TECH DATA OF YINHAI Rock Bucket 

The Advantage of YINHAI Core Barrel with Roller Cone Bits

1. The reaming bit consists mainly of four or more cones. The main cutting teeth are new wear-resistant alloys for tungsten carbide inserts . The new formula and the new process of high-quality tungsten carbide teeth improve the service life of the reaming drill. The guide is a cone drill bit or a scraper drill bit.
2. The bearing seal uses high-performance O-ring seal or metal seal bearing and special grease for imported drill bit.
3. Special inserts are placed on the outer diameter of the head to reduce the wear of the head during the formation of abrasives in directional and horizontal wells, prolonging the life of the drill.
4. The cost to replace a roller cutters is a fraction of the cost to replace a large tricone rock bit.

Drill Operating Procedures of YINHAI Core Barrel

1. Before running the core barrel, the flexibility of the mechanism must be checked at the orifice.
2. Bucket flaps must enter the hole when fully stretched. 
3. The initial drilling can not be pressurized, and then gradually pressurized after the backdrilling is stable. At this time, the core barrel should not appear to skip(move up and down).
4. If countersinking or stuck drilling occurs during drilling, stop pressurizing and do not use reverse drilling.
5. During the drilling, it was found that the slewing resistance suddenly increased. At this time, it can be preliminarily judged that the core has been broken, and it can be reversed 2 to 3 times, and the core barrel can be lifted.
6. During the drilling process, a sudden pressure loss is found, that is, there is no resistance when turning. You need to stop drilling immediately and check to prevent the rotating shaft from breaking.
