METHOD FOR IMPROVING THE RELIABILITY OF THE RESULTS OF CYCLIC DETERMINATION OF THE WATER CONTENT OF PRODUCED OIL Russian patent published in 2023 - IPC E21B47/10 

FIELD: oil and gas industry.
SUBSTANCE: invention and can be used to obtain reliable information about the characteristics of an oil-containing stream produced from an oil well. The method for increasing the reliability of the results of the process of cyclic determination of the water cut of produced oil includes three phases: filling, measuring and blowing the device that determines the water content, performed sequentially, while before the blowing phase of the specified device, an additional setting is carried out, which consists in calibrating the data necessary for calculation of the water content value of the oil-containing liquid. At the same time, the procedure for conducting this mode includes three sampling from the measuring chamber filled with liquid from the separator, entering the measuring chamber from the separator from different heights and containing the product with different degrees of water content, the value of which is calculated in a laboratory and then entered into the memory of the computing box to ensure the accuracy of the further indications.

EFFECT: technical result consists in increasing the reliability of the information received regarding such characteristics of the produced oil-containing stream as its water content, density and gas factor.
