During the National Day, a new type of protection device for pumping units "failure" was successfully tested in the Gao 6-11 wells of Jiangsu Oilfield
This kind of protection device uses the angle sensor installed on the beam to perceive the pumping unit that is normally running in a horizontal state.
At 3 o'clock in the morning on October 8, 2020, the crank pin of the pumping unit Gao 6 Ping 8 in the Gaoji Oilfield of the Second Oil Production Plant came out of the crank shaft hole, causing the pumping unit to skew
Based on the statistical data on the maintenance of pumping units in more than 100 oil wells in Block 6, he found that the crank pin bearings of many pumping units have different degrees of wear.
At present, beam pumping units widely used in oil fields are mostly scattered on oil wells in the field.
It is understood that the beam pumping unit used in the oil field has a life of about 15 years.
"According to the current patrol inspection procedures for beam pumping units, there is no rigid requirement to stop the machine to check the bearings at all parts
