四川煤层气勘探开发的现状、关键问题与建议

CBM Exploration and Exploitation Status,Key Issues and Proposals in Sichuan Province

四川省自2010年古蔺大村DCMT-3煤层气井组成功以来,尤其在2016年西南地区煤层气勘探与试验在局部地区取得了重大突破,获得了如杨梅参1井、川高参1井等高于4 000m3/d,最高达8 307m3/d的高产煤层气井,四川省有望成为全国煤层气重要的气源供给基地。总结四川地区高产气井的沉积环境研究,研究其成藏规律,加强煤层气选区、储层改造,对今后西南地区的煤层气勘探开发以资借鉴。

Since the 2010 successful construction of DCMT-3 CBM well group in Dacun Village, Gulin County, Sichuan Province, especially 2016 southwestern China CBM exploration and test has achieved major breakthrough in local areas. Drilled well YMC No.1, CGC No.1 etc high yield CBM wells with capacity above 4 000m^3/d, the maximum can be 8 307 m^3/d as high. The province is expected to become a national major CBM supply base. Summarized the area’s high yield CBM well sedimentary environmental study, studied its reservoiring pattern, to strengthen CBM well location selection, reservoir transformation, thus can provide reference for CBM exploration and exploitation in southwestern China henceforth.
