Method for Eliminating sobreoscilacion while Measuring a property of nuclear Magnetic Resonance Of geological formations surrounding a Borehole

摘要

The present Invention relates generally to a method for Eliminating the sobreoscilacion as measured by means of Resonance magnu00e9ticanuclear,Properties of a geological formation traversed by a Borehole. The medicionpuede be made during Drilling or using a cable in the Borehole.During a first time period of a unique sequence of impulses, the Measurement includes the desired spin Echoes and indeasados Effects, that is, lasobreosci anyThe Measurement noise and the change of the Base Line.During a second period of time a unique sequence of impulses, it eliminates the spin Echoes but does not eliminate the unwanted Effects.Using a Signal captadadurante is gundoperu00edodo Time signals measured during the first period of time are corrected to remove the component from the sobreoscilacion,Noise Measurement and the change of the Base Line.
