    • For the strata with features of extreme hardness, strong abrasiveness, high frequency of interbedding, with quartz and gravel interlayer, PDC bit is barely to be employed as a result of low ROP and service life, embodied as fast wear of working layer, easily breaking of diamond compact, etc. The roller bit is not suit for this kind of strata either, and drilling accident might be caused by losing teeth. To solve this problem, the pulsing impregnated petroleum bit with low-temperature electroplating is developed, and numerical simulation is employed for the hydraulic performance of bit flow field. Field applications show that this kind of new bit enjoys the advantage of long service life and high ROP.
