METHOD FOR CONTROLLING DISPLACEMENT OF PUMPED OR CONTOUR WATERS DURING EXTRACTION OF OIL AND GAS DEPOSITS

摘要

FIELD: oil extractive industry.;SUBSTANCE: displacement of front limits of pumped or contour waters is determined from data of vertical seismic profiling performed no less than two times. Each time identity of excitation conditions and oscillations receiving and observation system is maintained. Data for excluding remaining non-identity of excitation conditions and oscillations receiving are processed. Seismologic cross-sections are built, difference between them is calculated, which shows changes of front of pumped and contour waters.;EFFECT: simplified realization, lower costs.;3 dwg
