A device suitable for downhole heating of oil and gas drilling and methods of use thereof

Abstract

The application relates to the technical field of oil and gas exploitation, and discloses a device suitable for downhole heating of oil and gas drilling, which comprises a first heating film, the inside of the first heating film is fixedly connected with a first magnet, the bottom end of the first magnet is provided with a second magnet, the inner bottom wall of the second magnet is fixedly connected with a fixing block, the outside of the second magnet and the fixing block is slidably connected in the inside of the first heating film, the inside of the first heating film and the second heating film is fixedly connected with a control module, the outside of the second magnet is slidably connected with a second heating film, and the outside of the fixing block is slidably connected in the inside of the second heating film. The first magnet and the second magnet are adsorbed to drive the fixing block to slide into the inside of the first heating film, so that the modularization series connection effect can be realized, the number of series connection modules can be flexibly increased or reduced according to the wellbore caliber, the well section length and the well type characteristics, and one set of modularization device can be adapted to various wellbore structures and drilling working conditions.
