Description

Oil pumping and well workover integrated machine

Technical Field

The utility model relates to the field of oil extraction, in particular to an oil pumping and well repairing integrated machine.

Background

In the field of oil extraction, oil is pumped into an oil delivery pipe from the deep bottom and then is delivered into a transfer station, an oil pumping unit is firstly used, the oil pumping unit with the largest domestic use amount is of a walking beam reciprocating type, and the circular motion of a motor is changed into the vertical linear motion of an oil pumping rod through the oil pumping unit. The pumping unit has also certain range, and is tower type pumping unit with no walking beam and only tower, which converts the circular motion of the motor into the up and down linear motion of the pumping rod with steel cable and pulley. When a well pipe and an oil pump which are arranged under the ground need to be maintained, the pumping unit needs to be stopped, and the special workover rig is replaced to work.

The well repairing machine for repairing well pipe in oil producing well is driven with power machine to lift the oil pipe elevator connected with flexible steel cable and to lift the well pipe to ground for repair or replacement. It should be pointed out here that the flexible steel wire rope is more suitable for upward lifting, the lowering can only be carried out by means of the gravity of the tool assembly, a series of transmission resistance is overcome, the lifting tool is lowered and placed back to the position for lifting the well pipe for the next time, in order to quickly fall back, a series of balancing weights are generally configured, the energy consumption is additionally increased, in addition, the conveying capacity is lower, the lifting height is limited, in the long-time use process, the stable and reliable operation is difficult, the situation that the load falls due to the failure of a lifting part of the lifting machine is easy to happen, certain potential safety hazards exist, the maintenance frequency is high, moreover, the pumping unit and the workover rig are two sets of independent equipment, the universality is not universal, the investment is increased, the heavy workover rig is driven to perform well field operation, complicated post-repair work is also needed, for example, only temporary roads needed when the wellsite enters the field, the expense is not small, and other expenses are many.

It should be noted that the technology involved in the present invention, including dedicated devices such as spiral-grooved, spiral elevator, etc., has been partially disclosed and described in another patent application by the applicant. See application No. 202121091522.9 entitled "screw-driven well-pipe elevator used in oil recovery, application No. 202121097721.0 entitled" drive mechanism for screw elevator
