PROCEDURE BRINGING WELL TO OPTIMUM CONDITION AFTER REPAIR Russian patent published in 2003 - IPC

FIELD: production of fluid fossils, oil and gas industry. SUBSTANCE: invention refers to operation of pumps installed in wells. Procedure includes placement of well pumping equipment at rational depth and pumping of fluid into oil collection system. Down-hole pumping equipment in which pump operates under cyclic condition and has capacity at which rated production is by far higher than maximum discharge of fluid before repair is installed during repair for periodic formation of hydrodynamic pulses. In this case pump is positioned at depth securing least specific expenses per ton of extracted well product under cyclic operation. Operation time of pump under cycle of regular operation conditions after repair is assumed to be equal to functional of boundary operation conditions of pump, time and rate of filling of hole clearance and is found by analytical expression. EFFECT: reduced negative effect of killing and optimized production after repair of well. 1 cl, 4 dwg, 1 tbl
