A METHOD OF LIMITING THE INFLOW OF BOTTOM WATER IN OIL WELLS

Abstract

The paper describes the method of isolation of bottom water inflow in oil wells. The method of isolation of inflow of formation water in the well, watered by water cone flowing into the near-wellbore area, is drilling is carried out from the main borehole of the stopped well into the productive formation with water intrusion into radial offshoots along the radiusbelow of the well perforation interval. They pump the waterproofing composition into referred radial offshoots with the creation of the waterproofing screen along the radius of the main wellbore. They leave the well for a period of reaction of composition injected under pressure and perform a subsequent well completion through existing perforations of the perforated interval.
