Pumpingunit long-distance information transmission and control device and control method

Abstract

The invention includes three main parts: information acquisition and control terminal 1 for pumping unit installed on pumping unit on site; telemonitoring device 2 for receiving operating data from and sending control commands to remote pumping unit; being broken away from monitoring center, online monitoring devices 3 based on fixed telephone, 'Xiaolingtong'and handset. Through public telephone network in DTMF signal form and telemonitoring device 2, information acquisition and control terminal 1 is connected to online assistant monitoring devices 3 including fixed telephone, 'Xiaolingtong'and handset. Possessing functions of transferring running information of remote pumping unit, remote control, reporting fault of pumping unit, and implementing unmanned inspection and operation, the invention increases yield of oil well, and reduces accident rate.

Description

(1) Technical field [0001] The invention relates to the field of remote information transmission and control, in particular to the field of remote information transmission and control for oil field pumping units. (2) Background technology [0002] Various failures often occur in the pumping unit. When the underground liquid supply capacity of the oil well is less than the discharge volume, it will cause liquid hammer and pumping out. The high stress generated by the liquid impact on the sucker rod will cause the sucker rod to fall off and break, causing the oil well to stop production; when pumping is empty, although the pumping unit is working, there is no liquid output, and the pumping unit consumes energy in idling; in addition, when the pumping unit When the transmission belt or the key pin in the transmission chain fell off, the motor was still rotating, and the pumping unit had no liquid output, and also produced empty consumption, and so on. Since the operation of th...

Problems solved by technology

It is not very convenient to conduct continuous manual inspections or to send special personnel to monitor. Even if a special person can be sent to inspect, there are disadvantages: 1. Failure to check the faulty pumping unit in time; 2. The labor cost is too high; 3. The accuracy is not high

The patent application No. 200510066430.4 proposes a remote wireless monitoring system based on GPRS network, which can realize the operation monitoring of oil fields. There is no network coverage in some places, or the signal is unstable

In addition, if a professional base station is established, the cost is too high

In addition, it is not enough to only carry out remote information transmission on the pumping unit in the field, such as the technical solution recorded in the patent document of Patent No. 97100222, this technical solution can only realize remote information transmission, but cannot realize remote control
