METHOD OF DEPRESSION CREATION IN BOTTOM-HOLE ZONE OF PRODUCTIVE FORMATION BY CRYOGENIC METHOD

摘要

FIELD: oil and gas industry.SUBSTANCE: method includes field equipping with a cryogenic unit, development of disturbing and production wells, and stimulation of the influx to the production well by depression creation through the disturbing well. The depression is ensured during coolant circulation via the well bore, due to this the formation and contained in its pores fluid are cooled. This results in the active compression of hydrocarbons around the disturbing well.EFFECT: increased efficiency of the fields' development.
