摘要
以分段水力压裂封孔器的设计原则为依据,对封孔器的研发开展了有益探索,研制出了煤矿井下封压一体化分段水力压裂封孔器,并详细阐述了该封孔器的整体结构和关键部位设计,重点分析了封孔器的工作原理及其主要特点。
Based on the design principle of the sealing instrument for sectional hydraulic fracturing, and did something good for the research of sealing instrument. The integrated hydraulic fracturing and sealing instrument of the underground coal mine is developed. Described the whole structure and the key parts design of the sealing instrument in detailed, and emphatically analyzed the working principle and main characteristics of the sealing device.
