Research on the Application Effect of Top Drive Casing Technology in the East China Sea
In the process of offshore oil drilling operations,well cementing is one of the most risky links,directly related to the safety of downhole,reservoir development during the well completion process and the implementation of later increase production measures.Running casing is a crucial part of the well cementing construction program,and the quality of casing threading and whether the casing is smoothly lowered to the designed well depth have a significant impact on subsequent drilling.With the increasing difficulty of operating wells in oil drilling,the number of deep wells,ultra deep wells and extended reach wells is also increasing,the casing running operation of these high difficulty wells has become a great challenge.Top drive casing technology,as an emerging technology,is one of the important means to solve these problems.Therefore,this article provides a detailed introduction to the working principle,equipment features,operating methods and practical advantages and disadvantages of top drive casing technology,and proposes improvement suggestions to provide reference for the subsequent on-site use of top drive casing technology.
