Properties of light oil displacement in relaxed reservoirs in water drive regime

M.A. Jamalbekov

The paper presents the results of light oil displacement process in relaxed reservoirs in water drive regime. Computer calculation results of development process have been analyzed, features of relaxation changes of porosity and permeability influence on the main indexes of volatile oil fields development in mentioned regime in the result of reservoir bed deformation, researched. The process of light oil displacement in the well with set depression in relaxed and elastic formations are considered. Characteristic features of relaxation influence in changed permeability and porosity indexes on the process in case when the pressure in external boundary is permanent, are specified. Relaxation influence on the main indexes of light oil fields development despite high formation pressures in water drive regime is shown and the necessity of its consideration in mathematical modelling of filtration processes noted.
