摘要:
我国页岩气多分布在山区，不仅埋藏深、岩石抗张强度大，而且井场道路复杂、施工场地有限，所需开采压力、排量、时间均高于美国页岩气开采的技术要求，对压裂车的单机功率、压力、排量、通过性、自动化水平及可靠性有着更高的要求。针对国内页岩气压裂工艺的特点，分析了超高压页岩气压裂车开发需解决的技术难点，从2500型超高压页岩气压裂车的技术参数、结构特点、先进性及试验情况进行了研究，为解决我国页岩气开采对压裂车大功率、超高压、大排量和智能化的要求提供了技术支持。性能测试结果表明，2500型超高压页岩气压裂车设计合理，各项性能完全满足我国页岩气压裂开采要求。 China's shale gas is often distributed in the mountains, which is buried deeply and have strong tensile strength. The road of well site is complex and the construction site is limited. The requirements of mining pressure, displacement and time were higher than the requirements in American. So the power, pressure, output volume, automatic level and reliability of fracturing truck should be more focused. According to the characteristics of the domestic shale gas fracturing technology, the technical difficulties of the development of the ultra-high pressure shale gas pressure cracking vehicle are analyzed. The technical parameters, structural characteristics, advanced and experimental conditions 2500 UHP shale gas fracturing truck are researched. The technical support is provided for the development of the high power, ultra-high pressure, large displacement and intelligence of the fracturing vehicle. Performance test results show that the 2500 UHP shale gas fracturing truck has reasonable design, and the performance fully meet the requirements of the exploitation of shale gas fracturing.
