摘要： A running tool is used to install a tubing hanger without entangling the continuous control lines. The tubing hanger running tool is made up of a central mandrel, an outer housing, a setting member, and an actuator. The mandrel has a lower end for securing to a tubing hanger. The outer housing surrounds the mandrel and is connected to the setting member. The actuator moves the setting member axially with respect to the mandrel so that the setting member can set the lock element on the tubing hanger, securing the tubing hanger to the tubing head. The setting member has openings which allow the control lines from the tubing hanger to be fed through to the outside of the running tool so that they are not entangled during the placement of the tubing hanger.

摘要： A running tool is disclosed to deliver tools downhole, preferably supported on a wireline. The running tool will not release the downhole tool before the desired depth is reached, even if an obstruction is encountered. The tool has the ability to release upon application of pressure in the wellbore. The tool features a floating piston with a pre-charged chamber on one side. Hydrostatic pressure acts on the opposite side of the floating piston as the running tool descends. When the downhole tool reaches its desired depth and becomes supported, slacking on the wireline traps the hydrostatic on one side of the floating piston. Applied wellbore pressure, acting on a release piston exposed to the trapped hydrostatic on its opposite side, shifts the release piston and releases the running tool from the downhole tool. On the way uphole, the trapped hydrostatic pressure is released.

摘要： A method for conveying a tool into a borehole with the use of a tool conveying apparatus includes deploying the tool conveying apparatus into the borehole, transmitting fluid through the tool conveying apparatus, the tool conveying apparatus generating power from the flow of fluid therethrough, discharging fluid from the tool conveying apparatus and providing power to at least one tool carried thereby. The tool conveying apparatus also includes a communication system for transmitting data bi-directionally between the tool and the surface.

摘要： A packer and method for sealing an annulus in a wellbore is provided. In one aspect the packer comprises a body having one or more conduits formed there-through; a chamber disposed within the body, wherein the chamber is in fluid communication with each of the one or more conduits; and an aperture for pressurizing the chamber. In another aspect, the packer comprises a body having one or more conduits formed there-through; a lock body disposed on a first end of the body; a collapsible member threadably engaged to the body at a first end and shouldered against the lock body at a second end; and a slideable member disposed within the collapsible member. In yet another aspect, the packer comprises a body having one or more conduits formed there-through, wherein the one or more conduits comprises an enlarged first end; and a cutting member disposed with the enlarged first end.

摘要： The present invention provides a drop ball sub that may be used to drop a large ball having an outer diameter larger than the inner diameter of a restriction in the wellbore such as the running tool used to run a first casing string through a second casing string. A smaller ball is used to control dropping of the large ball. The smaller ball has an outer diameter smaller than the restriction. The drop ball sub of the present invention may be used to operate any downhole tool that would benefit by receipt of a large ball. By dropping a larger ball, in one use of the invention larger valves can be controlled in the float equipment that provide a larger fluid flow path. A larger fluid flow path reduces surge pressure and enables the system to handle more debris. The present invention provides a system that preferably provides for a diverter tool above the running tool and a diverter tool below the running tool. The use of the upper diverter in conjunction with the lower diverter tool permits fluid flow into the second casing string to reduce back pressure and provide a large volume flow path.

摘要： A method of cementing a well permitting a reduction in the degree of diameter reduction of casing or liners required, and not requiring excessively large initial conductor casing, is described. The method is characterized by provision of an enlarged wellbore and a novel liner structure which is adapted for expansion of a reduced diameter section thereof downhole, providing, before expansion of the section, unimpeded flow of fluid from the enlarged wellbore during cementing and close fit of the expanded section with the casing or preceding liner, after cementing is completed and expansion of the section. A novel well liner structure and novel well liner expansion means are disclosed.

摘要： A method and apparatus for use with two or more hydraulic conduits deployed downhole reduces a number of penetrations required through a well bulkhead for a given number of fluid paths extending therethrough. In a described embodiment, a fluid conductor includes multiple fluid paths extending therein. The fluid conductor is installed in an aperture formed through a bulkhead. Couplings are connected on opposite sides of the bulkhead to opposite ends of the fluid conductor. Multiple hydraulic lines are connected to each of the couplings.

摘要： A system usable with a subterranean well includes a tubing and a lubricator. The tubing is adapted to receive a drill string in a passageway of the tubing, and the lubricator is located downhole and is connected to the tubing. The lubricator is adapted to be remotely operable from a surface of the well to control fluid communication between the passageway located above the lubricator and a formation located beneath the lubricator. The lubricator may include a sleeve and controller. The controller selectively moves the sleeve into a passageway of a valve of the lubricator to protect the valve from a downhole fluid.
