COMPARATIVE ANALYSIS OF WELL LOCATION SCHEMES AT WATERFLOODING

The main aim of this research is the creation of program tool for quantitative and qualitative comparison of different schemes of well location applied at waterflooding: the estimates were supposed to be carried on the basis of solution of the problem of advancement of border of OWC in time. The achieved results may be used for designing of waterflooding of real oilfields. At the heart of program complex lies the model of infinite homogeneous layer of fixed thickness, the surface of which is covered by doubly periodic grating with upstream and blowing wells in their cells. For describing of the process of combined filtration of water and oil modified Weierstrass dzeta-function was used.
