Due to the increase of buried depth and the uncertainty of formation, the drilling speed and efficiency are greatly hindered, among which the bit selection of some complex layers is difficult, which is mainly reflected in the low stroke drilling speed of conventional bit, many times of starting and falling drilling, difficulty in orientation and other aspects.

In view of the complex formation, poor drillability, soft and hard interlock, difficult orientation, easy to release pressure, our company developed a variety of sizes, models, performance of the mixed bits can be selected, the use of mixed bits can more effectively improve drilling efficiency, shorten the drilling cycle.
