【摘要】：正2017年7月14日,中国地质调查局组织专家对在贵州六盘水地区实施的杨煤参1井成果进行鉴定。杨煤参1井连续50天稳产煤层气3 600 m~3以上,最高日产气量达4 656 m~3,创下西南地区煤层气直井单井日产量新高和稳产日产气量新高,实现了我国煤系气(煤层气、页岩气、致密砂岩气)综合调查的重大突破。截至目前,该井已累计产气26.92×10~4 m~3,后期排采产量有望再上新台阶。据初步估算,杨煤参1井所在的杨梅树向斜煤系气地质资源丰度为4.79×10~8 m~3/km~2,煤系气资源量达366×10~8 m~3,比单纯的煤层气提高了6倍。
[Abstract]:On July 14, 2017, the China Geological Survey (CGS) organized experts to identify the results of well Yangtai 1 implemented in Liupanshui area, Guizhou Province. For 50 days in a row, Yangmaigan 1 well produced more than 3 600 mm3 of CBM, and the maximum daily gas production reached 4 656 mm3, which set a new high daily production of single well and a new high level of stable production of gas in single well of straight well of CBM in southwest China, thus realizing the realization of CBM (coalbed methane, shale gas) in China. A major breakthrough in comprehensive investigation of tight sandstone gas. Up to now, the gas production of this well has accumulated 26.92 脳 10 ~ (4) m ~ (-1) m ~ (3), which is expected to reach a new stage in the later stage. According to preliminary estimate, the abundance of gas resources in Yangmeishen syncline is 4.79 脳 10 ~ (-8) m ~ (-1) / 3 路km ~ (-2), and the amount of coal measure gas is 366 脳 10 ~ (8) m ~ (-3), which is 6 times higher than that of simple coalbed methane.
