The invention provides a jet flow mixing device which comprises a mixing unit, a liquid inlet pipe, a nozzle and a flow distributing pipe, wherein a mixing cavity is formed in the mixing unit; a feeding hole for feeding solid raw materials into the mixing cavity is formed in the top of the mixing unit; a liquid inlet for inputting liquid raw materials into the mixing cavity and an outlet for discharging a mixture from the mixing cavity are formed in side walls of the mixing unit; the liquid inlet and the outlet are opposite to each other; a runner for liquid flowing is formed in the liquid inlet pipe; the nozzle comprises an input opening communicated with the runner of the liquid inlet pipe, a nozzle orifice communicated with the liquid inlet of the mixing unit, and a vent communicated with the input opening and the nozzle orifice; the cross sectional area of the nozzle orifice is smaller than the cross sectional area of the runner; the flow distributing pipe is communicated with the runner of the liquid inlet pipe; and a first switching valve is arranged on the flow distributing pipe. According to the jet flow mixing device provided by the invention, the service life of the nozzle can be prolonged.
Description
technical field [0001] The present application relates to the field of oil collection, in particular to a jet mixing device. Background technique [0002] In the middle and late stages of oilfield development, supplementing formation energy by water injection is the main measure adopted by most oilfields in my country. In order to improve the water injection effect and the ultimate recovery factor of the oil field, the polymer flooding technology is generally adopted in the production site of the oil field. The polymer flooding technology is to configure a high-viscosity polymer solution, and then mix the configured polymer solution with the injection water to increase the viscosity of the injection water, increase the sweep coefficient of the injection water, and then improve the water injection effect and the oil field. ultimate recovery rate. [0003] At present, the polymer solution required for configuring the polymer flooding technology usually uses high-speed water ...
