟合，校正该区煤储层地质参数。其次，在历史拟合基础上开展不同井网产能预测，确定了合理布井样式。最后，通过开展不同井间距的敏感性分析及经济评价的结果，最终确定该区合理的布井间距。合理开发井网参数的确定，为延川南区块整体井网方案的部署提供了科学指导。
煤層氣井網佈置的科學性、閤理性對于提高煤層氣產能和整體開髮經濟效益十分關鍵。首先，基于延川南區塊煤層地質條件、試採分析，利用COMET3.0煤層氣數值模擬軟件，針對區塊典型煤層氣井開展歷史擬閤，校正該區煤儲層地質參數。其次，在歷史擬閤基礎上開展不同井網產能預測，確定瞭閤理佈井樣式。最後，通過開展不同井間距的敏感性分析及經濟評價的結果，最終確定該區閤理的佈井間距。閤理開髮井網參數的確定，為延川南區塊整體井網方案的部署提供瞭科學指導。

Scientific and reasonable well pattern arrangement is a prerequisite for enhanced coalbed methane recovery and econom?ic development. Firstly, according to coal reservoir geological condition and pre-production analysis of South Yanchuan block, the historical fitting is proposed to modify the CBM reservoir geological parameters by using the numerical simulation software(COM?ET3.0). Secondly, by the production prediction of different well patten upon history simulation, the reasonable well pattern type is established. Finally, based on the sensitivety analysis and results of economic evaluation of different inter well distences, reason?able inter well distence in this block is determined. The determination of reasonable developed well patten parameters has great sci?entific guidence for the whole well pattern project of South Yanchuan block.
