Energy-saving automatic oil extraction control system of pumping unit

Abstract

An energy-saving automatic oil extraction control system of a pumping unit comprises a GPRS (general packet radio service) network, an acquisition terminal, an oil measuring terminal parameter acquiring module, a heating furnace terminal parameter acquiring module, a wireless video module, a wireless remote module, a wireless displacement and load integrated sensor, a wireless dynamic liquid level sensor, a wireless temperature sensor, a wireless pressure sensor, a radio parameter acquiring module, a wireless data acquiring terminal, a pumping unit dynamic balance detector, a user network terminal machine, an internet access device, a terminal machine and a server. The wireless displacement and load integrated sensor, a wireless pressure module and the radio parameter acquiring module are respectively communicated with acquiring terminals via wireless signals; and the server is communicated with the GPRS network via wireless signals. The energy-saving automatic oil extraction control system has the advantages that the energy-saving automatic oil extraction control system is favorable for saving large quantities of electric resources and human resources, can find out work statuses of an oil well in time, and reduces environmental pollution and gas emission. In addition, the energy-saving automatic oil extraction control system brings huge economic benefits for the country and enterprises.

Description

technical field [0001] The invention relates to the field of oilfield signal acquisition and processing equipment, and in particular provides an automatic control system for energy-saving oil recovery of a pumping unit. Background technique [0002] With the advent of secondary and tertiary oil recovery periods in oilfields, the phenomenon of pumping out of pumping wells is becoming more and more serious. This not only seriously wastes electric energy, but also greatly increases the cost per ton of oil. In order to effectively solve this problem, many companies at home and abroad are actively exploring and put forward some better solutions. For example, ultrasonic and infrasonic waves are used to monitor the dynamic liquid level of oil wells, etc. However, these schemes have a common feature, that is, the detection accuracy of the liquid level is low, and the error per kilometer is mostly about 8%, making it difficult to achieve precise oil recovery and remote precise cont...
