大型压裂施工装备的配置与连接

The Configuration and Connection of Large Fracturing Equipment

由于我国还没有针对大型压裂施工制定装备配置与连接规范,各工程服务商大多根据自身条件进行配置,无法达到经济安全作业要求。为此,在分析国内外大型压裂施工现状的基础上,结合国内外在非常规油气开发过程中所取得的经验以及国产压裂装备研制和台架试验中所取得的研究成果,从主体装备的选择与配置、施工参数的选择、配液与供砂以及地面高低压管汇的连接等方面,提出我国大型压裂装备施工配置方案以及地面管汇系统连接要求。

There are no specifications for equipment configuration and connection for large fracturing construction in China and service providers conduct the configuration according to their own conditions. The configuration cannot reach the requirement of economical and safe operations. Therefore, the paper analyzes the current situation of domestic and foreign fracturing construction, refers to the experience obtained in unconventional oil-gas development at home and abroad, and examines the research achievements of domestic fracturing equipment development and bench test. Then, it discusses the selection and configuration of main equipment, construction parameters selection, fracturing liquid preparing, sand supply and connection between low and high pressure manifolds on ground. Finally, it proposes the construction configuration scheme for large fracturing equipment in China and the connection requirement for ground manifold system.
