摘要： Properties of a porous solid sample 19, which may be a core of rock taken from below ground are carried out using apparatus which performs both nuclear magnetic resonance (NMR) and porosimetry measurements. The apparatus has a magnet 11,12 providing a magnetic field and a radio frequency coil 20 for transmitting and/or receiving electromagnetic radiation so as to bring about NMR in the magnetic field, a pressure vessel 14, 15 to hold a sample 19 within the magnetic field, a supply of a non-wetting liquid connected to the vessel, means to apply pressure to the non-wetting liquid to force liquid into pores of the sample 19 means to measure applied pressure of the non-wetting liquid and means to measure volume thereof taken up by the sample. The pressure of non-wetting liquid may be increased in steps, using intruded liquid volume at each step to give a measurement of pore throat size using NMR at each step to give a measure of pore size such as diameter of equivalent sphere. The non-wetting liquid may be mercury and NMR may observe the Knight shift of 99 Hg.

摘要： Apparatus for examining a fluid-containing porous sample, by a combination of centrifuging to move fluid into, out of, and/or within the sample and NMR to monitor the amount of fluid present at locations within the sample has a magnet system to provide a magnetic field; and a centrifuge rotor comprising a holder (18) for the sample and mounted to move the sample within the magnetic field. The apparatus preferably includes gradient coils (16, 116) superimposing a magnetic field gradient onto a field provided by magnets (11, 12, 111, 112). At least one radio-frequency coil (20) is located on the centrifuge rotor in a position 10 which surrounds the sample in the holder. The coil axis is transverse to the magnetic field and field gradient when measurement is made. Consequently NMR measurement of the distribution of fluid in the sample can be made while the centrifuge is in motion.

摘要： A fluid flowmeter which uses nuclear magnetic resonance to determine quantities of flowing fluid(s) has a polarizing magnet system with magnets which are high temperature superconductors such as yttrium barium copper oxide (YBCO) or bismuth strontium calcium copper oxide (BSCCO) which are superconducting at liquid nitrogen temperature and provide a greater magnetic field strength than conventional magnets. This may allow the flowmeter to accept higher through flow rate and/or may allow observation of 23Na in an aqueous phase as well as 1H.

摘要： NMR logging in a wellbore is used to monitor an oil reservoir during oil recovery by miscible displacement. Diffusivity distributions found by NMR logging indicate whether one or two phases are present and composition of residual oil. Operation of the oil recovery procedure may be maintained or modified in response to monitoring of the reservoir.
