Float casing collar is a special component in cementing operation, its function is to prevent backflow of bottom hole slurry during casing running process, so that the casing can be run smoothly. Float casing collar makes cementing operations safer and more reliable. Due to the special functions of the floating hoop and the floating shoe, it is necessary to test the compressive strength and sealing performance of the product before leaving the factory to ensure the quality and reliability of the floating hoop and the floating shoe.
In order to meet the forward and reverse pressure test requirements of different sizes of floating hoop and floating shoes, and to overcome the problems of poor sealing and large structural stress caused by the pressure test under high pressure, the structure of the pressure test device was designed and studied. The floating shoe pressure test device mainly includes a mechanical main body, a hydraulic drive device, a water pressure device, and a control device, and the mechanical main body is composed of a bearing frame, a screw drive, a gear drive, a T-slot inclined surface clamping mechanism, and a radial embracing mechanism. It is composed of a transmission mechanism composed of a type sealing mechanism, a scissor type lifting and a slope type conveying mechanism, etc. In order to meet the pressure test workflow, all parts of the pressure test device work in coordination to automatically complete the pressure test task of the floating hoop and floating shoe. The overall layout of the pressure test equipment adopts a suspended structure in the abdomen of the rack, and a symmetrical closed-frame self-supporting structure is designed, which improves the reliability of the pressure test equipment.
