CONSTRUCTION injection well to displace the high-viscosity oil, low-temperature oil reservoirs UNDER PERMAFROST

摘要

The invention relates to the oil and gas industry. The technical result - an increase of reliability of the injection well construction for displacing heavy oil from the oil reservoir to the low temperature conditions of permafrost. The design of the injection well to displace oil from the low-temperature high-viscosity oil reservoir under permafrost comprises directing the conductor, with a production tubing string disposed therein tubing, liner-filter, suspended in the lower portion of the production string via the suspension device. Column tubing equipped with a telescopic connection, a circulating valve disconnector column, a packer, packer shank and the centering funnel. 1 yl.
