Cyclic impact on productive formations of high-viscosity oil deposits

Abstract

Abstract It is shown that the priority condition for reliable forecasting of the cyclic impact on productive formations of high-viscosity oil is the joint research and study of rheological and filtration properties of high-viscosity oils, including thixotropic properties, as well as mathematical calculations to choose the right mode of the working fluid injection. For the Stepnoozerskoe field conditions, the optimal injection period is 10 days.
