The invention discloses an injection and discharging recovery system applied to flow safety of a circulating pipeline, and belongs to the technical field of pipeline flow safety control. The system comprises a liquid injection system, a pressure stabilization gas injection system, a back pressure control system, a separation and collection system and a circulating system, wherein the liquid injection system, the pressure stabilization gas injection system and the back pressure control system are all connected with the circulating system through pipelines, and the pressure stabilization gas injection system and the back pressure control system are both connected with the separation and collection system through pipelines. According to the system, liquid phase multi-phase injection, gas-phase pressure stabilization injection and automatic constant-pressure gas supplementation can be realized, and meanwhile, gas-liquid separation, gas-phase recycling and environmental protection treatmentcan be further realized in the discharging process.
Description
technical field [0001] The invention relates to the technical field of pipeline flow safety control, in particular to an injection and discharge recovery system applied to circulation pipeline flow safety. Background technique [0002] As the development of offshore oil and gas fields develops into deep water areas, the laying of oil and gas transportation pipelines is crucial. However, in the low-temperature and high-pressure environment of deep water, natural gas hydrate is easily formed in the pipeline, which will cause pipeline blockage. Therefore, collecting and analyzing various data through experiments becomes the basis for solving this problem. At present, the injection and discharge system of the existing circulation pipeline can only achieve a small degree of gas-liquid multi-phase injection, and it is not enough in the recycling of experimental gas and liquid and environmental protection. Contents of the invention [0003] In order to solve the defects in the p...
