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 to become restricted or plugged with particles entrained in fluids in the manifold.

摘要翻译： 本公开提供了一个或多个歧管，其具有主要由流体导管和安装到歧管部分（例如阀和流体配件）的流动部件的歧管部分。 歧管形成有均匀的孔，使得歧管部分沿着歧管的流动路径具有相同的尺寸，并且阀和流体配件具有与歧管部分的孔相同尺寸的孔。 单孔歧管产生较少的湍流流动路径，并且允许歧管通过联接到歧管的端部的一个或多个阀排出，否则阀可以被夹带在歧管中的流体中的颗粒被限制或堵塞。

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 fracturing isolation sleeve for a wellhead assembly including a fracturing adapter and tubing head. In at least one embodiment, the sleeve can telescopic to different lengths to fit different assemblies without necessitating switching the sleeve or portions thereof. The sleeve can be coupled to the wellhead assembly by threaded and non-threaded connections. The sleeve upper portion can be threadably engaged with the wellhead assembly, and/or the sleeve lower portion can be threadably engaged with a packoff bushing rotationally coupled to the wellhead assembly through an anti-rotation mechanism. Further, the sleeve can include a retaining nut to be threadably engaged with the wellhead assembly without necessarily rotating the sleeve upper or lower portions. The sleeve can be also coupled with the wellhead assembly through a mandrel coupled to the sleeve having an actuating cam surface to actuate a lock ring with the wellhead assembly.

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： A connector to secure a blow out preventer to tubing or a casing head of a well or wellhead and a method of securing a blow out preventer to the well utilizing the connector. The connector may be configured to secure the blow out preventer adapter to the wellhead and provide, within fifteen minutes, a seal operable to withstand ten thousand pounds per square inch of pressure. The connector may include both a hydraulically operated locking segment and a separate mechanical locking segment, and wherein both locking segments may be transitioned from a fully retracted position to a fully locked position within fifteen minutes. The connector may be configured to accommodate up to ten degrees of misalignment between the blow out preventer and the tubing.

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。
