摘要： A method of expanding tubing comprises applying a varying fluid pressure across the wall of the tubing. The variation in pressure may be achieved by varying one or both of the fluid pressure within the tubing and the fluid pressure externally of the tubing. A body of varying volume may be located in a volume of fluid associated with the tubing. Alternatively, the volume of a body of fluid associated with the tubing may be varied by movement of a wall portion defining a boundary of the volume, which wall portion may be associated with an oscillator or a percussive or hammer device. In other embodiments a pressurised fluid source may be provided, and the fluid may be supplied at varying pressure from the source. An increase in pressure within the tubing may be accompanied by a reduction in pressure externally of the tubing.

摘要： A downhole apparatus (10; 10) for reducing rotational and linear friction between a downhole tool (100; 100) and/or a downhole tool string and the wall of a wellbore (B) includes an annular body portion (12; 12′) configured for location on a mandrel (102; 102′) of the downhole tool (102; 102′) and one or more rib portions (16; 16′) extending radially from the annular body portion (12; 12′), and configured to engage a wall of the wellbore (B), the annular body portion (12; 12′) and the one or more rib portions (16; 16′) are integrally formed. The annular body portion (12; 12′) is elastically reconfigurable between a first configuration in which the annular body portion (12; 12) defines a first inner diameter and a second configuration in which the annular body portion (12; 12′) defines a second inner diameter configuration, the second inner diameter being larger than the first inner diameter. The annular body portion (12; 12′) is elastically or plastically reconfigurable between the second configuration and a third configuration in which the annular body portion (12; 12) defines a third inner diameter, the third inner diameter being smaller than the second inner diameter.
