PECULIARITIES OF SPIN ECHO RESPONSE PROCESSING IN A STRONG FIELD NUCLEAR MAGNETIC LOGGING TOOL
Problems of improving the signal-to-noise ratio for recording spin echo responses in a strong field nuclear magnetic logging tool by both hardware (analog input circuits) and software (digital response processing) means have been considered. Different designs of the input circuit in the spin echo response receiver have been compared, and the conclusion that a double-loop circuit should be preferable has been made. Different digital filters used to extract the spin echo responses have been compared, and the conclusion that a triangle window should be preferable has been made.
