摘要： A safety valve apparatus has a housing with a bore and a projection disposed in the bore. A locking dog disposed on the housing is movable to engage an inner conduit wall surrounding the housing, and a flapper rotatably disposed on the housing is movable between opened and closed positions. A first sleeve disposed within the bore above the projection is mechanically movable between locked positions. In one locked position, the sleeve moves the locking dog to engage the wall. A piston disposed in the housing hydraulically communicates with a port in the projection and couples to a second sleeve disposed within the bore below the projection. The second sleeve conceals the piston and is hydraulically movable to open and close the flapper.

摘要： An apparatus for automatically closing a bottom safety valve in a pumped oil well in case of a cessation of pumping, and reopening the valve when pumping resumes. A conventional valve pump is installed in the production tube. A channel, which is connected to the production tube, passes through the valve body, and is blocked by a controllable flap. The valve body also contains a second channel, the two channels communicating by means of a cavity which is located upstream of the flap. A push rod slidably retained in the second channel is actuated by a piston for opening and closing the flap. A conduit connects the downstream portion of the production tube to an admission chamber and thereby transmits pressure to the piston; such that, when the downstream pressure of the valve pump is greater than that at the bottom of the well, the flap remains open; and when the difference in the pressures is reversed, the push rod causes the flap to close.

摘要： A communication arrangement is disclosed for communication between a downhole line and a wellhead body having a through-hole and a valve member for closing the through-hole. The communication arrangement provides a fluid passage that extends from a wellhead body port to the downhole line thus allowing communication between the wellhead body and a safety valve or valves and/or the injection of chemicals or fluids into the well without the need to rework the valve member or disable the valve member.

摘要： A safety valve apparatus has a housing with a bore and a projection in the bore. A flapper rotatably disposed on the housing is movable relative to the bore between opened and closed positions, and a packing element disposed on the housing is compressible to engage an inner conduit wall surrounding the housing. An upper sleeve disposed within the bore above the projection is hydraulically movable from a first position to a second position via the hydraulic communication with a port in the projection. The first sleeve when moved to the second position compresses the packing element. A piston disposed in the housing hydraulically communicates with the port and couples to a second sleeve disposed within the bore below the projection. The second sleeve conceals the piston and is hydraulically movable via the hydraulic communication of the port with the piston to open and close the flapper.

摘要： To deploy a capillary string through a wellhead to a downhole safety valve, a control port and a retention port are drilled in an adapter between a casing hanger and a gate valve or elsewhere. The capillary string is connected to a first port of a capillary hanger and installed through the wellhead. The capillary hanger is landed on a tubing hanger, and a side port on the capillary hanger communicates with the control port. Because the side port's location may not align with the control port, operators may need to measure how long the capillary hanger should be. A control line connects to the control port in the wellhead's side to communicate with the capillary line, and a retention rod inserts in the retention port to support the capillary hanger.
摘要翻译：为了将毛细管柱通过井口部署到井下安全阀，在套管悬挂器和闸阀或其他地方的适配器中钻出控制口和保持口。毛细管串连接到毛细管悬挂架的第一端口并通过井口安装。毛细管悬挂架落在管道悬挂架上，毛细管悬挂架上的侧面端口与控制端口相通。由于侧端口的位置可能与控制端口不一致，操作者可能需要测量毛细管悬挂架应该有多长时间。控制线连接到井口侧的控制端口以与毛细管线连通，并且保持杆插入保持口以支撑毛细管悬挂架。

摘要： Methods and apparatus for sealing a safety valve within a tubular that the safety valve is designed to be landed and set in are disclosed. The valve includes a seal assembly having a seal on the valve that is acted on by a first piston disposed on a first side of the seal and/or a second piston disposed on a second side of the seal. Wellbore fluid pressure acts on the first piston when the valve is closed, thereby moving the first piston to force the seal into sealing contact with an inside surface of the tubular. When the safety valve is actuated open, fluid pressure from a control line acts on the second piston and moves the second piston to force the seal into sealing contact with the inside surface of the tubular. The seal may include a plurality of chevron seals on each side of a sealing element.
