In-service beam pumping unit horsehead shaking detection device

Abstract

The invention discloses an in-service beam pumping unit horsehead shaking detection device, and belongs to the pumping unit detection equipment technology field. The in-service beam pumping unit horsehead shaking detection device comprises a signal transmitter, a transmitter fixing device, a signal receiver, a receiver fixing device, and a computer. The signal transmitter comprises a laser and a power supply. The transmitter fixing device is disposed on an oil field well mouth device, and the laser and the power supply are disposed on the transmitter fixing device. The signal receiver comprises a CCD sensor, and the receiver fixing device comprises an A magnetic base and a connecting board. The CCD sensor is disposed on the lower surface of the connecting board, and the connecting board is disposed on the upper surface of the A magnetic base. The A magnetic base is fixedly disposed on an upper surface of a rope hanging device, and the laser is disposed right under the CCD sensor. The detection of the in-service beam pumping unit horsehead shaking range without requiring shut-down of on-site devices is realized, and a scientific determining basis is provided for the safe operation and the maintenance of the pumping unit.

Description

technical field [0001] The invention relates to the technical field of detection equipment for oil pumping units, in particular to a donkey head shaking detection device for in-service beam pumping units. Background technique [0002] With the increase of the operating life of the beam pumping unit, there are phenomena such as loosening of the foundation soil, wear of the beam fulcrum bearing, and cracking and deformation of the donkey head, which will affect the alignment between the donkey head suspension point of the pumping unit and the axis of the wellhead device. The seals of the pumping well and the packing of the Christmas tree caused wear, which affected oil production. At present, the CCD measuring devices used in the detection method of the donkey head shaking of the pumping unit all need to stop the pumping unit on site and install the detection equipment, which causes losses to the on-site production and operation, and also causes inconvenience to the production...

Problems solved by technology

[0002] With the increase of the operating life of the beam pumping unit, there are phenomena such as loosening of the foundation soil, wear of the beam fulcrum bearing, and cracking and deformation of the donkey head, which will affect the alignment between the donkey head suspension point of the pumping unit and the axis of the wellhead device. Pumping well seals and Christmas tree packing causing wear, impacting oil production

At present, the CCD measuring device used in the detection method of the donkey head shaking of the pumping unit requires the on-site pumping unit to be shut down to install the detection equipment, which causes losses to the on-site production and operation, and also causes inconvenience to the production management.
