Model 4268 ES Cement Expansion / Shrinkage Cell

Model 4268 ES Cement Expansion / Shrinkage Cell
A Critical Tool for Oil Well Drilling and Cementing
The expansion or shrinkage of oil well cement during curing can positively or negatively impact the integrity of a competed well. The Model 4268ES Cement Expansion / Shrinkage Cell is an option to a Model 5265 Static Gel Strength Analyzer (SGSA), Model 4265 Ultrasonic Cement Analyzer (UCA) or Model 4265H UCA. When combined with a precision pressure controller, the system continuously measures the expansion or shrinkage of a cement sample under high temperature and high-pressure conditions.

The system measures the change in volume of the sample using a diaphragm and displacement piston combined with a precision LVDT. The resulting translation of the piston is scaled in units of milliliters (mL) or percent expansion. Test data is presented graphically by the Chandler Engineering Model 5270 Data Acquisition and Control System.

The Model 4268ES Cement Expansion/Shrinkage Cell makes use of the programmable temperature controller that is a part of existing Chandler Engineering Ultrasonic Cement Analyzers and is available for use with Models 4265 UCA, 4265-HT UCA, or 5265 SGSA. A Quizix Pulse Free Precision Pump is also required when using the Model 4268ES.
