Production Stimulation by Controlling the Properties of Clay Minerals During Oil Displacement by Water in Clay Reservoirs

  • S. V. Aghalarova

摘要

A technological method of alternate application of fresh and brine waters for intensification of involvement of residual oil reserves in development during oil displacement in clay reservoirs and a hydrodynamic model of predictive assessment of real mechanisms of the indicated intensification are proposed. An increase in oil production with the use of the proposed method as a result of ensuring blocking of watered zones by regulating clay content of the rock and water flow direction to less developed (slightly-low-permeable) sections of the reservoir is established.
