Description

technical field [0001] The invention relates to an elevator used for oil field wellhead operations, belonging to the technical field of petroleum equipment. Background technique [0002] In drilling engineering, an elevator is a tool used to lift pipes such as drill pipes, tubing and casing. It is suspended in the lifting rings on both sides of the hook of the hoisting system, so that the drilling tools, tubing and casing can be pulled out or run in the wellbore. Elevators have different specifications corresponding to the drill string to be hoisted. Elevators are mainly divided into the following categories: casing elevators; tubing elevators; drill pipe elevators; sucker rod elevators. [0003] Casing elevator is an essential tool for lifting and running casing in oil and gas drilling operations. [0004] The tubing elevator is a special tool for lifting or lowering the pipe string in oil drilling and production. [0005] Drill pipe elevator is an important tool for li...
