Problems solved by technology
[0004] However, the existing nozzles all have certain nozzle damage (that is, the pressure loss caused by water passing through the nozzle), so in order to ensure that the water injection volume of each oil layer can meet the design requirements, it is often necessary to detect the nozzle damage
However, in related technologies, mouth damage detection methods usually use instruments to detect underground, and the detection efficiency is low

The present disclosure provides a nozzle loss pressure difference measuring device, which belongs to the technical field of measurement. The nozzle loss pressure difference measuring device includes a measuring body, a plug, a plug-type pressure gauge and a water outlet connecting pipe; the measuring body is provided with a first through hole, a first blind hole, a second blind hole and a connecting first through hole arranged along its axial direction. a through hole, a first blind hole and a communication hole of the first blind hole; the first end of the first through hole and the opening of the first blind hole are both connected to the water inlet of the measuring body, and the opening of the second blind hole is connected to the measuring body The second end of the plug is connected; the plug is installed in the first through hole, and a cavity for installing the water nozzle to be measured is set between the water inlet and the water outlet of the plug; the plugging pressure gauge is installed in the first blind hole, It is used to detect the pressure in the water inlet and the communication hole of the measuring body; the water outlet connection pipe is installed in the first blind hole. By using the nozzle loss pressure difference measuring device, the nozzle loss of the faucet can be measured on the ground, and the detection efficiency can be improved.
Description
technical field [0001] The present disclosure relates to the technical field of measurement, and in particular, to a device for measuring the differential pressure of nozzle loss. Background technique [0002] Layered water injection means that a packer is placed in the water injection well to separate the oil layers with large differences, and then the water nozzle in the water distributor is used to distribute water to each layer in layers, so that the water injection amount of the high-permeability layer can be controlled. A water injection method that enhances water injection in low-permeability oil layers and enables all types of oil layers to function. [0003] In the process of layered water injection, the water injection amount of each oil layer can be controlled by selecting nozzles with different diameters. For example, for a high permeability oil layer, the diameter of the nozzle can be selected to be smaller to reduce the water injection amount of the high perme...
