【Abstract】 With the development of exploration technique, the contradiction of drilling speed and well cost widely existed in well drilling fields. For this,The present work was aimed at studying new methods of enhancing hydraulic energy and mechanical energy of rock cutting to improve the penetration rate of well drilling by using combination drill string and drill bits with new-style nozzles. At the same time, some key problems on the study and application of hydraulic effect for deep hole drilling were discussed. Several effective hydraulic ways which would enhance the penetration rate of deep well drilling were evaluated and investigated.更多还原
