OIL FIELD DEVELOPMENT METHOD |
摘要 |
FIELD: oil production industry, particularly to develop oil deposits having flooded reservoirs with non-uniform permeability. ^ SUBSTANCE: method involves flooding reservoir; injecting oil-and-bitumen product plug in reservoir, wherein the oil-and-bitumen product is obtained via production wells from highly-viscous oil and bitumen fields; producing oil from productive wells. Samples of oil-and-bitumen product taken from j-production wells are previously analyzed to determine aliphatic property Aj thereof. Then aliphatic properties Aj of the samples are compared with that (An) of native oil. If Aj> An the oil-and-bitumen product plug is used for water-saturated reservoir zone plugging. If Aj< An above plug is used to stimulate difficult-to-recover oil displacement. Plugs of oil-and-bitumen products having Aj> An and Aj< An may be jointly injected in reservoirs characterized by non-uniform permeability. ^ EFFECT: increased efficiency due to usage of oil-and-bitumen product having predetermined properties and adapted to increase filtration resistance in flushed zones having high permeability and to improve relative oil permeability in reservoir zone having low permeability. ^ 3 cl, 2 ex, 2 tbl |
