"COMPACT X-RAY GENERATOR, TOOL TO DETERMINE AT LEAST A PROPERTY OF A TRAINING THAT CIRCULATES A WELL DRILLING, A METHOD FOR DETERMINING THE DENSITY OF A TRAINING WHICH CIRCUMS A WELL-PERFORMANCE PERFORMANCE THE OUTPUT OF AN X-RAY GENERATOR ". Equipment and method for determining the density and other properties of a formation surrounding a wellbore using a high voltage X-ray generator. One embodiment comprises a compact X-ray generator capable of providing radiation with energy of 250 keV and higher while operating at temperatures equal to or greater than 125 ° C. In another embodiment, the radiation is passed from an X-ray generator into the formation; The reflected radiation is detected by a short-range radiation detector and a long-range radiation detector. The output of these detectors is then used to determine the density of the formation. In one embodiment, a reference radiation detector monitors a filtered radiation signal. The output output of this detector is used to control at least one of the acceleration voltage and beam current of the X-ray generator.
