Investigating of probe polarizing field of nuclear magnetic logging

The study is concerned to the polarizing field of a nuclear-magnetic coil with finite geometric dimensions of the winding. An assessment is made regarding the possibility of idealizing the winding form. A general comparison is given for the polarizing field of the probe with finite geometric dimensions. An analysis of the nuclear-magnetic coil probe fields was performed by this equation to show the possibility of disregarding the input of the coil short sides. It was also shown that a probe coil in the form of an annular sector (2 delta = 120 deg) provided the most profound insight into the problem possibility of using interpretation pallets calculated in allowing for a distance-dependent quadratic variation in the polarizing field voltage
