Problems solved by technology
The operator manually adjusts the amount of injection according to the water injection process. Since the gate valve or stop valve is not suitable for regular adjustment, the screw and nut are worn and easy to leak, and due to the time lag effect of manual control, the abnormal situation of water injection cannot be handled in time. Especially at night, due to pressure fluctuations, the operator cannot detect and deal with it in time, causing the water injection volume to be out of control or anti-vomiting "backward flow", and in severe cases, sand will be produced in the formation, seriously affecting the stable development and safe production of the oil field

The invention relates to water injection well control detection equipment, in particular to an intelligent flow monitoring device of a water injection well. A data collecting module comprises a single-chip microcomputer, a flow meter and a valve control module. A GPS communication module, the flow meter and the valve control module are connected with the single-chip microcomputer respectively, and the GPS communication module and a monitoring center perform remote wireless communication. According to the structure, the flow meter is used for monitoring the flow of the oil field water injection well and transmitting real-time detection values to the single-chip microcomputer, the single-chip microcomputer controls opening of a valve through the valve control module according to parameters set in advance, remote monitoring of the oil field water injection well is realized by the utilization of connection between the monitoring center and the GPS communication module and through a GPS wireless communication network and a computer network technology, and collected data are transmitted to the monitoring center through the GPS communication module. Thus, a worker can obtain site working condition information timely and accurately without going to the site, the working state of the equipment can be judged at any time, faults can be found out timely, and losses caused by accidents are lowered.
Description
technical field [0001] The invention relates to a control and detection device for a water injection well, in particular to an intelligent flow monitoring device for a water injection well. Background technique [0002] In the later stage of oil resource exploitation, due to the drop of formation pressure, water injection is often used to supplement the oil field energy. The purpose of oilfield water injection is to maintain the energy of the oilfield, maintain the pressure of the oil layer, increase the liquid supply capacity, reduce the decline rate of crude oil, and achieve the purpose of further oil extraction. It is an important means to achieve high and stable crude oil production. Especially when the oil field enters the middle and late stage of development, the effect of various oil increase measures is getting worse and worse, and it is becoming more and more difficult to stabilize production. Strengthening effective water injection is the key to improving the oil f...
