METHOD OF DEVELOPMENT OF OIL POOL Russian patent published in 2010 - IPC E21B43/16 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil-and-gas production field, and it is used in development of hydrocarbon deposits, complicated by availability of areas with different with different shaliness. Method includes sampling of oil through producing well, pumping of working agent through input well and sealing of wells mesh, drilled in the process of development. There are explored densities of drilling mud solutions, used at drilling of wells of initial mesh, and wells of compressing drilling, there are explored filtrational-tank behaviors of beds according to geophysic materials of the primary and following drilling and its possible changing from mudding of infused clay in the drilling process and at pumping of working agents, influencing on swelling of natural clay in bed. According to changing of porosity, strata pressure and productivity factor it is sustained conclusion about presence or absence of clay in borehole environment in the bed. According to sustained conclusion it is assigned working agent, operation of development and methods of increasing of recoverable oil.

EFFECT: increasing of deposit oil recovery.
