库拜煤田高陡地层煤层气勘探开发实践探究

Practical Exploration and Development of Coalbed Methane in High and Steep Strata in Kubai Coalfield

摘要: 库拜煤田位于天山南山麓，塔里木盆地北缘，由于地层塑性及应力释放等原因，区内构造复杂，地层倾角及倾向变化快，煤层展布难以摸清，在复杂构造带缺乏地质资料及少量钻井资料的前提下，开展煤矿瓦斯治理及煤层气勘探开发在国内基本上处于空白领域，亚新煤层气集团在如此条件下为保障区内煤层气勘探开发，积极开展研究，不断尝试积累经验，最终总结出适合区块煤层气勘探开发特色技术和方法。

Abstract: The Kubai coalfield is located in the southern foothills of the Tianshan Mountains, on the northern margin of the Tarim Basin. Complex formation plasticity and stress release have produced a structurally intricate zone where bed-dip and dip direction change rapidly, so the spatial distribution of coal seams remains hard to pin down. With sparse geological data and only a handful of wells in these intricate structural belts, the exploration and development of coalbed methane in the area were virtually uncharted territory in China. Undeterred, Asia CBM Group launched a dedicated research campaign, testing and refining its approach step by step. Finally, the characteristic technologies and methods suitable for the exploration and development of coalbed methane in the block are summarized.
