Abstract | The utility model discloses a pressing clamping type jet reverse circulation coring drilling tool which comprises an upper connector, an outer pipe, a negative pressure device, an inner pipe and a drill bit. The coring gripper is arranged at one end, facing the drill bit, of the inner pipe in a sleeving manner so as to grip a rock core; one end of the negative pressure device is fixedly connected with the upper joint, the other end of the negative pressure device is fixedly connected with the inner pipe, and the negative pressure device is used for forming negative pressure to suspend the rock core in the inner pipe; when coring operation of a target rock stratum needs to be carried out, the side, away from the drill bit, of the upper connector is fixedly connected with a drill rod, torque is conducted and transmitted to the drill bit through the outer pipe, and therefore the pressing-clamping type jet reverse circulation coring drilling tool rotates to achieve drilling, local reverse circulation is establish |
