Research on the Technology of Tail Pipe Rotating Insertion in Bohai Oilfield
With the continuous deepening of petroleum exploration,there are more and more cementing operations for large displacement wells.Due to the influence of factors such as large well displacement,large well inclination and long open hole section,there are difficulties in casing insertion.When encountering blockages,it increases the difficulty of lifting and increases the risk of cementing operations.Therefore,establishing a safe and effective tail pipe insertion process technology has become an urgent task.This article analyzes the advantages,required conditions and safety precautions of tail pipe rotation insertion,and introduces the practical application and economic benefits of tail pipe rotation insertion technology.From this,it can be concluded that the matching technology of tail pipe rotation insertion can meet the needs of special well conditions of Bohai offshore drilling technology and large displacement cementing.
