Jianghan Oilfield Jiangdui Co., Ltd. successfully prototyped a metal bearing sealing drill bit in the past, which showed good results in the extremely poor drillability of Daqing Oilfield. Compared with the drills previously used in the formation, the new drills have a longer life and more footage, and can effectively prevent the drill bit from breaking and other problems, and achieve the expected design goals.
It is understood that Jiang Drill has developed a single metal sealing technology based on bimetal sealing technology, and successfully applied to 7 small size specifications and more than 10 types of roller bites to fill the company's small size single metal sealing cone The blank of the drill bit.
