This invention discloses a method for coring ultra-deep cutoff walls. First, a mud pump is activated to deliver special plant-based adhesive mud. A large-diameter double-tube drill bit equipped with a diamond drill bit is used to drill and extract the core at low pressure and slow rotation. After drilling to the predetermined depth, the mud pump is shut off, and a cable winch is used to lift the drill bit. A continuous steel borehole pipe of equal diameter is installed at the bottom. The drill bit is then replaced with a small-diameter double-tube drill bit equipped with a diamond drill bit, and the mud pump is activated again. A segmented drilling and coring cycle process is employed. During drilling and coring, borehole inclination is monitored based on a preset inclination measurement frequency. If deviation occurs, a new drill bit and an extended drill bit are used to repeatedly sweep the borehole at low pressure and slow rotation, inject cement grout, or use a deviation correction device for dynamic correction. By optimizing the drill bit combination and coring parameters, the core recovery rate is ensured to be no less than the preset value. This invention effectively solves the technical problems of easy deviation, low drilling efficiency, low core recovery rate, and poor integrity in ultra-deep cutoff wall drilling, providing reliable technical support for the quality assessment of ultra-deep cutoff walls.
