    摘要： An apparatus that is usable with a subterranean well includes a safety valve assembly and a pressure/temperature sensor. The safety valve assembly is controllable to selectively isolate a formation of a well from the surface of the well. The pressure/temperature sensor is located in the safety valve assembly to measure a pressure/temperature near the safety valve assembly.

    摘要： A gas lift valve has a flow restrictor, a valve part on one side of the flow restrictor, a flow deflector and a tubular member on another side of the flow restrictor, and a flapper valve on the side of the flow restrictor where the tubular member is located, the flapper valve being adjacent to the tubular member. When fluid flows into the gas lift valve at sufficient pressure, the valve part opens, the fluid flows through the flow restrictor and acts on the flow diverter thereby moving the tubular member and opening the flapper valve. The tubular member extends though the opening the flapper valve covered.

    摘要： A technique enables control over flow in a wellbore with a flow control system. The flow control system combines a flow reduction mechanism with a flow control device, such as a valve. The flow reduction mechanism comprises a closure member which can be selectively moved between an unactuated and actuated position, allowing relatively greater flow through the flow control device in the unactuated position. The flow reduction mechanism actuates prior to or in conjunction with the flow control device to reduce flow and thus reduce the loading forces that would otherwise act against the flow control mechanism upon closure of the flow control device.

    摘要： A fluid communication nipple including a tubular mandrel having an interior surface defining an internal bore and a passageway extending substantially lengthwise along a portion of the mandrel. The passageway is defined by an exterior wall section and an interior wall section, wherein the interior wall section extends outward from the interior surface into the bore. When it is desired to establish fluid communication through the passageway between the exterior and interior of the nipple an opening is formed through the internal wall section.
