Underwater test tree test system for deepwater oil and gas test

Abstract

The invention discloses an underwater test tree test system for the deepwater oil and gas test. The test system includes a stroke control module, a subsea high pressure simulation cabin, a gantry module, an electrical signal control module, a hydraulic control module, a connection positioning function test module, a time test module, a temperature and pressure test module, a chemical reagent injection test module and a positive pressure pumping test module. The test system is advantaged in that the wellhead condition simulation of deepwater test operation is achieved, functions and characteristics of underwater test trees in different models and structures, such as release tie-back, positioning guide, failure protection, positive pressure pumping, shut-off time, chemical injection, steel wire and continuous pipe cutting and temperature and pressure monitoring are achieved, a test platform is provided for design and optimization of underwater test tree prototypes, practicality and feasibility of new products are guaranteed, overall research and development efficiency are improved, the test platform can be provided for maintenance and repair of the underwater test tree products, andthereby safety and reliability in the application process are better guaranteed.

Description

technical field [0001] The invention relates to the field of deep-water oil and gas testing, in particular to an underwater testing tree test system for deep-water oil and gas testing. Background technique [0002] For a long time, my country's offshore oil and gas well testing has mainly relied on foreign technology, or purchased foreign testing tools and instruments, or directly asked foreign companies to complete it, which not only consumed a lot of foreign exchange, but also restricted the development of my country's oil and gas deep-sea well testing technology and related fields. Therefore, it is of great significance to carry out the research on the related systems and equipment of deepwater oil and gas well testing for the development of deepwater offshore oil in my country. As the most critical equipment for testing deepwater oil and gas wells, the research work on underwater test trees has been closely watched by offshore oil and gas exploration personnel. [0003]...
