I． R&D background
The former structure of the electrical stability tester is mainly composed of external host, electrode, power supply and battery, which is inconvenient to carry and limited to field use. Therefore, the instrument is placed in the instrument box to provide favorable conditions for the use of the outdoor environment.
II． Product introduction
The electrical stability tester is a portable instrument for measuring the electrical stability (ES) of oil-based drilling fluid. The electrical stability of drilling fluid is related to the stability and wettability of emulsion. The tester is in accordance with the electrical stability test procedure described in API rp13b-2 Recommended Practice for field testing of oil based drilling fluids.
The instrument is mainly composed of instrument box, test body, electrode, power adapter and glass beaker.
The electrical stability tester is a sine wave instrument, which is used to measure the relative electric strength of drilling fluid with continuous oil phase in conventional field and laboratory. It is accurate, simple and portable. The influence of chemical composition and shear history of drilling fluid on the absolute value of ES is very complex. Therefore, it is not advisable to interpret the oil wetting state of drilling fluid based on single measurement of es. When determining the treatment process of drilling fluid, only can use the change trend of ES.
Characteristic:
AC power plug to allow general operation of power supply requirements
Power supply: 16V 4.5a (power adapter)
Auto calibration, real time performance check
The monitor is large and easy to read
