Product Description Company Profile

1. Product Introduction of Differential Sticking Tester NF-2

The instrument is mainly composed of bracket, mud cup, tee, pressure cylinder, etc.

The instrument has the characteristics of compact structure, high measuring precision and convenient operation. It has been widely used in oil fields, scientific research institutes, laboratories and other departments.

2. Working Principle of Differential Sticking Tester NF-2

The instrument works with the parameters determined by simulating the actual situation of deep well operation. The QG80 manifold provides stable pressure to the drilling fluid to obtain the filtration and the filter cake formed after filtration, then presses down the adhesion disk to make it stick with the filter cake, and measures its adhesion coefficient (at normal temperature) with a torque meter.
