The invention provides a deep-water drilling water-secluding pipe kinetic parameter measurement system and method and relates to the technical field of offshore oil and natural gas drilling. The system comprises a deep-water drilling platform, a derrick arranged at the upper portion of the deep-water drilling platform and a deep-water drilling water-secluding pipe arranged at the lower portion of the deep-water drilling platform. The upper end of the deep-water drilling water-secluding pipe is connected with the lower end of a water-secluding pipe kinetic parameter measurement short section. The upper end of the water-secluding pipe kinetic parameter measurement short section is connected with a tension connector. The water-secluding pipe kinetic parameter measurement short section is used for measuring tensile stress, three-axis displacement and acceleration of the deep-water drilling water-secluding pipe and pressure and temperature in the water-secluding pipe. A satellite navigation mobile radio station device and a water-secluding pipe real-time monitoring and analysis workstation device are further arranged on the deep-water drilling platform. A Wi-Fi router in communicating connection with the water-secluding pipe kinetic parameter measurement short section, the satellite navigation mobile radio station device and the water-secluding pipe real-time monitoring and analysis workstation device respectively is arranged on the derrick.
Description
technical field [0001] The invention relates to the technical field of offshore oil and gas drilling, in particular to a system and method for measuring dynamic parameters of a deepwater drilling riser. Background technique [0002] At present, deepwater drilling risers are generally used in offshore oil and gas exploration and development operations as a channel connecting the drilling platform and the subsea wellhead. play an important role. Under the combined effects of random loads in the marine environment such as strong winds, waves, currents, and internal wave currents, drilling platform motion, and drill string-drilling fluid-riser coupling contact, deepwater drilling risers usually have deflection (e.g., maximum deflection The distance can exceed 100 meters), vibration, swing and other complex movements, and the stress state is very complicated and harsh. Because the deepwater drilling riser cannot withstand such a complex stress state, its service life is reduced...
