| 254 | Earth drilling apparatus | US38495373 | 1973-08-02 | US3889959A | 1975-06-17 | PERSSON JAN EDVARD |
| A drilling apparatus for pressure drilling through the earth, comprising a drill string, a casing tube assembly, a rotary drilling machine with mechanized drill string handling and a liquid handling system. The liquid handling system comprises means for controlling the casing tube pressure and the liquid level within the drill string during withdrawal and disconnection of the drill string. At disconnecting a drill string section, a pressure air impulse is introduced into the flushing channel thereof so as to lower the liquid level and thereby avoid liquid over-flow at the top of the casing tube. A back-flow restricting valve prevents rapid rising of the liquid level within the drill string. A preventer unit having a pressure balanced packing sleeve seals off the upper end of the casing tube; the contact pressure of said packing sleeve is automatically and continuously adapted to the actual casing tube pressure by means of a pressure responsive control valve which is arranged to release the packing sleeve from pressure in response to decreasing casing tube pressure.
