深水急紊流区水上钻探关键技术研究与应用
Research and application of key technologies for overwater drilling in deep turbulent zones
摘要
Abstract
Due to the influence of natural conditions such as water depth,offshore distance,wind and waves,overwater drilling has difficulties such as high construction difficulty,high risk factor,and low drilling efficiency.This paper combined the overwater exploration project of a hydropower station to conduct research and summary on the entire process drilling technology in deep and turbulent water areas,including the theoretical calculation of drilling platform outfitting specification parameters,also with the platform design,verification,and construction work suitable for overwater drilling in turbulent areas,and proposed a protective casing device and retraction process suitable for high flow velocity environments,which solved the problems of poor water flow impact resistance and low connection efficiency of casing under high flow velocity conditions in deep water.The above technologies ensure the safe and smooth implementation of drilling projects on turbulent water in the region,and the research results can provide a reference for overwater drilling in various industries or regions.关键词
