摘要： A system and method are provided for direct connecting downhole control hydraulics through an oil field hanger, where the hanger is coupled to a wellhead, to hydraulic lines extending outside the wellhead. Further, the direct connection allows hydraulic system integrity with reduced contamination and leakage. Hydraulic tool ports, formed on the hanger, are coupled with hydraulic lines extending downward to a hydraulic tool. Side ports, formed in the hanger, are fluidicly coupled to the hydraulic tool ports. Hydraulic lines extending outside the wellhead are directly coupled with the side ports by accessing the side ports through access openings in the wellhead when the ports are aligned with the access openings. The system can still maintain pressure within internal spaces of the wellhead after the connection by sealing the access openings with flanges, where the hydraulic lines extend through openings in the flanges that are also sealed around the lines.

摘要： The disclosure provides an efficient design for a pressure rated oil field gate valve that meets the challenges of providing a quality product with minimal increase in price due to the design. It minimizes weight increase in the valve body over valves not meeting strict pressure specifications, due to strengthening ribs at strategic places without having to increase the overall body size as in commonplace in the industry. It provides redundancy of seals with minimal costs and no change in seat pockets over valves not capable of meeting the higher standards. It provides multiple shear points along a valve stem that can still allow a user to operate the valve from external to the valve bonnet. It further provides for additional sealing of the valve bonnet to the valve body by using elasticity in metal over long lengths to maintain a compression seal between the bonnet and the body.

摘要翻译： 本公开提供了一种用于压力额定油田闸阀的有效设计，其满足由于设计而以最小的价格增加提供优质产品的挑战。 由于在战略位置加强了肋骨，因此不会增加行业中常见的整体体积，从而使阀体的重量增加最小化，这些阀门不符合严格的压力规格。 它以最小的成本提供密封件的冗余，并且在不能达到更高标准的阀门上没有阀座的变化。 它沿着阀杆提供多个剪切点，这仍然允许使用者从阀门外部操作阀门。 它进一步提供了通过在长度上使用金属的弹性来保持阀盖和阀体之间的压缩密封件来将阀盖额外密封到阀体。

摘要： The disclosure provides an adjustable modular skid system with a plurality of skid modules having a frame 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 modules can be arranged in multiple configuration to fit a particular well site. The modules can include supply modules, transition modules, and distribution modules. 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.

摘要： The disclosure provides a blowout preventer (BOP) system with an actuator for opening and closing a ram. The actuator includes a locking system having a clutch piston to operate a clutch having ratcheting teeth. The locking system disengages the clutch prior to the ram opening and closing. The clutch piston has a first portion with a larger area than a second portion. A clutch fluid pressure acts on the first portion, and a closing fluid pressure acts on the second portion. This area difference in the clutch piston portions allows the clutch to be disengaged during closing operations, even when the closing fluid pressure is the same as the clutch fluid pressure and the clutch is biased engaged by a bias assembly. Further, closing fluid pressure is applied to lessen the load on the clutch ratcheting teeth, while the clutch fluid pressure is applied to unlock the clutch.

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 a collection block that aggregates multiple incoming flow lines and provides a consolidated outgoing flow path. The collection block can be remote from a given well that is being fractured to minimize safety risk in operations around the well. The collection block has dual capabilities of being connected to individual incoming flow lines as well as to manifold systems for distributing the out flowing fluids. The one or more inlets can be formed in the collection block at an offset to a centerline of a longitudinal bore through the collection block. In some to embodiments, frac trucks can connect along an extended connection zone that provides the fluids from the truck to the collection block.

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： The disclosure provides a non-ported expanding gate valve and method of use, including an expanding gate assembly and a slotted guide, 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.
