Diamond drilling core bits key technologies for knowledge sharing

Diamond core bits are widely used in mining and drilling industry , and the staff conducting these drilling work, not only for the quality of these devices are required , you should know some drilling technology. Mastering the technique can effectively improve the efficiency of mining personnel. Ramada mining machinery manufacturers and content to share with you some tips on drilling .
 An efficient rock breaking technology : drilling a borehole in order to form a rock formation , and therefore, efficient rock breaking technology to improve drilling speed and shorten the construction cycle , the key to reducing the cost of drilling in deep and ultra deep wells and large displacement wells, due to the tripping time accounted for a growing proportion , with deep hardness and abrasive formations are also increasing, making efficient rock breaking technology in deep and ultra deep wells and large displacement is particularly urgent .

    Second, the well trajectory technology : Because of heterogeneity and anisotropy of the rock, drill drilling will be affected in the formation of ground forces . Irregular movement wellbore instability and increase the drillstring trajectory prediction difficult. Control theory is introduced into the wellbore trajectory and control, ground remote variable bending joints and adjustable stabilizer been developed . Rotary steerable drilling system .Third, carrying rock technology : the broken drill cuttings from the bottom to clear out in time to improve the penetration rate , the key to reducing drilling accidents. In highly deviated wells, due to the debris in the borehole gravity fall to the lower side , the impact of drilling activities in the column , increasing the friction torque of the drill string , but also easily lead to the underground complex situations .
 Fourth, wellbore stability technology : the formation is opened, it lost the original rock wall supporting force , if the wall rock intrinsic bond strength is weak, instability will collapse ; Some formations of shale formations easy drunk swelling collapse ; some formations such as salt formation prone to creep ; some rock formations such as salt can cause fluid performance deteriorates , resulting in downhole . Wellbore stability problems is an urgent need to solve the problem, which seriously hampered the development drilling .
