阜新市刘家区煤层气开发利用现状

Current Status of Coalbed Methane Development and Utilization in Liujia Disctrict of Fuxin City

1998～2002年,东北煤田地质局一○七勘探队在辽宁省阜新市刘家区进行煤层气普查工作,施工的8口煤层气地面垂直钻井均获成功,单井日产量最高达7000m3,平均在3000m3左右,甲烷浓度达98%左右。2003年3月1日,阜新市刘家区煤层气地面开采项目正式向阜新市区供气,实现了煤层气商业性开发。本文根据刘家区煤层气资源普查及地面开采的实际情况,对其煤层气地质条件及开发利用现状作了论述。

During the Coalbed methane （CBM） general survey conducted by No. 107 Prospecting Team of Northeast Coal Geological Bureau in Liujia District of Fuxin City from 1998 to 2002, 8 CBM vertical wells was successfully constructed. The maximum daily output per well reached 7000m3 with an average output of3000m3, and the methane concentration is about 98%. On 1 March, 2003, the CBM sur- face development project in Liujia District started the gas supply to Fuxin City, which realized CBM commercial development. According to the results of the CBM general survey in Liujia District and the actual situation of CBM surface development, the paper discusses the CBM geological conditions in Liujia District and the present situation of development and utilization.
