Mechanical typhoon avoidance behavior simulated test device and method for hard suspended marine riser of deepwater drilling platform

Abstract

The invention discloses a mechanical typhoon avoidance behavior simulated test device for a hard suspended marine riser of a deepwater drilling platform. The test device comprises a deepwater test pool (1) with a wave making system and a horizontal movement mechanism (2), a cylindrical linear guide rail (7) which is arranged vertically is fixed on a slide block A (6), the end surface of a slide block B (8) is provided with an L-shaped steel plate (9), a vertical plate of the L-shaped steel plate (9) is fixed to the slide block B (8) via a screw, and a tightening sleeve (10) is provided with locking screws (11) in the circumferential direction; and the test device further comprises a computer (21) and a control box (23) and a data collection box (22) connected with the computer (21), the control box (23) is connected with a servo motor (28), and the data collection box (22) is connected with a foil gauge, a three-component dynamometer and a fiber grating sensor (20). The test device and method have the advantages that the typhoon avoidance condition of the hard suspended marine riser of the deepwater drilling platform can be effectively and reliably simulated, the versatility is high, and a test result is stable and reliable.

Description

technical field [0001] The invention relates to the technical field of deepwater drilling, in particular to a simulation test device and a simulation test method for the mechanical behavior of hard-suspended riser avoidance platforms of deepwater drilling platforms. Background technique [0002] At present, 50% of the world's oil and gas resources growth comes from deep water, and 29 large oil and gas fields with more than 500 million barrels have been discovered in the deep water area. Major oil companies in the world have gradually shifted their strategic focus to the exploration and development of deep water oil and gas resources. Deep water has become a global The main replacement areas of oil and gas resources and reserves. [0003] However, my country's deepwater drilling technology is still in its infancy, and related technologies are monopolized by foreign companies, especially in the riser safety control technology. The riser system refers to the key equipment conn...
