Problems solved by technology

[0004] 1) The operation efficiency is low. In the specific operation process, it takes a lot of time to make an appointment for the crane and transport the crane to the side of the pumping well for operation, which greatly affects the normal operation of the pumping well
[0005] 2) The lifting cost of using a crane to lift the sucker rod is relatively high;
[0006] 3) Generally, multiple people are required to carry out the lifting operation, which wastes manpower

Abstract

The invention discloses a sucker rod lifting device which comprises two stand columns. The two stand columns are fixedly arranged on the two sides of a rod-pumped well and are vertically provided with transmission rods which can vertically move along the stand columns respectively. The tops of the two transmission rods are connected with a lifting beam. The two transmission rods are connected with a drive device through a transmission assembly. An upper clamping piece is arranged in the middle of the lifting beam. A lower clamping piece is arranged between the two stand columns and below the upper clamping piece. The sucker rod lifting device is simple in structure, and lifting is convenient and rapid; two links of steam injection and oil production can be continuously switched, labor is saved, and meanwhile lifting cost of a sucker rod is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of petroleum exploitation, and in particular relates to a sucker rod lifting device capable of realizing integration of petroleum injection and production. Background technique [0002] The sucker rod is a slender rod of the pumping well, it is connected to the polished rod on the top, and the pump is connected to the bottom to transmit power. The length of a single sucker rod is 7.6 or 8 meters. The material is generally high-carbon steel plated with hard chromium. The oil pipe is connected one by one with an internal thread hoop and extends to the rotor at the underground oil layer, and the oil is pumped by rotation. . [0003] As we all know, in the process of oil exploitation, steam injection operation is carried out regularly, and the steam injection operation needs to lift the sucker rod out of the pumping well, and the current method is to use a crane to lift the sucker rod out of the pumping well A...
