The fluid, usually oil, water, foam, or gelled fluid that transports the proppants during hydraulic fracturing. The fluid that transports gravel during gravel packing is also called carrying fluid.
在水力压裂期间输送支撑剂的流体，通常为油、水、泡沫或稠化液。在砾石充填期间输送砾石的流体也称为携带液。
Fluid end consists mainly of module, suction and discharge valve assembly, suction and discharge spring, suction and discharge pipe, plunger, packing, safety valve and pressure regulator, etc.
液力端主要由液缸、吸入、排出阀总成、吸入、排出弹簧、吸入管、柱塞、盘根、安全阀、稳压器等部件组成。
The packing efficiency decreases with the increase of gravel concentration in injected liquid, fluid loss to formation and gravel size.
充填效率随携砂液中砾石浓度、滤失量及砾石直径的增加而降低。
