摘要
晋城矿区当前煤层气开发的主要井型为直井,为满足不同地质条件下煤层气开发的需求,提高产气效率,将U型井作为一种重要的新型煤层气开发技术进行研究。分析了研究区地质条件和煤储层特征等因素,以晋城矿区赵庄区块SP-02井组为例,对其井位选择及钻完井技术进行了试验研究,实际监测表明,产气量明显提升,是赵庄区块产气量较大垂直井的4倍左右,产气效果理想。最后对U型井的开发提出了一些建议,为该技术的进一步推广应用提供借鉴和参考。
The major current mine type in Jincheng mining area are vertical shaft. In order to meet the demand of coalbed methane development under different geological conditions and improve the efficiency of gas production, take the U-shaped mines with new type of coalbed methane development technology as research objectives. The geo- logical conditions and characteristics of coal reservations in the targeted area are analyzed. Taking the SP-02 mines Jincheng mining area as an example, the mine location and drilling techniques are studied. The on site monitoring shows that gas production significantly improved, gas production is almost 4 times larger than the biggest vertical shaft mine in Zhaozhuang area, get the pegect effect. The paper puts forward some suggestions for the CBM development in U - shaped mine, also provides reference and reference for further popularization and application of the technology.
