OPTIMIZATION METHOD FOR OIL PRODUCTION FROM MULTILAYER COMPOUND BEDS WITH THE USE OF DYNAMICS OF OIL RECOVERY FROM COMPOUND BEDS AND GEOPHYSICAL PRODUCTION WELL INVESTIGATION DATA Russian patent published in 2006 - IPC E21B47/10 

FIELD: oil production, particularly survey of boreholes or wells.

SUBSTANCE: method involves measuring pressure in separate bed zones and selecting method of pressure distribution profile calculation; calculating pressure value in central well bore zone with the use of above method of pressure distribution profile calculation and comparing calculated pressure values in central well bore zone with measured pressure values; constructing model of bed fluid pressure at well bottom on the base of method of pressure distribution profile calculation; comparing calculated pressure values with data concerning previous process progress, determining and selecting process of repeated well filling to obtain maximal output from each bed layer.

EFFECT: increased well producing ability due to reparation of non-stimulated, weakly stimulated well perforated intervals in multilayer compound bed or well perforated intervals having low output liable to repeated injection operation with the use of any repeated well injection method (including hydraulic fracturing, acid treatment, repeated perforation or drilling of one or several transversal drain holes).
