METHOD OF DEVELOPMENT OF DEPOSITS OF HIGH VISCOSITY OIL WITH THE USE OF STEAM HORIZONTAL WELLS

摘要: FIELD: oil and gas industry.SUBSTANCE: invention relates to industry. Method for developing a high viscosity reservoir using paired horizontal wells includes constructing injection well in the productive formation production located lower parallel well, descent into of two columns tubing different diameters with placement ends intervals barrel, one or displacement end horizontally relative by at least 10 m, initial warming up pumping necessary inter-wellbore space deposit creation hydrodynamic coupling vapor volume, aging thermocapillary impregnation cooling wellbore, carrying out thermo-barometric measurements through geophysical studies well. Based on results these studies, zones extreme temperatures are identified wellbore Among zones, zone is defined change angle recruitment curvature not more than 2 degrees an electric centrifugal pump descending string equipped temperature pressure sensors fiber optic cable along entire length filter, further, steam selection products Initial heating carried calculated volume high-temperature exploration after below maximum pump. Pump installed transition between large small heating, during operation pump, monitored inlet. When reaches close it moved nearby corresponding conditions installing wherein supply points extraction point less m order avoid breakthroughs.EFFECT: acceleration commercial exploitation deposit, reduction energy costs, efficient products.1 cl, 1 ex
