| Abstract: | Pipe sticking has been one of serious drilling problem in oil exploration in west China, such as in Tarim oil field. Major affords have been made to determine the causes of stuck pipe and to outline operating practices, but it produced a little effect. In this paper the author describes a system based on improved torque drag model for real time monitoring of wellbore friction in deep vertical wells only using surface measurements logged by a computer system. The curve of wellbore friction can give the early pipe sticking trend. With drilling engineering variables and mud property, it can forecast and prevent the occurrence of stuck pipe. |
