The Design Technology of PDC Bit in The High Hardness and Abrasiveness Formation of Xishanyao
High hardness and abrasiveness, low ROP and seriously deviation are the features of Shanle block Xishanyao formation in Turpan-Hami Oilfield, whose lithology was conglomerate, glutenite, interbedded sandstone, large angle of bedding and many fractures. To enhance ROP at this high hardness and abrasive region, designing of PDC bit is introduced based on crown shape, blade, teeth, bit hydraulics and so on. The designed bit had a good performance in the test of Well He-3 at Shanle block.
