The invention provides a spray mixing device of a tracer agent. The device comprises an injection tube, a liquid inlet, a liquid outlet, a metal ball, a liquid storage barrel, a sealing cover and spray nozzles, wherein the liquid inlet is formed in the top part of the injection tube; the liquid outlet is formed in the bottom of the injection tube; the metal ball is arranged on the outer side of the middle part of the injection tube; the injection tube is fixedly connected with the metal ball; the 3 / 4 part of the metal ball penetrates through the sealing cover arranged at the top of the liquid storage barrel and extends into the liquid storage barrel; the 1 / 4 part of the metal ball penetrates through the sealing cover and is exposed on the outer side of the sealing cover; the metal ball is slidingly connected with the sealing cover; a plurality of spray nozzles are uniformly arranged at the bottom of the outer side of the liquid storage barrel; any of the spray nozzles faces downwards, and a 45-degree included angle is formed between the direction of each of the spray nozzles and the vertical direction. The device provided by the invention is simple in structure, low in cost and convenient to use, the tracer agent can be effectively and uniformly mixed with injected water, and an unnecessary error is reduced, so that a probing result is more accurate.
Description
[0001] (1) Technical field [0002] The invention relates to a tracer premixing device, in particular to a tracer spray mixing device. [0003] (2) Background technology [0004] With the development of my country's petroleum energy, water flooding has become one of the main methods to develop oil wells and enhance oil recovery. With the increase of water injection pressure and water injection volume, the geological conditions are becoming more and more complicated, and oil wells are often connected in series. If the judgment is inaccurate, it will cause greater difficulty in oil production. Therefore, oil wells need to be detected to ensure the safety of personnel and oil wells, and to improve oil recovery efficiency. In order to obtain information on the injection status of intervals and sublayers, radioactive isotope tracer methods are widely used in oilfields to measure injection profiles of injection wells. Usually, the situation is very complicated when the oil wells ar...
