METHOD FOR ASSESSING THE IMPACT OF MAN-MADE FACTORS ON CHANGES IN THE COMPONENT COMPOSITION AND PROPERTIES OF FORMATION FLUID IN THE BOTTOMHOLE FORMATION ZONE Russian patent published in 2018 - IPC E21B49/00 G01N30/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas production industry, namely to methods for designing field development with a reservoir pressure maintenance system, and can be used to justify and predict changes in the composition and properties of formation fluid during the operation of the deposit. Technical result is achieved by simulating the interaction of formation fluid with injected water under conditions simulating the real operating mode of the well, with the help of a layout of laboratory equipment consisting of a phase behavior setting, volume high pressure pump, high pressure samplers with a floating piston of at least 700 cm³, densimeter, electromagnetic viscometer, vacuum pycnometer, gas meter, chromatograph.

EFFECT: increase in accuracy of forecast of changes in the component composition and properties of the reservoir fluid during the exploitation of the deposit, taking into account the stage of development of the deposit, in particular, such parameters as gas factor, density, viscosity of oil, calorific value of gas, content of target components.
