Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to pulmonology, and can be used for prediction of unattainable control of bronchial asthma (BA) in patients with osmotic hyperresponsiveness of respiratory tract in warm season with high relative humidity of atmospheric air. In the warm season of the year with low relative humidity of atmospheric air of less than 70%, the patient undergoes a bronchial challenge test with ultrasonic inhalation of distilled water (IDW). Amount of forced exhalation is calculated in % of initial values 1 second before and at 1st minute after IDW test. Discriminant function (D) is then calculated. Obtained D value is compared to the limiting value equal to 17.86. If D is equal to or greater than the limiting value, the patient is not predicted to achieve control of the disease in the warm season of the year. If D is less than the limit value, BA control in the warm season is predicted. 
     EFFECT: invention allows predicting unattainable control of bronchial asthma in patients with mild persistent and moderate BA course with osmotic hyperresponsiveness of respiratory tract.

Granted: 2021-08-12
Abstract: FIELD: oil industry.  
     SUBSTANCE: invention relates to the oil industry, in particular to methods for regulating the development of an oil deposit, and can be used to determine the optimal injection and selection modes for a group of wells for a deposit or its section. The method includes taking oil from producing wells, pumping water into injection wells, maintaining the bottom-hole pressure at producing wells above the pressure of oil saturation with gas, and at injection wells below the pressure of hydraulic fracturing, measuring the technological modes of well operation, removing pressure recovery curves, determining the filtration parameters of the reservoir. For each of the wells, taking into account their interference, the partial derivative of the total oil flow rate for the deposit is determined by the bottom-hole pressure during depression and repression. Then, using the partial derivative of the total oil flow rate by bottom-hole pressure, a dependence graph of total oil production is calculated and constructed from the sum of the absolute values of depression and repression, according to which the characteristic bend is determined and the optimal bottom-hole pressure and total oil production corresponding to the characteristic bend on the graph are realized. For optimization, only those reacting production wells are selected whose parameters of the initial recoverable reserves differ from those initially determined by calculations by 25% or more. After determining the optimal bottom-hole pressure and total oil extraction and changing the operating modes of these wells, the volumes of extracted oil for each of the selected producing wells are compared before and after optimization, based on which the required volume of injected water is calculated using a mathematical formula.  
     EFFECT: method makes it possible to increase the oil recovery rate for a given deposit by increasing the comparison of the parameters of the selected site that affect the volume of oil displacement, including comparing the characteristics of the deposit before optimization and after it for each producing well.
