| Abstract: | On the basis of analyzing the current drilling methods, a controlled penetration per revolution (PPR) is suggested to be used to control drilling process.Several impregnated diamond real bits and micro bits were experimented under the pattern of PPR in the laboratary. Deponding on PPR and PPR per bit weight, the reliable PPR region could be got to different types of rock and bits, and optimal bits could be selected to different types of rock. Drilling can be controlled under this region. |
