Research and Application of 9-5/8 Retrievable Casing Drilling Technology
Combined with present situation of ShengLi oilfield drilling equipments and its matching tools,Drilling Technology Research Institute of ShengLi has carried out research on retrievable casing drilling technology,and made emphasis on the research of the retrievable BHA.Running/Retrieving tool of BHA,Locking device of BHA and Composite bits have been designed and completed.And the laboratory experiments of these key tools have been finished.The field experiments have been finished in He4-GX60 well and Xinl10-X16 well.The trial result has proven that the retrievable casing drilling device is simple in structure,the design is rational and it can meet the demand of field application.The construction technique of casing drilling is completely feasible,technical route is right,which satisfied with the field operation requirements.
