    摘要: The present invention generally provides apparatus and methods for reducing the pressure of a circulating fluid in a wellbore. In one aspect of the invention an ECD (equivalent circulation density) reduction tool provides a means for drilling extended reach deep (ERD) wells with heavyweight drilling fluids by minimizing the effect of friction head on bottomhole pressure so that circulating density of the fluid is close to its actual density. With an ECD reduction tool located in the upper section of the well, the friction head is substantially reduced, which substantially reduces chances of fracturing a formation.

    摘要: Disclosed herein is a device that relates to an actuator comprising a plurality of individual piston chambers pressurized by a common pressure source. A plurality of pistons are in operable communication with the piston chambers, the pistons each being in operable communication with an actuatable device, such that the plurality of pistons simultaneously act upon the actuatable device upon application of pressure to the plurality of piston chambers.

    摘要: A deformable member can be used in a well tool for use in downhole oil/gas wells. In one embodiment, a deformable member is described which is deformable between undeformed and deformed positions, and comprises a generally hollow cylindrical body defining a wall. The wall includes three circumferential lines of weakness in the form of grooves, with two grooves provided in an outer surface of the member wall and the other groove provided in an inner surface. The member is deformed outwardly by folding about the lines of weakness and is used in particular to obtain sealing contact with a tube in which the member is located.

    摘要: An apparatus and method for generating a drive force in a downhole environment includes chambers of a reactant and a catalyst, respectively, that are maintained separate until selectively exposed to one another. Once exposed, the reactant and catalyst produce expanding fluid pressure and sometimes heat. The products of the reaction are directed to a drive member to carry out a desired operation in the downhole environment.
