DEVICE FOR OIL DISPLACEMENT FROM HORIZONTAL WELL Russian patent published in 2011 - IPC E21B43/24 

Abstract RU 2418161 C1

FIELD: oil and gas industry.

SUBSTANCE: device consists of casing pipe lowered into horizontal well and cemented to horizontal section. Horizontal well is equipped with production string inside which tubing is arranged. Production string is provided with outlet channels on the end of horizontal section and inlet channels at the beginning of horizontal section. Packer is installed between production string and tubing. Production string is equipped on the outside between inlet and outlet channels with inflatable packer interconnected with inner space of production string on the side of wellhead from packer, and additional packer isolating the well space above horizontal section. Inlet channels of production string are interconnected with tubing, and outlet channels of production string are interconnected with intertube space through process valve. The latter consists of housing with inner hollow connection pipe in which radial channels divided with partition are made. Radial channels arranged from partition on the side of outlet channels of production string are covered with annular piston spring-loaded to the direction of wellhead; and annular piston has the possibility of longitudinal restricted movement in housing with spring compression and opening of radial channels.

EFFECT: increase of surface area of warming coverage of productive formation owing to thermal-physical and vibration-wave impact on productive formation with working agent.
