The Differential Sticking Tester
1. Summary
The instrument is a kind of simulating test analyzer. It is mainly used to monitor the coefficient of friction between the drilling string and drilling fluids in deep wells so as to handle the drilling fluids and improve lubricity character in time, which can prevent effectively the accident of differential sticking occurring and provide accurate reliable data for ensuring fast and safe well drilling. It is characterized by its compact structure, high operation precision and convenient for use. The instrument can extensively applied in the oil fields, research institutions and laboratories, etc.
