Do you know the function of the monitoring device of the intelligent water distributor integrated with the vortex flowmeter?

In this article, the editor wants to talk to you about the application of the detection device of the intelligent water distributor integrated with the vortex flowmeter, and what role does it have at the same time? With the deepening of oilfield development, the number of separate injection layers in water injection wells has increased year by year, and the difficulty of layered testing has also increased year by year, and the testing workload has increased significantly. Improving the water injection well layered testing technology can effectively improve the water injection development effect, and provide a basis for further selection of reasonable oil production process measures and multi-layer injection plans. Commonly used downhole flowmeters include electromagnetic flowmeters, ultrasonic flowmeters and turbine flowmeters. These flowmeters have some difficult problems to solve in the process of use: electromagnetic flowmeters, the measurement accuracy is affected by the conductivity of the measured medium, and the induced electrical It is very easy to be covered by oil pollution, which affects the test effect; ultrasonic flowmeter can only be used to measure clean liquids and gases, and the oil-water mixture in the downhole medium is not uniform, which affects the test effect; the measurement accuracy of turbine flowmeter is affected by the viscosity of oil pollution, and the turbine is easily damaged. Dirt and rust are stuck, resulting in inaccurate measurement and affecting the test effect. The accuracy of the downhole flowmeter on the water injection volume test directly affects the quality of the water injection effect, so it is necessary to develop a high-precision downhole flow measurement and adjustment system. The purpose of this is to overcome the various deficiencies of conventional downhole flowmeters in the process of layered testing of water injection wells, to realize direct and real-time detection of water injection well flow, to accurately reflect the state of downhole liquid flow, and to be durable and suitable for various complex downhole conditions. .

Beneficial effects of the present invention: The flow monitoring device of the intelligent water distributor integrated with the vortex flowmeter of the present invention is a flowmeter designed and manufactured according to the principle of Karman vortex street and modern electronic technology. The fluid vortex generated by the liquid flowing through the vortex generating body produces alternating pressure on the vortex generating body of the triangular column. The electrical signal detected by the piezoelectric signal sensor is amplified by the preamplifier and becomes a standard electrical signal output. Thereby, the flow rate of the measured medium can be obtained. The invention can intuitively monitor the flow data of the downhole liquid from time to time, and overcomes the difficulty that the storage type downhole flowmeter cannot timely monitor the flow rate of the downhole liquid. u200bu200bu200bu200bNow, have you all understood the role of the detection device of the intelligent water distributor integrated with the flowmeter?
