Abstract

The invention discloses key equipment applied to the pressure test operation of a deep sea oil and gas pipeline. The key equipment comprises a pressure test regulation and control system, a chemical agent injection system, a data collection and transmission system, a pressure maintaining control system, an auxiliary system, an immersed sea water filter, an underwater pressure testing pump, an underwater throttling and control system, an underwater flowmeter, an underwater pressure gage and a pressure sensor, wherein all above systems are designed according to the application of a water depth which is greater than 2000m, the requirements of underwater antiseptic materials are met, the above systems are connected through skid-mounted modules, and the above systems are externally provided with a protection frame of a frame type structure. By use of the key equipment, all underwater arrangement of pressure test operation equipment can be realized, the defects of more ground equipment, large space occupation, high input cost, more high-pressure potential safety hazards and the like in a conventional pigging operation are reduced, and pressure test operation efficiency of a deep water pipeline is improved.

Description

technical field [0001] The invention relates to the fields of offshore engineering and deep sea, in particular to a key device used in pressure test operations of deep sea oil and gas pipelines. Background technique [0002] The global deep-sea equipment technology is developing vigorously, technological innovations are emerging one after another, the operating water depth is more profound, and marine equipment is developing in the direction of automation, greening, integration, and intelligence. [0003] The deep sea is the "main battlefield" for future offshore oil development. Restricted by factors such as engineering equipment capability and technical level, the development water depth of my country's offshore oil and gas fields is temporarily concentrated within 300 meters. The workload is also increasing year by year. Newly laid submarine pipelines need to be pressure tested before they are put into production to ensure that the internal pressure of the submarine pipe...
