摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
