A mechanical hair selector for oil field perforation and coring with shock absorbing structure

Abstract

The invention relates to a mechanical hair selector for oil field perforation and coring with a shock absorbing structure, comprising a nylon resin layer and a coring orifice plate, one side of the nylon resin layer is hollowed out and connected with a drain hole, the nylon The inner side of the resin layer is provided with an outer straight rod, and one side of the outer straight rod is welded and connected with a connecting block, the inner side of the core-taking orifice is hollowed out and connected with a core-taking cylinder, and the core-taking orifice is located on one side of the connecting block, The inner side of the core barrel is provided with spray nozzles, and the hollow of the spray nozzles is connected with air holes, and the two ends of the core-taking orifice are provided with support blocks, and the outer sides of the support blocks are equipped with clad steel plates. The beneficial effects of the present invention are: the textile cleaning device with multi-directional positioning and stirring function is provided with a shift lever, through the installed shift lever and the gear slot on one side of the shift lever, due to the triangular structure, It is carried out in the way of switching gears, the operation is simple and flexible, and there will be no accidents of stalled and disordered gears, which improves the operational stability of the equipment.

Description

technical field [0001] The invention relates to the technical field of hair selectors, in particular to a mechanical hair selector for oil field perforation and coring with a shock absorbing structure. Background technique [0002] Coring refers to the process of sampling the rocks of the drilled strata in order to understand the geological conditions of the stratum. The coring is completed through the coring barrel. The traditional coring barrel is connected to the bottom end of the drill pipe close to the drill bit, and the coring cutting head cuts into the stratum. Finally, the coring barrel can be used to take the core continuously, and then take it out from the drill pipe. The perforating gun is a combination of equipment and accessories used for perforating oil and gas wells. At present, the energy-shaping perforating gun is widely used. The energy-gathering phenomenon of the fried flower produces the energy-gathering jet, which shoots away the stratum. [0003] In th...
