Simulation platform device and method for wellhead environment of deepwater oil and gas production system

Abstract

The invention discloses a simulation platform device and method for the wellhead environment of a deepwater oil and gas production system. The simulation platform device comprises an adsorption cavitymain body, a middle flat plate above the adsorption cavity main body, a supporting frame mounted on the middle flat plate, an upper installation flat plate is installed at the top of the supporting frame, a plurality of channel pipes distributed along the edge of the upper installation flat plate and at least two rows of discharging pipes located close to the inside penetrate through the supporting frame and the middle flat plate vertically and downwards from the top of the upper installation flat plate until communicating within an adsorption cavity, and a wellhead simulation pipe penetratesthrough the supporting frame vertically and downwards from the top of the upper installation flat plate until reaching the middle flat plate. According to the simulation platform device, the seabed adsorption force can be designed according to the requirements, the construction difficulty of underwater layout can be reduced, the underwater installation and test conditions can be vividly stimulated, the adjustment of the levelness of the platform can be facilitated to meet the requirements, in time recovery can be achieved after the completion of the test, and the test difficulties of domesticunderwater oil and gas equipment can be effectively solved.

Description

technical field [0001] The invention relates to the application field of underwater installation, detection and verification of underwater oil and gas production system equipment, in particular to a wellhead environment simulation platform device and a simulation method for a deep water oil and gas production system. Background technique [0002] At present, my country's offshore oil and gas resource exploitation experience is about 300m, and greater water depth requires cooperation with foreign countries, and key equipment and supporting parts are all imported. It invested in the construction of a number of 3,000m-class engineering ships such as Offshore Oil 286, Offshore Oil 289, Offshore Oil 291, and 981 and 982 drilling ships. At the same time, the Ministry of Science and Technology, the Development and Reform Commission, the Ministry of Industry and Information Technology and related industry units have invested in the development of equipment and supporting components r...

Problems solved by technology

At the same time, the Ministry of Science and Technology, the Development and Reform Commission, the Ministry of Industry and Information Technology and related industry units have invested in the development of equipment and supporting components related to deep-water oil and gas production systems, such as Christmas trees, blowout preventers, manifolds, risers, underwater connectors and controllers, etc., which are currently in existence. There are problems such as the lack of inspection and test methods for marine engineering equipment and the lack of standardized means. After efforts to establish some test methods and process equipment such as land and pools, there are still insufficient supporting facilities, and it is impossible to carry out deep-water installation, commissioning process verification, and operating conditions. Experiments, resulting in the development of equipment can not be put into use
