Physical simulation test system for subsea production facility hydraulic control system

Abstract

The invention discloses a physical simulation test system for a subsea production facility hydraulic control system. The physical simulation test system comprises a hydraulic power station, a hyperbaric cabin, an oil supply umbilical pipe, a subsea distribution module, a subsea control module, an actuator module, an oil return umbilical pipe, and a hyperbaric cabin oil return pipe, wherein the hydraulic power station is connected with the hyperbaric cabin and the oil supply umbilical pipe through a hyperbaric cabin oil supply pipe respectively; the oil supply umbilical pipe is connected with an inlet of the subsea distribution module; an outlet of the subsea distribution module is connected with the subsea control module and the actuator module respectively; the actuator module is connected with the oil return umbilical pipe which is connected with the hyperbaric cabin oil return pipe; the hyperbaric cabin oil return pipe is connected with the hydraulic power station; and parts are connected so as to form the physical simulation test system for the hydraulic control system. By a test platform of the subsea production facility hydraulic control system, the simulation and research of the whole subsea hydraulic control system in the actual engineering can be accurately finished.

Description

technical field [0001] The invention relates to a test system, in particular to a physical simulation test system for a hydraulic control system of an underwater production facility for performing a simulation test on the hydraulic control system of the underwater production facility. It belongs to the field of offshore oil engineering. Background technique [0002] At present, underwater production facilities mainly use hydraulic control to realize remote operation of underwater production. The hydraulic control system of underwater production facilities is mainly used to control the movement of the actuators of the Christmas tree on the underwater production facilities, and then control the switching of the gate valve of the Christmas tree and the downhole safety valve to complete crude oil transportation, chemical substance injection and safety production cut-off. [0003] The main components of the hydraulic control system are: hydraulic power unit HPU (Hydraulic Power ...

AI Technical Summary

Problems solved by technology

[0005] Due to the characteristics of high investment, high risk, and high output in offshore oil and gas development, it is too risky to place underwater hydraulic components directly on the seabed for testing. There are obvious differences in the test environment above, and different test environments have a great impact on the performance of underwater hydraulic components, which brings great inconvenience to the construction of the test system
