摘要： An apparatus and method for estimating a parameter of interest of an earth formation, particularly relating to borehole logging methods and apparatuses for estimating electrical resistivity properties using at least one transverse toroid. The apparatus may include one or more transmitters for introducing electrical current to the earth formation. The transverse toroid may detect responsive electric signals from the earth formation at one or more frequencies and provide data from one or more depths of investigation. Further multiple transverse toroids may be used for detecting electric signals from a larger azimuthal range than a single transverse toroid. The method includes steps for using the apparatus to obtain data that may be used to estimate the parameter of interest.

摘要： Estimates of ringing produced by short recovery pulse sequences (CPMG or modified CPMG) are used to improve the effects of ringing in a conventional CPMG or modified CPMG sequences. This is an effective method for removal of ringing when the ringing is varying over a time interval that would be spanned by a phase alternated pair of conventional sequences. By use of frequency dithering, ringing due to the excitation pulse and the refocusing pulses can be removed.
