Development of an NMR system for down-hole porous rocks
Nuclear magnetic resonance(NMR)has been widely employed in the petroleum industry.as oil and gas reservoirs are typical complex poraus media.Down-hole NMR measurements(thousands of meters below the surface)face the challenges of high temperature,high pressure.strictly limited size of instruments and high speed tool movement.All these challenges make the probe design spectrometer manufacture,data acquisition,data processing and interpretation quite different from desktop NMR measurements in the laboratory.In this paper,we present our recent development on the key technologies and implementation of an NMR system for down-hole porous rock applications.The techniques used in developing the down-hole NMR tool have not only been used in oil and gas exploration,but also can be adapted to physics,chemistry,materials,agricultural,food science non-destructive analysis.
