A Critical Tool for Cement Laboratories
The Model 4262 Twin Cell UCA is the workhorse for compressive strength determination in busy laboratories. With two cells that can operate independently of each other, the Model 4262 is a must have for laboratories conducting standard oil well cement testing.
Designed specifically for the busy laboratory, the Twin UCA will handle the everyday testing with faster turnaround time and less lab space. The cell is much easier to handle making it more user friendly than the large UCA cells designed for more extreme downhole conditions.
A Proven, Reliable Technique
Cement strength is determined by measuring the change in velocity of an ultrasonic signal transmitted through the cement specimen as it hardens. As the strength of the cement specimen increases, the ultrasonic signal’s transit time through the sample decreases. Using proprietary algorithms that have been proven throughout the industry, the relative strength is calculated.
Operational Simplicity
The cement slurry to be tested is prepared in accordance with API recommendations, then placed in the unit’s temperature and pressure-controlled cell which simulates the curing conditions that are expected downhole. During testing, temperature is automatically controlled while pressure is manually set.
The acoustic measurements are read by an internal computer which automatically performs the complex strength calculations. All test data including the compressive strength results are then transferred to a Windows capable computer, running Chandler Engineering Model 5270 Data Acquisition Software. The software produces real-time graphs of the calculated strengths, measured temperatures and transit times.
