Study on the Statics Analysis of Promoting the Drilling Efficiency of PDC Anchor Bit

Abstract:

PDC anchor bit has the very good rock fragmentation abilities with high penetration rate and long drilling time,which makes the drilling efficiency highly improved and the economic benefit remarkably increased.Now PDC anchor bit has been widely used in drilling field.But for the reason that it is sensitive to the formation characteristics and working conditions,it doesn’t achieve good performance in homogeneous formations such as conglomerate and interbeded sections.In order to reach the goal of enlarging the scope of PDC anchor bit application in oilfields,it is necessary to study the breakage mechanism in conglomerate formations and design the PDC anchor bit optimally.
