摘要： Two sliding sleeves (14 and 20) are carried in a tubular pipe assembly (10) for controlling the opening and closing of flow passages (12) through the pipe wall (13). The assembly (10) is placed at the lower end of a tubing string to regulate the flow of fluid from the string into a subsurface well formation. The first sleeve (14) extends between upper and lower seals (15 and 16) disposed above and below the flow passage (12) to close the flow passages (12) to flow. A shifting tool, operated from the well surface, moves the sleeve (14) axially down the assembly (10) to open the flow passages (12), leaving the upper seal (15) exposed. A shifting tool then moves the second sleeve (20) axially down the assembly (10) to cover the exposed seal (15). Fluid pumped through the assembly (10) exits through the flow passages (12) without having to flow through radial flow passages in the sliding sleeve. The two sleeve sections (14 and 20) protect the upper and lower seals (15 and 16) and sealing surfaces from fluid erosion.

摘要： The surface areas available for absorbing compressive loading of a threaded connection (30) are increased by increasing the engaged area of a torque shoulder (35) in the connection (30) and by reducing the spacing between the stab flanks of the threads (33, 34). The areas are increased by increasing the dimensions of the components and by decreasing the machine tolerances permitted in manufacturing the components. The gap (x) in the connection adjacent the torque shoulder is reduced so that the contact surface area of the torque shoulder is increased while the close proximity of the surrounding cylindrical walls of the connection reduces voids that can receive plastic deformation of the torque shoulder corners. The surfaces adjacent the torque shoulder are cylindrical (37, 38) in shape rather than being tapered to reduce machining costs and increase the speed of manufacture of the connection.

摘要： The invention concerns a flare gas recovery system comprising a flare gas source suitable for discharging a multi-phase stream including materials in two or more thermodynamic phases such as natural gas (NG), natural gas liquids (NGLs) and/or water, a separator suitable for separating thermodynamic phases of an incoming fluid, an ejector configured to increase the pressure of the multi-phase stream and a membrane system configured to further separate gaseous fluid discharged from the separator. The invention also concerns a method using such a flare gas recovery system.

摘要： A coupling (10) for a threaded and coupled connector used to secure the ends of the tubular pipe sections together comprising a tubular coupling body (11) with axially extending, internally threaded areas (11a, 11b) at each end of the body (11). Tapering external surfaces (11h, 11f) are formed on the body (11) which extend from a central portion of the body (11) toward each end of the body (11) and reduce in diameter in an axial direction from the central portion. The taper length (11h, 11f) is functionally related to the minimum outside diameter of a pipe section (12) to which the coupling is to connect.

摘要： A heavy weight drill pipe member is disclosed for use in drilling high angle and horizontal well bores in a corrosive environment. The heavy weight drill pipe member consists of a tubular member (10) with a longitudinal bore (29) therethrough, and includes connectors or tool joints (20, 22) attached at each distal end for connecting additional heavy weight drill pipe members. The tubular member (10) and tool joints (20, 22) are preheated, water quenched and tempered to obtain a unique combination of hardness, a yield strength and impact strength for improved resistance to stress corrosion cracking and hydrogen embrittlement in a hydrogen sulfide environment. The tubular member (10) includes a plurality of wear pads or protectors (12, 14, 16) equidistantly spaced along the longitudinal axis of the tubular member (10) to reduce bending stress in the pipe by limiting the degree of bend when the pipe is placed in compression in a high angle well bore. To reduce the chances of differential pressure sticking of the pipe when the pipe is used in high angle or horizontal well bores, each wear pad or protector (12, 14, 16) is provided with spiral grooves (24) therein. Each wear pad or protector (12, 14, 16) may also be hard faced or hard banded to reduce wear.
