摘要： In a retrievable packer adapted for service under high temperature and high pressure operating conditions, the packer is purpose-designed as a cut-to-release packer. That is, this retrievable packer has no built-in release mechanism. An internal cinch slip is used to retain the packer in its set position and thereby prevent the accidental release of the packer. The only way it can be released is by severing the mandrel. The cut point is opportunely designed so that the mandrel is severed in a precise location such that not only is the packer released, but all the packer and tail pipe are then retrievable as a unit. The primary advantage of a cut-to-release packer is that it can withstand extreme tubing loads occurring during production and stimulation.

摘要： In a retrievable packer adapted for service under high temperature and high pressure operating conditions, improved retention of the packer in the wellbore is achieved by use of an inventive slip and wedge system, wherein the cones on the wedges are spaced a progressively slightly greater distance apart from their corresponding slip cones, from the centermost slip cone to the outermost slip cone. This forces the center of the slip to be loaded first. As greater forces are exerted on the wedges from end to end, the wedge will deform slightly and the next cone of the wedge will make contact with its matching portion of slip. Thereby, as the wedges are loaded higher and higher, more wedge cones come into bearing contact with the slip. Further, a barrel slip is used, to provide a uniform circumferential distribution of forces. This design effectively allows initial setting of the packer with very little slip tooth contact area. This permits the slip to quickly get a good grip into the casing wall. Subsequent higher loading brings more and more slip teeth to bear and prevents overstressing the casing.

摘要： The present inventions contemplate an improved well tool actuator and method that does not require more expensive downhole equipment and can be utilized with limited actuation pressures. According to the improved well tool actuator and method of the present inventions, a fluid pressure intensifier is placed in the well and coupled to the downhole device to be manipulated. By using a fluid pressure intensifier the actuation pressure can be increased to a pressure sufficient to operate or manipulate the downhole device without the necessity of increasing the tubing pressure. According to the present invention the actuation pressures supplied by the intensifier can exceed the safe operating rated pressures of the well tubing and equipment. The well tool actuators of the present invention are self-contained in that they are powered from the tubing fluid pressure itself without a high-pressure hydraulic or electrical connection to the surface. According to the present inventions, subterranean hydraulically actuated well tools can be actuated at higher pressures than the supplied pressure. Fluid pressure intensifiers circuits can be assembled in and carried downhole with the actuation tool and removed once the actuation process is complete. Also, fluid pressure intensifier circuits can be assembled as a part of the well tool and operated remotely.

摘要： A detector structure is used to sense and log the joints in a downhole jointed tubular structure, such as a well bore casing or production tubing, in a subterranean well. The detector is moved through the jointed tubular structure on an elongated positioning member, representatively a slick line, through a series of joints to be logged. As the detector passes through each joint it electromagnetically senses the joint and responsively generates an electric output signal. The output signal is used to momentarily cause a drag structure portion of the detector, in cooperation with the interior side surface of the tubular structure, to momentarily create a detectable tension change in the elongated positioning member. Alternatively, a pyrotechnic or compressed gas device may be used to create the detectable changes in response to the generation of the electrical output signals. These tension changes, which may be either tension increases or tension decreases, serve as mechanical output signals transmitted upwardly through the positioning member, and may be plotted on a strip chart recorder at the surface to record the joint locations and correlate them to the lowered depth odometer readings of the detection system. Using this joint detection apparatus, correlative joint logging procedures may be carried out for tool setting purposes without the necessity of utilizing an electrical conductor line.

摘要： Apparatus and methods are provided for anchoring within tubular structures and releasing therefrom. In a described embodiment, a packer includes multiple debris barriers, which are deployed when slips of the packer are radially outwardly extended. The debris barriers prevent debris from settling about the slips, thereby enhancing convenient retrieval of the packer. Use of the debris barriers may also permit control over how the slips are extended.

An alternate form of the mandrel includes a pipe plug hole and a pipe plug in the adapter for access to the flow passage in the adapter to drill the port into the tubing when the mandrel is mounted on the tubing during the mounting procedure. The mandrel is readily secured on the tubing at desired locations as the tubing is run into a well.
