Electrical Resistivity at Overburden Condition

Grace Instrument사의 M9115 Electrical Resistivity System은 과부하 상태에서 암석의 전기 저항 (electrical resistivity)를 측정하도록 설계되었습니다. 과부하 조건에서 완전 또는 부분 염수 포화 코어 샘플과 염수 전기 저항에 대한 암석 저항을 측정합니다.

M9115 includes a hydrostatic electrical core holder, with a hand pump for confining pressure generation, and a confining and pore pressure control panel for core desaturation.

The resistivity measurement is based on two and four electrode method. Water wet ceramic is used to retain gas and let the brine go out of the core sample. A burette is uSed to measure the brine expelled from the core to determine core saturation.

• Resistivity Measurement: 2 and 4 electrode
• Core Length: Up to 4 in.
• Core Diameter: 1.5 in.
• Pressure: Up to 10,000 psi
• Temperature: Room Condition
