Abstract:
Disclosed is an integrated apparatus and a method for long-distance downhole drilling and fracturing. The apparatus comprises a drill bit (06), a fracturing rod (05), a protective rod (04), a hole sealing rod (03), a high-pressure sealing drill rod (02) and a crawler drilling machine rod-feeding device (01), which are successively connected to each other end to end. In the method, while drilling, the drill rod (02), the fracturing rod (05), etc. are delivered to a designated position; a high-pressure water hole is provided in the crawler drilling machine rod-feeding device (01) so that high-pressure water enters the drill rod (02) through the high-pressure water hole and reaches the fracturing site, and fracturing is finished; and then, the drill rod (02) is withdrawn, only using a crawler drilling machine, from one fracturing hole to another fracturing point, and a hole-sealing operation is simultaneously carried out.
