    • A downhole recirculator for injecting two-phase lixiviant from a tubing string into a leaching interval of an in situ mine field injection hole, and for circulating the injected lixiviant within the leaching interval. The recirculator includes a core device which is adapted to be readily inserted or removed from its operating position in a fixture defining the upper limit of the leaching interval. The core device includes an induction valve arrangement whereby a primary flow of two-phase lixiviant supplied from the minefield surface by way of the tubing string induces a secondary flow of lixiviant from regions of the injection hole near the top of the leaching interval. The primary flow two-phase lixiviant is combined with the secondary flow lixiviant and injected to a region near the bottom of the leaching interval to establish a circulatory motion of lixiviant within the leaching interval.

    • A tool for capturing and retaining a pump down plug or ball which has been released from equipment above in a well bore, concealing the pump down plug from subsequent flow of fluid or other material through the tool, and diverting flow from a normal circulation port toward a bypass port through the tool. The pump down plug seats in, and closes, the circulation port, where the pump down plug is then retained by a tubular receptacle. Increased fluid pressure then shears the tool body loose from its housing, moving it downward to a position lower in the housing. This opens the path through which the pump down plug was released from above. A further pressure increase can be used to open the bypass port through the tool body. When the tool body is released from its first position, a diverter can close over the tubular receptacle and divert movement of fluid and other material away from the area of the circulation port and toward the bypass port.
    • 一种用于捕获和保持已经从井下的设备中释放的抽水塞或球的工具,从随后的流体或其它材料流通过工具隐藏泵下塞,并将流从正常循环端口转向 旁路端口通过该工具。 抽水塞插入和关闭循环端口,然后泵管塞被管状容器保持。 增加的流体压力然后将工具主体从其壳体上松开,将其向下移动到壳体中较低的位置。 这将打开从上方释放抽水塞的路径。 可以进一步增加压力以打开通过工具主体的旁路口。 当工具主体从其第一位置释放时,分流器可以关闭管状容器并且使流体和其它材料的移动远离循环端口的区域并且朝向旁路端口转移。

    • An apparatus and method for the completion of wells through a production tube includes a tool body having cement flow ports and pressure displaced port closure elements. A perforated mandrel tube concentrically aligned within the production tube is secured to said tool body at its upper end. Concentrically within the mandrel tube is a dart transport tube. The dart transport tube is releasably secured to the tool body by a set of locking dogs. A first dart plug is placed in the production tubing bore at the well surface to be pumped or allowed to gravitate onto a closure seat in the lower end of the of the transport tube. This seat closure allows the production tubing to be pressurized for setting well annulus packers and opening of a cement port closure sleeve. After the production tube has been set by cement pumped down the production tubing bore and through the cement flow port, a second dart plug is positioned atop the cement column in the production tube. A pumped column of water or other well working fluid sweeps most of the production tube cement column into the well annulus and lower end of the transport tube. The second dart plug lands against an upper bore seat in the transport tube to enable another pressure increase in the production tube fluid column. This next pressure increase shifts a sleeve piston that closes the cement flow ports and releases the transport tube locking dogs. With the locking dogs released, the transport tube falls to the end of the perforated mandrel and opens the mandrel perforations to formation fluid flow from the screens into the production tube bore. Residual cement remaining in the tube bore is all displaced into the transport tube and removed from the production flow path without drilling.
    • 通过生产管完成井的装置和方法包括具有水泥流动端口和压力移位的端口封闭元件的工具主体。 在生产管中同心对准的穿孔心轴管在其上端固定到所述工具主体。 心轴管内集中的是飞镖传送管。 飞镖传送管通过一组锁定爪可释放地固定到工具主体上。 第一个飞镖插头被放置在井表面的生产管道孔中,以被泵送或允许其被引导到运输管的下端中的封闭座上。 该座椅关闭允许生产管道被加压以设置井环封隔器和打开水泥端口封闭套筒。 在生产管已经通过水泥泵送到生产油管孔并通过水泥流动口之后,将第二个飞镖塞置于生产管中的水泥柱的顶部。 水泵或其他井下工作流体的泵柱将大部分生产管水泥柱扫入输送管的井环和下端。 第二飞镖插塞抵靠运输管中的上孔座,以使生产管流体柱能够进一步增加压力。 这个下一个压力增加使一个封闭水泥流动口的套筒活塞移动并释放输送管锁定爪。 随着释放的锁定爪,输送管落到穿孔心轴的端部并打开心轴穿孔以形成流体从筛网流入生产管孔。 留在管孔中的剩余水泥全部移入输送管中,并从生产流路中移除而不进行钻孔。

    • The invention is a well fluid production valve that is positioned downhole in a closed condition below an upper formation packer. The valve comprises a cylindrical mandrel having central bore flow connection with the upper bore of well fluid production tubing and coaxially aligned within the lower bore of the production tubing string. Flow port apertures through the mandrel wall provide well fluid flow paths between the mandrel O.D. and the bore I.D. of the lower production tubing. These flow ports are covered to close the valve by a sliding sleeve around the mandrel O.D. The sliding sleeve is spring biased to the open position but also secured at the closed valve position by an annular piston actuated sear mechanism. Actuation pressure for opening the valve to admit a flow of well fluids from the production zone is a predetermined differential between the well pressure above the packer, usually a function of the well depth, and the operator controlled pressure within attached production tubing. The formation pressure, which may be more or less than the corresponding head pressure, is isolated from the valve actuator and therefore does not contribute to the valve actuating pressure. A fluid pressure conduit is provided that transmits fluid pressure from a well annulus zone above the upper formation packer down past the packer to the upper face of the annular piston within an annular valve actuation cylinder. Production tubing bore pressure is routed to bear upon the lower face of the annular piston. Sufficient pressure differential on the annular piston displaces the sear piston from the sleeve holding position with the sear piston removed. The standing spring bias on the sleeve slides it along the mandrel O.D. to open the flow ports.
    • 本发明是在上部地层封隔器下方的封闭状态下定位在井下的良好流体生产阀。 阀包括圆柱形心轴,其具有与井流体产生管的上孔的中心孔流动连接并在生产油管柱的下孔内同轴对准。 通过心轴壁的流动口孔提供心轴O.D之间良好的流体流动路径。 和钻孔I.D. 的较低生产管道。 这些流动端口被覆盖以通过围绕心轴O.D的滑动套筒来关闭阀。 滑动套筒被弹簧偏置到打开位置,但也通过环形活塞致动的冲击机构在闭合的阀位置处固定。 用于打开阀以允许井流体从生产区域的流动的致动压力是在封隔器上方的井压力之间的预定差异,通常是井深度的函数以及附接的生产管道内的操作者控制的压力。 地层压力可能大于或小于对应的头部压力,与阀致动器隔离,因此不会对阀门致动压力有贡献。 提供了一种流体压力导管,其将来自上部地层封隔器上方的井环区域的流体压力向下传递到封隔器下方到环形阀致动缸内的环形活塞的上表面。 生产油管孔压力被承载在环形活塞的下表面上。 环形活塞上的足够的压差使塞子活塞从套筒保持位置移动,同时移除了塞子活塞。 套筒上的立起弹簧偏压沿芯棒OD滑动。 打开流量端口。
