Title:
ADVANCED DRILLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/210396
Kind Code:
A1
Abstract:
The invention relates to an advanced drilling device formed from an externally threaded cone and cylinder, the cylinder having a left-handed thread and the cone having a right-handed thread. The cylinder contains two motors joined together on a ball bearing and vertically opposite each other, one motor rotating the cone to the right and the other rotating the cylinder to the left. The device can drill wells by itself, without using long pipes connected to the drill bit as used currently. The rotation of the threaded cone allows the creation of a distance, and the cone acts as a tap of the device. The handedness of the threads of the cylinder and the cone differs, providing torque and resisting the rotational torque resulting from the force of layers of rock and friction.
