煤矿井下治理瓦斯的水压致裂工艺的研究进展及展望

Research Progress and Prospect of Gas Control with Hydraulic Fracturing in Coal Mine

基于前期研究和文献调研,介绍了煤矿井下治理瓦斯的4种水压致裂工艺(常规水压致裂、定向水压致裂、脉冲水压致裂和吞吐压裂)的特点和应用实例。最后,对煤矿井下水压致裂治理瓦斯进行了展望:引入体积压裂思想,采用多种技术耦合增透,压裂液的选用与研制。

Based on the previous studies and literature review, the characteristics and application of four hydraulic fracturing technologies （conventional hydraulic fracturing, directional hydraulic fracturing, pulsed hydraulic fracturing and huff hydraulic fracturing） for gas control in coal mine were introduced.At last, the development prospects were proposed： introducing the idea of volume fracturing, improving the permeability of coal seams by multiple technologies, selection and study of fracturing fluid.
