Hydraulic piston pump oil production system according to the power fluid circulation can be divided into open loop and closed loop two ways. In the open system (OPF), the power was taken out of the liquid are mixed together and back out of the ground; in a closed system (CPF),
portable fuel transfer pump and surface and underground movement, the force was circulated in a closed loop, not the recovery phase mix.
Open hydraulic piston pump piston pump hydraulic oil system closed production systems, ground gathering process, gathering and transportation processes open power fluid system, the process is more suitable for multi-well system, the jurisdiction of several members,
gas station management system dozens of wells.
