摘要： A fluid flow control apparatus, shifting tool and method for oil and gas wells in which a sliding sleeve valve is connected in a string of well tubing in a wellbore casing. The sliding sleeve valve functions to selectively control fluid communication between the well tubing and the wellbore casing. A shifting tool is provided for opening and closing the sliding sleeve valve and is connected to reeled tubing for receiving a fluid. The shifting tool includes a nozzle for discharging the fluid into the well tubing during or after the valve shifting operation.

摘要： A running tool for use with reeled tubing and a method of operating same in which a piston assembly extending over a portion of an inner mandrel assembly and in engagement with a locking device. Shear pins connect the piston assembly relative to the inner mandrel assembly and a fluid chamber is defined by cooperating shoulders formed on the inner mandrel assembly and the piston assembly. The inner mandrel assembly has a bore which can be connected to the fluid chamber for establishing fluid pressure in the fluid chamber to exert oppositely directed forces on the shoulder to shear the shear pins in response to a predetermined value of the fluid pressure to permit axial movement of the piston assembly to actuate the locking device.

摘要： An actuator and method for setting a subterranean tool uses an externally mounted actuator on a tubular string that is operably engaged to the tool to be actuated. At the desired location for actuation a signal is given to a valve assembly. The opening of the valve releases the pressurized compressible fluid against a floating piston. The piston drives viscous fluid ahead of itself through the now open valve that in turn drives an actuating piston whose movement sets the tool. The triggering mechanism to open the valve can be a variety of methods including an acoustic signal, a vibration signal, a change in magnetic field, or elastic deformation of the tubular wall adjacent the valve assembly.

摘要： A pulling tool and method for pulling an operating tool from a downhole location in a wellbore in which an elongated tubular housing assembly is connectable to a section of reeled tubing and defines a longitudinal bore through which fluid passes from said reeled tubing. A passage extends through the housing assembly and communicates with the longitudinal bore of the housing assembly for discharging the fluid against the wall of the wellbore and the fishing neck of the operating tool to clean same. A latching assembly is disposed on the housing assembly for latching to the fishing neck of the operating tool as the housing assembly is inserted into the fishing neck to enable the fishing neck and the operating tool to be pulled from the wellbore. In the event the operating tool cannot be pulled from the wellbore, the flow of fluid through the passage of the housing assembly can be blocked to enable the fluid pressure to build up in the bore of the housing assembly, in which case the housing assembly operates to release the fishing neck to enable the housing assembly to be removed from the wellbore.

摘要： A fluid flow control system, assembly and method for wells in which a sliding sleeve valve is connected in a string of well tubing in a wellbore casing. The sliding sleeve valve functions to selectively control the lateral flow of fluid through the assembly into the annulus between the assembly and the wellbore casing. A straddle assembly is locked within the sleeve valve assembly for isolating a lateral flow path. A stinger assembly is provided which receives reeled tubing and is insertable to lock within the straddle assembly to create a flow path between the reeled tubing and exterior of the sleeve valve.
