METHOD FOR CONTROL OF PARAMETERS OF LIQUIDS POURED INTO A WELL Russian patent published in 2023 - IPC E21B21/08 E21B47/00 

FIELD: oil industry.

SUBSTANCE: invention can be used for repairing oil wells, maintaining reservoir pressure, treating the bottomhole formation zone with a reagent, killing a well, etc. In particular, a method is claimed for monitoring parameters of fluid injection into a well in a tank-pump-wellhead system, including the process of measuring, fixing, transmitting and processing parameters of fluid injection into a well, such as pressure, flow rate, density, temperature, in real time. At the same time, measurement of parameters of the injected fluid, such as the pressure at the injection line and the pressure at the wellhead, is carried out on the injection line by means of the first unit of equipment, and measurement of the parameters of the injected fluid, such as flow rate, density, temperature of the fluid, is carried out on the low pressure line located between the liquid container and the pump inlet, by means of a second piece of equipment. The fluid injection parameter data is transmitted from the first unit to the second unit via wireless or wired communication. In the second block, said data is processed and transmitted wirelessly or by wire to a personal computer.

EFFECT: increase of efficiency of controlling the process of pumping fluid into the well by providing real-time control of such parameters as pressure, temperature, flow rate and density.
