Instrument Features
The equipment provides higher experimental temperature and pressure, simulating the reservoir environment in deep well drilling;
Simulates the drilling and tripping processes during actual drilling, resulting in more realistic data;
The two-way balanced pressurization system can effectively eliminate the influence of equipment system friction on the experimental results;
The data from the specially designed core model test is closer to the actual field conditions.
Instrument Functions
Simulate the sliding friction and rotational friction between the drill string and the rock and drilling fluid during the drilling process under the conditions of formation temperature and pressure, with drilling fluid circulation or static conditions;
Simulate the filtration loss of drilling fluid during the circulation process under the conditions of formation temperature and pressure, and simultaneously measure the sliding friction and rotational friction between the drill string and the filter cake.
