The swellable element is at least partially disposed between and fixed to the first and second retainers. The piston is fixed to the second retainer and configured to move the second retainer from a first position in which the swellable element is unstrained, to a second position in which the swellable element is strained. The piston lock is configured to releasably fix the second retainer in the second position.

摘要： An apparatus and method provides an anchoring apparatus for use in a wellbore that comprises a gripping assembly and an actuation assembly. In one arrangement, the actuation assembly includes a motor and a module having at least a compressible element (e.g., a hydraulic module) between the motor and the gripping assembly. Upon activation, the motor actuates the hydraulic module to cause activation of the gripping assembly. In one arrangement, the anchoring apparatus is designed to pass through a tubing or other restriction in the wellbore. When in the retracted state, the gripping assembly of the anchoring apparatus has an outer diameter that is smaller than an inner diameter of the tubing. When in the expanded state, the gripping assembly of the anchoring apparatus has an outer diameter than is substantially the same as the inner diameter of the liner to enable engagement of the gripping assembly against the liner.

摘要： A perforating gun includes a guide, a first charge unit, a second charge unit and a linkage. The first and second charge units are coupled to the guide. The second charge unit is capable of being in a collapsed position for passing the second charge unit through a tubing and is capable of being in an expanded position for detonating the second charge unit. The linkage is connected to the second charge unit to communicate an applied force to cause the second charge unit to move the second charge unit along the guide toward the first charge unit when the second charge unit is at least partially in the expanded position.

摘要： A LED (Light Emitting Diode) bulb structure includes a base, a plurality of fins and a shell. One end of the base is electrically connected to a power source, and the other end of the base is used for holding a LED light source. The fins are disposed on a surface of the base. The shell encloses the fins, and the shell includes a plurality of first heat-dissipation holes and a plurality of second heat-dissipation holes. The first heat-dissipation holes are arranged around the shell and corresponding to the fins for allowing airflow entering the first heat-dissipation holes to directly pass through each of the fins corresponding to each of the first heat-dissipation holes. The second heat-dissipation holes are arranged around the shell and disposed above the first heat-dissipation holes for enabling the first heat-dissipation holes and the second heat-dissipation holes to conduct thermal convection.
