METHOD FOR DEVELOPING OIL DEPOSIT WITH NONUNIFORM PERMEABILITY OF CLAY-CARRYING STRATA

摘要

FIELD: oil production, oil deposit development. SUBSTANCE: intermediate beds are subdivided into ones of high permeability and ones of low permeability, then mineralized within 5.0 - 350 g/l stabilizing water solution of polymeric substance of linear-cyclic structure is pumped in. Polymer concentration is directly proportional to clayiness coefficient and is chosen on the base of simulation and particular properties of natural clay carrying collector. Amount of pumped in solution is determined by formula presented in description. EFFECT: increased oil production. 2 tbl
