METHOD OF AND SYSTEM FOR CONDUCTING A BOREHOLE GRAVIMETRY SURVEY

摘要

A METHOD Of AND SYSTEM FOR CONDUCTING A BOREHOLE GRAVIMETRY SURVEY A borehole gravimetry system employs a pair of pressure transducers 20, 21 for lowering into a borehole along with a borehole gravity meter 10. The pressure transducers 20, 21 are spaced apart vertically within a pressure sonde 22 for producing a pressure differential measurement of the wellbore fluid. A pressure differential measurement and a gravity reading is taken for each of a plurality of vertical locations within the borehole as the borehole gravimetry system is advanced through the borehole.
