摘要： The disclosure provides a goat head, as a mixing block, for multiple fluids in oilfield applications, the goat head having a reversing directional flow, mixing portion, wear reduction surfaces, and restricted outlet bore. The goat head provides an underneath approach for piping, reducing the overall height, and mixes the fluids dynamically within the goat head from angled flow paths. The goat head then reverses at least a component of the fluid flow direction that enters the wellbore below the goat head and exits the goat head into the well therebelow. The goat head to contains hardened wear surfaces, including surfaces in specific zones, to resist erosion caused by the reversing directional flow. A restricted outlet bore has a cross-sectional area that is less than the sum of cross-sectional areas of the inlets to assist in creating higher velocity and streamlined flow as the fluid exits the goat head.

摘要： The disclosure provides an adjustable modular skid system with a plurality of skid modules to support oil field fluid components, such as manifolds, mixing blocks, collection blocks, fracturing pumps, piping and connections, and other devices used to transport water, sand slurries, gas, oil, or other fluids in oil field applications. The skid system has vibration adjusting features. The skid modules can be coupled together through piping and relevant connections at the well site. If appropriate, the skid modules can be supported on pilings or other foundational supports. The system can be assembled remotely, started and tested, partially disassembled into the skid modules, and then installed at the well site with minimal additional effort by generally providing lines and connections between the modules. Excessive vibrations in the system can be reduced by adjusting an overall stiffness of the system to change a natural frequency of the system.

摘要： The disclosure provides one or more manifolds having manifold portions primarily of fluid conduit and flow components mounted to the manifold portions, such as valves and fluid fittings. The manifold is formed with a uniform bore, so that the manifold portions are the same size along the flow path of the manifold, and the valves and fluid fittings have a bore the same size of the bore of the manifold portions. The uni-bore manifold creates a less turbulent flow path and allows draining of the manifold through one or more valves coupled to an end of the manifold that otherwise can become restricted or plugged with particles entrained in fluids in the manifold.

摘要： The disclosure provides a Type U blowout preventer (BOP) that includes a body generally coupled with a set of bonnets. The bore of the body differs from conventional Type U BOPs. The bore of the body is formed with a contour that allows differential engagement with a ram having ram seals at different places along the bore. Further, the coupling between the bonnet and body can optionally be different from conventional Type U BOPs. In at least one embodiment, the bonnet is coupled to the body in conjunction with a tube holding an extraction shaft with a head held to the bonnet with a retainer. The tube and extraction shaft allows the bonnet to be removed from the body without hydraulic external force.

摘要： The disclosure provides a blowout preventer (BOP) system with a ram having a shear blade with a shear blade profile to shear a tubular member disposed in the BOP. The shear blade profile can include a stress concentrator and centering shaped surface. The stress concentrator and the centering shaped surface can be laterally offset from a centerline of ram travel and on opposite sides of the centerline. An opposing second shear blade can have a mirror image of the shear blade profile with the stress concentrator and centering shaped surface reversed to the orientation of the first shear blade. Further, the ram can include a mandrel with a mandrel profile for the tubular member to deform around during the shearing process and to reduce an overall lateral width of the sheared tubular member in the BOP through-bore to allow retrieval of the deformed sheared tubular member from the BOP.

摘要： The disclosure provides a choke with an actuator that contains various components within an actuator housing to adjust the choke, and the housing is configured to be fixedly attached with a relatively large shearing connection on an actuator adapter to resist large overpressure surges within the housing and around the components. The actuator further includes a thrust bearing mounted adjacent a shoulder in the housing and supporting a worm gear, so that any overpressure loads are directed to the shoulder of the housing and retained within the housing while the housing is retained by the shearing connection to the remainder of the choke.

摘要： A non-ported expanding gate valve and method of use, including an expanding gate assembly and a slotted guide, is fixedly positioned on the valve body and slidably coupled with a gate assembly. The guide has slots of varying widths that are used with a pivoting rocker arm coupled with the gate assembly to adjust the thickness of the gate assembly at the proper timing. The guides perform multiple functions, including: centralizing a rocker arm during opening between seats; collapsing the gate assembly when opening; allowing and controlling expansion when closing; guiding lateral movement during operation of the gate assembly between opposing guides on the sides of a flow passageway; guiding axial movement during operation of the gate assembly between opposing guide side flanges; retaining seats in position when the valve is open; and/or stiffening the guide in a lateral direction to control movement of the gate assembly.
