Abstract

The invention discloses a wellhead device, which includes a device casing and a wellhead device body. The wellhead device body is located inside the device casing. A disc is fixedly connected to the outside of the wellhead device body, and arc-shaped clamping blocks are symmetrically arranged on the outside of the disc. , the bottom ends of the arc-shaped clamping blocks are fixedly connected with a support plate, the bottom ends of the support plate are slidably connected with a first slide rail, and both sides of the support plate are slidably connected with a second slide rail; by setting the first The motor and the second motor make the first motor and the second motor drive the first lead screw and the second lead screw to rotate respectively, and then the support plate drives the arc-shaped clamping block to clamp the disc. By setting the third motor, the The third motor drives the third lead screw to rotate, and then the U-shaped bottom plate drives the wellhead device body to move up and down, which plays a role in lifting the wellhead device body and reduces the working intensity. The device body is easy to move.

Description

technical field [0001] The invention relates to the technical field of oil exploitation, in particular to a wellhead device. Background technique [0002] In oil and natural gas drilling, it is installed at the wellhead to control the pressure and direction of gas and liquid (oil, water, etc.), suspend casing, oil pipe, and seal the oil pipe and casing and the annular space of each layer of casing; generally by It consists of casing head, tubing head, blowout preventer group, cross, and bypass pipe fittings; Christmas tree and gas tree are also wellhead devices; petroleum is a fluid mineral buried deep underground; initially people regarded the oily liquid mineral produced in nature as It is called petroleum, the combustible gas is called natural gas, and the solid combustible fuel mineral is called asphalt; with the deepening of the research on these minerals, it is realized that they are all hydrocarbon compounds in composition and are related to each other in origin, so t...
