摘要： Gas lift valve designs and gas lift systems are described that feature a positive closure mechanism that is highly resistant to significant wear or damage that would result in fluid leakage. A pivotable flapper member is incorporated into a gas lift valve and used as a flow control mechanism. The flapper member provides a positive barrier to fluid flow from the production tubing to the annulus, even after substantial wear or damage.
摘要翻译：描述了气体提升阀设计和气举系统，其特征在于具有高度抵抗将导致流体泄漏的显着磨损或损坏的积极闭合机构。可枢转的挡板构件结合到气举阀中并用作流量控制机构。挡板构件即使在大量磨损或损坏之后，也能从生产管道向环形空间提供积极的阻挡。

摘要： An insert device can straddle an existing production string port into the annulus such as through an open sliding sleeve so that annulus access into the production string is available. An injection string is associated with the insert to allow placement of the injection fluid at the desired location even if that location is below an isolation packer. The port can be part of an existing ported sub such as a sliding sleeve. Alternatively, the port can be created at a desired location and the insert supported with an anchor so that spaced seals straddle the port that is created to allow injection access from the annulus into the production tubing. The produced fluids pass around the injection tubing and through the insert body to get to the surface. The insert can be removed if needed.
摘要翻译：插入装置可以将现有的生产线端口跨越环形空间，例如通过开放的滑动套筒，使得环形进入生产线的通道是可用的。喷射柱与插入件相关联，以允许将喷射流体放置在期望的位置，即使该位置在隔离封隔器下方。该端口可以是现有移动子系统的一部分，例如滑动套管。或者，可以在期望的位置处形成端口，并且插入件用锚固件支撑，使得间隔开的密封件跨越所形成的端口，以允许从环形空间进入生产管道的注入。所产生的流体通过注射管道并穿过插入物体到达表面。如果需要，可以将插入物移除。

摘要： A plunger for use in downhole tubulars in wells which produce fluids and/or gases under variable pressure, which has an internal passage to facilitate more rapid descent of the plunger to the well bottom or well stop. The plunger has a stopper housed inside a chamber that is actuated when the plunger and stopper stem reach bottom or a well stop and which is held in a closed position by the build up of pressure below the plunger. The plunger may also have a jacket mounted about a core which has sealing, holding, and lifting capabilities. The plunger may also have fingers which project inwardly from the underside of the jacket toward the inner core which may also be grooved and which provides an inner turbulent or labyrinth-type seal.
摘要翻译：用于在井中产生流体和/或气体的井下管中的柱塞，其具有可变压力的内部通道，以促进柱塞更快地下降到井底或井停止。柱塞具有容纳在室内的止动件，当柱塞和止动杆到达底部或井止动件时，该止动器被致动，并且通过在柱塞下方的压力增加而保持在关闭位置。柱塞还可以具有围绕具有密封，保持和提升能力的芯安装的护套。柱塞还可以具有从护套的下侧向内突出的指向内芯的指状物，内芯也可以是开槽的并且提供内部湍流或迷宫式密封。

摘要： A plunger for use in tubulars in wells which produce fluids and/or gases under variable pressure. The plunger has at least two separate jackets comprised of segments mounted about one body or bodies joined by a connector, which collectively have increased sealing, holding, and lifting capabilities. A inner turbulent or labyrinth-type seal is accomplished by circumferential grooves on the core and/or fingers which project inwardly from the underside of the segments. The plunger body may also have an internal passage to facilitate more rapid descent, and a simplified stopper housed inside a chamber which is actuated when the plunger reaches a well stop or well bottom and which is held in a closed position by the build up of pressure below the plunger. When the pressure inside the tubulars above the plunger is reduced, the plunger and fluids move upwardly to the surface.

摘要： One or more control lines or other types of lines can be run past a downhole tool such as a side pocket mandrel, for example, in a longitudinal groove with a retaining feature for the control line where the assembly leaves little to stick out and get damaged on run in or on pulling out of the hole. In the preferred version, the groove is a dovetail and at least one retainer can be slipped into the dovetail. Lateral bores into the dovetail allow pins to be driven into a wedge shaped retainer to force it against the control line or lines such that the shape of the dovetail and the shape of the wedge retainer trap the control line within the dovetail. Upon assembly, nothing sticks out from the dovetail or the downhole tool.
摘要翻译：一个或多个控制线或其他类型的线可以经过诸如侧袋心轴的井下工具，例如在纵向凹槽中，具有用于控制线的保持特征，其中组件几乎不突出并被损坏在从洞中拔出时或从中拔出。在优选的形式中，槽是燕尾形的，并且至少一个保持器可以滑入燕尾榫。侧向钻入燕尾榫允许销被驱动到楔形保持器中以迫使其抵靠控制线或线，使得燕尾形的形状和楔形保持器的形状将控制线捕获在燕尾榫内。组装后，没有从燕尾或井下工具伸出。

摘要： In systems and methods for production of hydrocarbons fluids from a formation surrounding a wellbore, a production assembly is cemented into place, and excess cement is then cleaned from the production tubing and liner. Thereafter, hydrocarbon fluids are produced and artificial gas lift assistance is provided. All of this may be accomplished in a single trip (mono-trip) of the production tubing.
