Oil well long-distance wireless monitoring system

Abstract

The invention discloses an oil well long-distance wireless monitoring system which comprises a programmable logic controller (PLC), wherein the PLC is connected with an oil well oil temperature detector, a big station water temperature detector, a converging pipe oil temperature detector, a converging pipe oil pressure detector and a metering room inflammable gas detector, and the PLC is provided with a signal transformation sending device, a signal transformation device and a comparator which is connected with a warning device. The oil well long-distance wireless monitoring system further comprises a well area centralized monitoring host used for receiving oil well related data information sent by the signal transformation sending device of the PLC through a wireless bridge, wherein the well area centralized monitoring host is provided with a decoder and a comparator which is connected with the warning device. By means of the operation of computer programs of the PLC and the well area centralized monitoring host, whether numerical indicators of an oil well are out of scope or not can be judged, and then whether the warning device is started or not can be determined. Therefore, labor intensity can be greatly reduced, and the operation states of the oil well in a well area can be well monitored.

Description

technical field [0001] The invention relates to an oil well remote wireless monitoring system capable of monitoring in real time the oil outlet temperature of the oil well, the temperature of incoming water at a large station, the oil temperature, pressure and combustible gas content of a header pipe in a metering room. Background technique [0002] Most of the well-known oil well equipment inspections currently use manual well inspection. A mine is divided into several well teams, and each well team is responsible for a certain number of oil wells. Manual well inspection usually leads to an oil well that may not be inspected for several days. It has been realized that if the oil outlet temperature of the oil well is too low, it may cause wax formation in the oil well, which will affect the normal production of the oil well. In order to prevent the oil well from wax formation, it is necessary to clean the well regularly. Prevent oil wells from waxing Regular well washing wil...

[0002] Most of the well-known oil well equipment inspections currently use manual well inspection. A mine is divided into several well teams, and each well team is responsible for a certain number of oil wells. Manual well inspection usually leads to an oil well that may not be inspected for several days. It has been realized that if the oil outlet temperature of the oil well is too low, it may cause wax formation in the oil well, which will affect the normal production of the oil well. In order to prevent the oil well from wax formation, it is necessary to clean the well regularly. Prevent oil wells from waxing. Regular well washing will greatly increase the number of well washings, resulting in unnecessary waste. In addition, increasing the number of well washings will also reduce the efficiency of crude oil recovery.
