摘要： A stage cementer and inflation packer apparatus. The apparatus comprises a mandrel with an external closing sleeve and an operating sleeve interlocked therewith. Below the operating sleeve is an opening sleeve. The opening sleeve is mechanically acutated by a pump-down plug in a plug-operated embodiment or by a differential pressure acting on the opening sleeve in a hydraulically operated embodiment, to actuate the opening sleeve to allow inflation of the packer element. A back check valve prevents the packer from deflating. After the packer is inflated, additional pressure is applied which ruptures a rupture disc to open a port to the well annulus above the set packer element. Cementing may be carried out through this port, and after the cementing operating, a plug engages the operating sleeve to move the operating sleeve in the external closure sleeve, thereby closing the cementing port. After cementing is complete, the center components of the apparatus may be drilled out, leaving the external closure sleeve to permanently seal the cementing port.

摘要： Methods and apparatus are described which permit stage cementing within a well bore by means of a well tool which includes a cementer having cementing ports which may be responsively opened and closed by means of a knife gate valve. The knife gate valve is disposed within the housing between outer and inner cylindrical walls and being slidable therein between an open position, wherein the cementing port is open and fluid may be communicated therethrough, and a closed position, wherein the cementing port is closed thus blocking fluid communication through said port. The knife gate valve is further operationally associated with a driver assembly and trigger device adapted to receive a trigger signal and actuate the driver assembly in response thereto. In alternate exemplary embodiments, the trigger signal may comprise an acoustical, magnetic, electromagnetic wave, electrical or other suitable signal which is received by the trigger device. The driver assembly may comprise a hydraulic or pneumatic arrangement or a suitable electric motor arrangement.

摘要： An apparatus for opening perforations in a casing string. The casing string has a special casing section defining a plurality of holes therethrough. Rupturable ceramic discs or inserts are disposed in said holes and retained therein. The ceramic discs or inserts are adapted to withstand the fluid differential pressures normally present in the wellbore but are rupturable in response to impact by a mild explosive charge. The explosive charge is provided by detonating a length of det-cord disposed in the casing string adjacent to the holes in the special casing section. A method of perforating using this apparatus is also disclosed.

摘要： An apparatus for downhole injection and mixing of fluids into a cement slurry. The apparatus includes embodiments which either carry a fluid to the proper injection point in a wellbore or maintain it at the proper injection point until activated. In a first embodiment, the apparatus is characterized as a cementing plug having a fluid holding chamber therein. When the plug is pumped downwardly in the wellbore, the fluid in the chamber is flowed out of the chamber and mixed with the cement slurry by a venturi effect. In a second embodiment, the apparatus is characterized by a casing portion having a fluid holding chamber therein. A solenoid valve controls communication of the chamber with the well annulus, and fluid flow through the well annulus causes the fluid in the chamber to be flowed outwardly by a venturi effect. The second embodiment includes a casing shoe disposed below the fluid holding chamber. A third embodiment is disclosed which is substantially the same as the second embodiment except that it utilizes a casing cementing valve rather than a casing shoe. Methods of utilizing the apparatus to cement a well casing and mix a fluid, such as an accelerant, with the cement slurry are also disclosed.
