摘要:
An electronic recording device and multiple sensors for measuring various parameters at locations remote from the recording device. The multiple sensors can be joined together to comprise a downhole tool for measuring various parameters within a well bore and transmitting information concerning each parameter to the recording device via a single conductor electrical wireline. The embodiment disclosed within this patent measures the parameters of pressure, temperature, flow rate plus direction, and collar location. A wide variety of sensors can be included within the downhole tool to measure additional parameters as desired. This invention allows the multiple sensors to measure various parameters at any location remote from the recording device and to transmit information concerning each parameter to the recording device on single conductor electrical line as a composite signal.

A valve for automatically dumping a load of solids entrained within a fluid transport medium in response to flow interruption is disclosed. The automatic dump valve is particularly well-suited for use in combination with a module transport riser in deep ocean mining operations. The automatic dump valve system is combined with a tubular conduit defining a longitudinally extending flow passage having a sidewall opening defining a dump port. The automatic dump valve assemby includes a movable dump port cover plate and a hydraulic actuator coupled to the cover plate The hydraulic actuator is operably responsive to pressure changes within the flow passage relative to the pressure exerted by a surrounding body of water to open and close the dump port. The hydraulic actuator is formed by the combination of a sidewall portion of the tubular conduit constricting the flow passage thereby defining a venturi flow region, and a pressure chamber housing enclosing the conduit section and defining an annular pressure chamber. The pressure chamber is divided by a movable piston into a first chamber which is connected in fluid communication with the venturi passage, and a second pressure chamber which is exposed to hydraulic pressure exerted by the surrounding body of water. The dump valve further includes a deflector plate mounted within the tubular housing for movement from a clear passage position to a dump position, with the deflector plate extending from the dump port transversely through the flow passage in the dump position thereby defining a bypass channel for diverting settling solids through the dump port.
摘要:
A well packer for use in geothermal wells or stem injection wells. The packer can be anchored to the inner wall of a casing string to resist differential pressure in either direction. The anchoring means includes a single set of slip elements which are hydraulically or mechanically set. The packer includes a sealing unit with packing elements especially adapted for high temperature wells. The packer can be simply released from the casing by upward tension on the tubing.

Disclosed is an axially movable valve for admitting fluid to a fluid starved region. The admitted fluid feeds a pressure generating pump. Fluid pressure generated by the pump provides a force to further open the valve and to move a tool actuator. The valve opens with minimal sliding friction resistance. During the opening sequence, the flow area of the valve gradually increases. This abstract is neither intended to define the scope of the invention, which, of course, is measured by the claims, nor is it intended to limit the invention in any way.

A swivel connector for joining well tools or similar apparatus with a main longitudinal bore or passage through which well operations may be conducted and at least one separate passage for conducting fluid therethrough which extends through the swivel joint and is not blocked by rotation or pivoting of the swivel joint. This abstract is neither intended to define the invention of the application which, of course, is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.

Method and apparatus for producing and recovering solvent vapor for cleaning the interior surfaces of substantially sealed vessels and the exterior surfaces of structures contained therein]. In the illustrated embodiment, a transportable vessel cleaning system is disclosed. The system comprises a plurality of solvent vapor producing chambers, each having a solvent vapor outflow port and a solvent vapor inflow port coaxially arranged along a vapor flow axis extending through each chamber along flow channels associated with the solvent vapor outflow and inflow ports. When operationally configured with a substantially sealed vessel, each solvent vapor producing chamber of the present invention produces a solvent vapor stream which is recirculated through the vapor delivery tube, vessel interior, vapor recovery tube and the solvent vapor producing chamber along the direction of its vapor flow axis. Each recirculating solvent vapor stream facilitates heat and solvent vapor fluxes between the solvent vapor producing chamber and the vessel interior which are sufficient to maintain saturated solvent vapor in the vessel at very high temperatures during cleaning operations.
