Application analysis of drill string compensator isolation valve upgrade
The drilling string compensation system is needed to compensate the heave of drilling string in the drilling operation of deepwater drilling platform.In the compensation system,the role of the isolation valve and its key,its main purpose is to quickly cut off the main hydraulic circuit of the compensation cylinder when the drill string is broken,to avoid the impact of high pressure gas to push the piston rod on the cylinder head and the sky car when the drill string is broken,to ensure the intrinsic safety of the compensation system and the traveling system,this paper mainly introduces the upgrade application of the isolation valve.By updating the more sensitive detection module,the safety of drill string compensator can be significantly improved,and some references can be provided for similar platform compensator upgrade.
