Problems solved by technology

The judgment and adjustment of the operating status of the oil production equipment by this system is not timely, and the working efficiency of the oil production equipment needs to be further improved
In addition, the existing oil production equipment can only adjust the static balance, that is, adjust the balance state before starting, but the balance cannot be adjusted during the operation of the oil production equipment

Abstract

The invention discloses a digital automatic oil extraction control system, which comprises a pressure sensor, a load sensor, a displacement sensor, a voltage sensor and a current sensor. The load sensor, the displacement sensor, a pressure sensor, the voltage sensor and the current sensor are all connected with an analog module of a programmable controller; the programmable controller is wirelessly connected with an upper computer; and the programmable controller controls an oil extractor motor through a transducer. The system also comprises an automatic counterweight imbalance adjusting mechanism arranged on a walking beam; the automatic counterweight imbalance adjusting mechanism comprises a movable counterweight block, a slide rail for supporting the movable counterweight block to move, and a motor playing a driving role for adjusting and balancing the counterweight block; and the programmable controller is connected with the motor for adjusting and balancing the counterweight block on an oil extractor. On the one hand, the system can conveniently finish oil extraction; and on the other hand, the system can judge the underground fault in time and change the counterweight condition so as to improve the oil extraction efficiency and achieve the energy-saving effect.

Description

technical field [0001] The invention relates to a petroleum digitized automatic collection and detection system, in particular to the control and method of working efficiency and automatic balance degree adjustment during the working process of a pumping unit. Background technique [0002] The automatic control of pumping rigs has been widely used in oil fields due to its convenience and energy-saving features. Part of its energy saving is to adjust the number of strokes or intermittent pumping after testing; the other part is to automatically adjust the number of strokes by measuring the input current. Relevant technologies have been found in "Petroleum Instruments" 1997.011(006).-15-17, "Microcomputer and Application" 1989.000(002).36-38 "Petroleum Industry Technical Supervision". 2002.018(008).-13-15 Involved, but all involve metering and digital automatic adjustment of the operating status of oil production equipment based on the indicator diagram and surface efficiency...
