Embodiment Construction

[0024] The operation steps of oil well operation and completion are as follows:

[0025] 1. After the completion of the oil well operation, the beam of the pumping unit is in the horizontal position; lift the oil rod on the operation vehicle, raise the anti-shock distance of the oil pump to a suitable position, and then tighten the brake on the operation vehicle. The upper end of the packing box is fixedly connected to the unloading square clamp at the 25-35cm of the oil pumping rod; and the oil pumping rod is lowered with a working vehicle, and under the action of the weight and inertia of the oil pumping rod, it is checked that the unloading clip has been firmly connected to the oil pumping rod.

[0026] 2. Use the work vehicle to lift the polished oil rod, and place a long seat tube outside the polished oil rod between the unloading clamp and the wellhead packing box, and one side of the long seat tube is fixedly connected to the ladder; The elongated seat tube can be as di...

Abstract

The invention discloses a beam-pumping unit operation well completion hung sucking method, relates to the technical field of oil field operation, and in particular to a well completion hung sucking technique after under-well operation. According to the beam-pumping unit operation well completion hung sucking method, hung sucking is implemented in a base barrel manner, an unloading square clamp is equivalent to a polish rod anti-dropping clamp, the unloading square clamp does not need to move any longer, and a smooth sucker rod which is fed into a wellhead packing box is free of tooth mark of burr after hung sucking is completed. By adopting the beam-pumping unit operation well completion hung sucking method, operation well completion hung sucking is rapidly and simply achieved, and enterprises gain both benefits and time for production.

Description

technical field [0001] The invention relates to the technical field of oilfield operations, in particular to the well completion hanging pumping technology after downhole operation. Background technique [0002] At present, beam pumping units adopt energy-saving permanent magnet motors. The advantages of this motor are energy saving, but the disadvantages are no differential speed operation and low starting power. The permanent magnet motor is equipped with 15KW, 22KW, 30KW and other specifications according to the model of the pumping unit and the downhole load of the oil well. The permanent magnet motor hangs the load on the donkey head of the pumping unit, which can meet the needs of oil well pumping under production conditions and play a role in saving electric energy. When the oil well is working underground, the donkey head of the pumping unit is in a no-load state. If the permanent magnet motor is started at this time, the motor will not be able to drive the pumping ...
