METHOD OF AND SYSTEM FOR CONDUCTING A BOREHOLE GRAVIMETRY SURVEY

摘要

A METHOD Of AND SYSTEM FOR CONDUCTINGA BOREHOLE GRAVIMETRY SURVEYABSTRACTA borehole gravimetry system employs a pair of pressuretransducers 20, 21 for lowering into a borehole along with a boreholegravity meter 10. The pressure transducers 20, 21 are spaced apartvertically within a pressure sonde 22 for producing a pressuredifferential measurement of the wellbore fluid. A pressuredifferential measurement and a gravity reading is taken for each of aplurality of vertical locations within the borehole as the boreholegravimetry system is advanced through the borehole.
