Liquid pumping and discharging method and ground pumping system of exploratory well oil testing suspension type automatic pump

Abstract

The invention discloses a liquid pumping and discharging method and a ground pumping system of an exploratory well oil testing suspension type automatic pump. The liquid pumping and discharging method and the ground pumping system of the exploratory well oil testing suspension type automatic pump are used in an oil testing project of an oil exploration exploratory well to reduce damage of a travelling system of a tractor hoist, reduce energy consumption and improve safety. As a pumping reversing device is hung on an operating derrick, one end of a transmission belt on the pumping reversing device is connected with an optical rod in a mouth of a well while the other end of the transmission belt is connected with a balance block; a motor in the pumping reversing device provides power; and the motor rotates positively and negatively to drive an underground oil well pump to pump and discharge liquid so as to greatly reduce motor power and energy consumption and protect the travelling system of the tractor hoist. The pumping reversing device is arranged in a fixed frame which is hung on a hook or a big hook of the travelling system of the tractor hoist; the frame body of the fixed frame is fixed to the ground through a guy rope; and one end of a guide rail of a balance block is connected to the lower end of the fixed frame while the other end thereof is connected with a screw rod adjusting barrel. The liquid pumping and discharging method and the ground pumping system of the exploratory well oil testing suspension type automatic pump, disclosed by the invention, have the advantages of simplifying mounting construction, reducing energy consumption, protecting the travelling system of the tractor hoist, and lowering investment cost.

Description

technical field [0001] The present invention relates to a method and equipment for exploration well oil testing in the petroleum industry, in particular to a suspension type automatic pumping and drainage method for oil exploration well testing and a ground swabbing system, which can be used in the oil testing engineering of oil exploration exploration wells and reduce the number of drilling machines. Damage to the swimming system, reducing energy consumption ， Improve security. Background technique [0002] Drainage is the process link that can form the final conclusion for the entire oil testing process in the oil testing construction of exploratory wells in the petroleum industry, and it is also the process that takes the longest time in the oil testing process. In the past two years, the average single-layer drainage cycle for oil testing is 25.6-27.5 days, while the average single-layer oil testing cycle for some oilfields is about 50 days, accounting for more than hal...
