摘要
为加快沁水盆地南部煤层气开发进程,针对煤层气多井、低压及低产的特点,中联煤层气有限责任公司采用"分片集输一级增压"的管网布置方式,对传统的集输工艺进行了改进优化,由1个简单阀组替代了集气站作为采气和集气的转换环节,同时引入GPRS移动无线数据传输技术,大大简化了集输流程,减少了生产设施,方便了运行管理,显著降低了工程投资,为沁水盆地南部煤层气田全面进入商业化开发奠定了坚实的基础,也为其他地区的煤层气开发利用提供了参考。
To accelerate the process of coalbed methane(CBM) gas development in the southern Qinshui Basin,the China United Coalbed Methane Company Limited has developed a new ground technology of per-well gas gathered by each individual fractional valve set to one centralized boosting station in the CBM Gas Field.According to the characteristics of multi-well,low pressure and low production in CBM gas production,the conventional ground technology was innovated and optimized to form this new technology.First,fractional valve sets are functioned as the previous gathering station to connect gas production lines and gas gathering lines.Second,the GPRS wireless communication technology is introduced to simplify the gas flow process from wellhead to the users through the centralized boosting station.With this new technology,unnecessary devices are reduced,the operation management becomes easy,and the engineering cost is cut down.This case history provides robust foundation for the commercial development of CBM gas fields in the Qinshui Basin and valuable reference for the CBM production and utilization in other similar fields in China.
