Description

technical field [0001] The invention relates to the technical field of deep-water drilling, in particular to a deep-water drilling riser and drill string wear simulation test device and test method. Background technique [0002] The development of deep-water oil and gas resources development technology is the key to the future development of offshore oil and gas resources. In the past 10 years, deep-water has become an important area of ​​the world's oil industry and the frontier of technological innovation. At present, 50% of the world's oil and gas resources growth comes from deep water. In the deep water area, 29 large oil and gas fields with more than 500 million barrels have been discovered. 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 The main replacement areas of global oil and gas resource reserves. [0003] The riser system is the key equip...

Problems solved by technology

The device and method are used to simulate the vibration characteristics of the riser model, so as to obtain the water-resistance model under different tensions, different water flow velocities, different drilling displacements, different drilling fluid densities, different drilling fluid viscosities, and different drilling speeds. However, this device and method cannot simulate the wear of the riser and drill string under different working conditions, nor can it effectively measure the wear amount of the worn part

[0006] At present, there are few studies on the wear problem of the riser and the drill string, and there is no test device and test method for the wear problem, but this problem will cause a major safety hazard to the safe operation of the riser, so it is urgently needed. A deepwater drilling riser and drill string wear simulation test device and test method, to deepen the experimental research on the riser and drill string wear, to ensure the safe and reliable operation of the riser
