摘要
DFS-C02V井最大日产气量超过3万m^3,为彬长矿区乃至全国范围内的煤层气高产井之一,本文结合DFS-C02井组钻遇煤体结构、井眼轨迹、矿区掘进巷道和排采技术管理等方面影响因素,对DFS-C02V井高产原因进行分析,对煤层气多分支水平井开发方案设计、排采技术管理提供有效借鉴作用。
The maximum daily gas production of DFS-C02V wells is more than 30, 000 m3, which makes it become one of CBM wells with high production in Binchang Mining Area and even in China. This paper combines the influence factors, including the coal structure during drilling of DFS-C02 well group, well trajectory, excavation roadway and management of drainage technology management, analyzes the reason of high production of DFS-C02V well , which will provide effective references on the designing of multi-lateral horizontal well development plan and management of drainage technology.
