Problems solved by technology

The traditional coring device and the core pushing device are installed and fixed together. When using it, it is necessary to install a hydraulic lifting device at the same height as the coring device, otherwise it will interfere with the ground. This setting method not only increases the manufacturing cost, but also applies Poor performance, unable to meet the core pushing needs of core removers with different diameters

Abstract

The invention discloses a core-pushing mechanism for a coring device used in oil exploitation, which comprises a support seat, a rotating screw is connected in the middle of both ends of the support seat, the lower end of the rotating screw is connected with a limit pad, the bottom end of the limit pad is connected with a fixed seat, and the upper end of the support seat is Both sides are connected with a hydraulic cylinder, the upper end of the hydraulic cylinder is connected with a hydraulic shaft, the upper end of the hydraulic shaft is connected with a push core box, the middle part of the inner side of the push core box is provided with a limit sleeve, the middle part of the limit sleeve is connected with a screw rod, and the left end of the middle part of the screw rod is connected with a second A slider, the middle part of the front end of the first slider is connected with the first fixing rod, the middle part of the right end of the first fixing rod is connected with the first clamping block, the right end of the middle part of the screw rod is connected with the second slider, and the middle part of the front end of the second slider is connected with The second fixing rod is connected with a second clamping block in the middle of the left end of the second fixing rod. The present invention realizes the clamping and fixing of the coring devices with different diameters through the design, and also realizes the deeper core pushing function of the coring device under the condition of the hydraulic shaft of the same height.

Description

technical field [0001] The invention relates to the technical field of oil exploitation equipment, in particular to a core-pushing mechanism of a corer for oil exploitation. Background technique [0002] Oil extraction refers to the act of digging and extracting oil in places where oil is stored. In the process of oil extraction, oil and gas flow from the reservoir to the bottom of the well, and then rise from the bottom of the well to the wellhead. There are still many areas in the world that have not yet been explored or fully explored. Oil and gas exploration in deep strata and deep ocean waters has just begun, and more oil and gas reservoirs will be discovered. The application of enhanced oil recovery technology in developed oil and gas reservoirs can The amount of crude oil extracted is also quite large; these all indicate that the science and technology of oil and gas extraction will have greater development. [0003] Well logging is an effective way to obtain variou...
