Diamond test and demonstration machine - New products, new technology, drilling in complex formations achieved good results.
In the "Anben" area, the No. 1 rig has solved the problem of forced inclination and full hole leakage in phyllite formation, and the final hole depth is 2018.5 meters. Unit 3 solves the related problems of wire-line coring drilling in oil and gas well construction. The H-bore has a diameter to the end, takes 80 days, and the final hole depth is 1800.63 meters.
