    摘要: A subsurface safety valve features no flow tube to operate the flapper and optionally an equalizing valve in the flapper, if used. It relies on magnetic force that is selectively created to draw the flapper to the open position. A torsion spring can close the valve when the field is removed. Optionally, the fields can be set up to pull and push the flapper open or to do either one. The optional equalizer valve can also be operated by a force field, preferably magnetic.

    摘要: A shape memory material is used for a power spring in a subsurface safety valve. The spring is sized for the force it will deliver when it goes past its transition temperature and reverts to an original shape. The force released by having the spring pass its transition temperature holds the valve closed against hydrostatic pressure. Since the force exerted by the spring does not increase as the valve opens less force is required to hold the valve in the open position, thus lowering opening pressure. The trigger to cross the transition temperature comes from the expected temperature of well fluids at the mounting position of the subsurface safety valve. Other downhole applications are anticipated.

    摘要: A downhole wet connect uses a bearing relation between materials to take advantage of the piezoelectric effect between them. Voltage is applied from the surface to the uphole pad which induces a voltage to be generated from the downhole pad to a storage device to store power for operating downhole equipment. The generated voltage can also be used as a real time power supply for downhole equipment. Alternatively, the generated voltage can be coded as a signal to downhole equipment to send date acquired downhole to the surface. The transmission of information is two way. Voltage input from the surface is stopped as downhole equipment sends a voltage based signal uphole for conversion by surface processors to capture the data. Alignment or downhole debris issues do not affect the transmission capability of the pads in the wet connect.

    摘要: A flow sensor is incorporated into a junk basket to sense a flow stoppage due to a plugged screen or plugged cuttings ports in a mill. The sensor triggers a signal to the surface to warn personnel that a problem exists before the equipment is damaged. The sensor signal to the surface can take a variety of forms including mud pulses, a detectable pressure buildup at the surface, electromagnetic energy, electrical signal on hard wire or radio signals in a wifi system to name a few options. Surface personnel can interrupt the signal to take corrective action that generally involves pulling out of the hole or reverse circulating to try to clear the screen or mill cuttings inlets. Other variables can be measured such as the volume or weight or rate of change of either and a signal can be sent to the surface corresponding to one of those variables to allow them to be detected at the surface in near real time.

    摘要: A sensor and transmitter is employed with a pressurized chamber of a downhole tool to be able to tell at a glance when the tool is delivered for service that it is properly charged. The sensor and transmitter can be integrated within the tool so as to be protected from damage during run in. While in service the sensor and transmitter can monitor pressure in real time and include a capability to send surface signals for real time monitoring of chamber pressures corrected for the service depth, temperature and density of the hydraulic fluid, for example. The signal can be acoustic through the control line or the annulus or delivered through a fiber optic cable or signal wire run in the hydraulic control line, an auxiliary line or through the annulus.

    摘要: Float equipment is constructed to have the check valve in an offset and/or skewed position with respect to the centerline of the tubular housing that is part of a string. The design is applicable to poppet type check valves as well as flapper type valves that are actuated with a flow tube. The off center and/or skewed position of the valve components allows the cutting structure on a drill bit, rather than the nozzle area on the bit bottom to make intimate contact with the valve components to accelerate the milling one of the assembly and the making of additional hole beyond the recently cemented string.

    摘要: A packer or plug features a main sealing element that swells after a delay long enough to get it into proper position. A sleeve eventually goes away to let the well fluids at the main sealing element to start the swelling process until contact with the surrounding tubular or the wellbore is established. Other sleeves that are disposed above and below the main sealing element preferably swell, but mainly in a longitudinal direction against the main sealing element to increase its contact pressure against the surrounding tubular or the wellbore. The longitudinally swelling members may also be covered to initiate their growth after the main sealing element has started or even completed its swelling action. The longitudinally swelling members can be constrained against radial growth to direct most or all of their swelling action longitudinally. Extrusion barriers above and below the main sealing element can optionally be used.

    摘要: A method of streamlining expansion of long lengths of tubulars or screen is disclosed. In one embodiment, the expansion assembly is coupled with a length of pipe that acts as a weight and has a length longer than the anticipated section to be expanded. There is a stinger that fits into the pipe above the anchor and a seal to maintain sealing contact despite the downhole advance of the expansion assembly following each stroke of the expansion device and advance of a swage. By sequentially applying and removing pressure, the desired length is expanded downhole. Alternatively, coiled tubing is connected to the expansion assembly and weights that are above it and is paid out into the well as the expansion assembly descends after each stroke.

    摘要: Thin wall sleeves are inserted into a well and expanded into sealing position to a surrounding tubular. Each sleeve has a ball seat. A zone is perforated after a sleeve is secured in position below the perforations. The ball is dropped onto the seat and pressure is built up to complete the fracturing. After all zones are perforated and fractured, the balls are removed, preferably by dissolving them and the thin walled sleeves are left in the tubular against which they have been expanded. Production can then begin from a selected zone. The objects can be of the same size for each sleeve. The sleeves can be run through tubing and into casing. Acid can be pumped to dissolve the objects.
