摘要： 为准确获得吉UX井开采层位水力压裂裂缝的形态及方位，利用地面测斜仪水力压裂裂缝监测技术，对吉UX井9段开采层位进行水力压裂裂缝监测，获得了水力压裂裂缝的形态；利用真三轴水力压裂模拟系统，模拟吉县区块地应力状态，对煤岩进行了水力压裂模拟。监测和实验结果都表明，裂缝扩展以水平缝为主，用水平井在一个小层内压裂，纵向上难以有效沟通多个小层。据此认为，吉县区块采用水平井压裂沟通多个小层的开采方式，具有极大的投资风险。

Abstract: Accurate understanding of the hydraulic fracture morphology and orientation can be of significance for horizontal well deployment and fracturing design optimization. Nine sections of hydraulic fractures are monitored using tiltmeter, and the morphologies of them are obtained, followed by physical simulating in?situ stress state in this block and hydraulic fractures in CBM using true triaxial hydraulic fracturing simulation system. Monitoring and the experimental results show that the fracture propagation is dominated by horizontal fracture. To make hydraulic fracturing within one of the layers by horizontal well process is hard to shape effective connection of the multiple layers in longitudinal direction. It is concluded that such a process of horizontal well plus hydraulic fracturing to connect multiple layers in Jixian block has a great risk of investment
