METHOD OF OIL FIELDS WELLS SYSTEM TREATMENT Russian patent published in 1994 - IPC

FIELD: oil-extracting industry. SUBSTANCE: method of oil field wells system treatment provides for choice of areas of oil field, determination of wells interaction and treatment exercise. Determination of wells interaction is exercised by calculation of partial correlation between wells by oil and water flow rates in terms of absence of third wells influence and in terms of determination of presence of interaction between wells with factor of partial correlation exceeding critical value. Before wells treatment is exercised, reduced factor of drainage is calculated for each well, determine average factor of drainage for oil field with following mapping of oil field drainage according to values of reduced factor of drainage and choice of oil field area with minimum factor of drainage of oil-extracting wells. In the area insulating works are carried out on pumped in oil wells, reduced factor of drainage of which exceeds its average value. beginning with well with maximum reduced factor of drainage, and intensifying works on the rest pumped in wells, beginning with well with minimum reduced factor of drainage. Then they choose oil-extracting wells out of number of wells, that interact with pumped in wells, and carry out insulating works on wells with reduced factor of drainage by water exceeding average its value, beginning with well , that has maximum value of reduced factor of drainage, and intensifying works on the rest wells, beginning with well, that has minimum reduced factor of draining. Then similar operations are carried out on non-interacting wells and go to next oil field area with minimum factor of drainage of oil-extracting wells. EFFECT: method is used in oil-extracting industry. 1 dwg, 2 tbl
