Comparative tests of 30% of UBS-bit in September, 2008 at LebGOKe showed good hardening and cementation shells rolling cutters, both experienced and serial bits to upgrade them by working with the PTA effect, which led to a substantial increase in drilling performance. Therefore, after being subjected to the compared pairs missing "Plasticine" feeble effort corps rolling cutters, as was found in the test 30% of UBS-bit at the Petrovsky Career Central GOK, in December 2009.
Data for the comparative testing of prototypes modernization rock bits 244.5 OK-PRT SH2.33UN1-UM-UBS1 (version 1,0% UBS), manufactured under U.S. patent number 7195086 and serial bits 244,5 OK-PRT SH2.33 UN - 1M, construction Gormash, ...
It is for the first time in the world that inventors of “Anvik” LLC developed the “Theory of dynamic interaction of the cutter bits with borehole bottom in the process of drilling”, which allows to have a feedback, that is according to the wear of the worked out cutter bits it will be possible to improve design of the bits. The concept of inventors of “Anvik” LLC is that wear of the bearing part of the rolling cutter bits was a little faster than wear of hard alloyed equipment of the teeth of the cutter bits.
