一、Overview
This instrument is a simulated test analysis instrument, which is mainly used to monitor the friction coefficient between the drilling tool in the deep well and the well wall drilling fluid, so as to process the drilling fluid in time, improve its lubrication performance, prevent the occurrence of jamming drilling accidents, and provide accurate and reliable data to ensure fast and safe drilling. It has the characteristics of compact structure, high test accuracy, easy operation and so on. It is widely used in various oil fields, scientific research institutes, laboratories and other departments.
二、Model and specification
1. NF-1: Adhesion factor tester No cylinder assembly
Features: The adhesion between the adhesive plate and the filter cake depends on the pressure exerted by the pressurized rod.
2. NF-2: Adhesion factor tester Assembly with pressure cylinder
Features: The adhesion between the adhesion plate and the filter cake is exerted by air pressure on the pressurized cylinder.
三、Main technical parameters
1. The diameter of the adhesive disk is φ50.7 mm
2. Working pressure 3.5MPa
3. The maximum pressure of the drilling liquid cup is 5MPa
4. Filter area 22.6cm2
5. Gas source: nitrogen and carbon dioxide gas (excluding oil, water and other impurities) (oxygen is strictly prohibited)
6.Its rated pressure should be greater than 5MPa
