Safety protection device for wellhead of pumping unit

Abstract

The invention discloses a safety protection device for a wellhead of a pumping unit. The safety protection device for the wellhead of the pumping unit comprises a base. A plurality of sets of mountingholes are formed in the edge of the base. Fixing columns are arranged in the mounting holes. Circular mounting openings are formed in the upper end face of the base. Annular protective plates are vertically and fixedly arranged between the circular mounting openings and the edge of the base. The two sides of the annular protective plates are connected with a horizontal U-shaped insertion rod in asleeved mode by through holes. The end, near the center of the base, of the horizontal U-shaped insertion rod, located at the inner side of the annular protective plates is fixedly provided with an arc-shaped plate. Springs are arranged on the outer portions of the upper and lower ends of the horizontal U-shaped insertion rod between the inner side of the annular protective plates and the middleof the outer side of the arc-shaped plate in a sleeved mode. Screws are installed at the middle of the horizontal U-shaped insertion rod and the middle of the outer side of the arc-shaped plate through bearings. According to the safety protection device for the wellhead of the pumping unit, the annular protective plates and protective cover are arranged to completely protect the wellhead, the structure is stable, the accident of falling into a well caused by the overturn of the protective cover is prevented, the safety is high, and the adjustable arc-shaped plate enlarges the application scopeof the device.

Description

technical field [0001] The invention relates to the technical field of oil well exploitation, in particular to a wellhead safety protection device for a pumping unit. Background technique [0002] The oil well is the hole drilled according to the well layout system of the oil field development plan for the exploitation of oil. The oil rises from the bottom of the well to the wellhead. , and inject oil well cement into the annular space between the casing and the well wall to maintain the well wall and seal the oil, gas, and water layers, and then use the perforating gun to open the oil layer according to the requirements of oilfield development to form a channel and lower the tubing. Oil is raised from the bottom of the oil well to the head of the well with a suitable induction method. [0003] In the prior art, the wellhead after the operation of the pumping unit is exposed to the environment, and there are the following problems: [0004] 1. The protection measures set a...

AI Technical Summary

Problems solved by technology

[0004] 1. The protection measures set at the wellhead are not safe, accidents are prone to occur and the wellhead itself is not protected

[0005] 2. The protection measures taken for the wellhead are not only difficult to install and disassemble, but also have a narrow range of use, which cannot be used universally for wellheads of pumping units of different sizes
