Established is suitable for the wild potassium drilling site fast analysis of slurry supernatant K.B r.S r element energy dispersive X-ray fluorescence spectroscopy (EDXRF) method and practical application in the field of potash jianglin depression exploratory well drilling process on site. The precision of the method RSD (n – 1) is better than2.28%, the calibration curve correlation coefficient were greater than 0.9991, the standard addition recovery is 95.5% ～ 103.0%, 6 basic meets the requirement of allowed limit. Of 200 ～ 800 m depth interval of 20 mud samples at a set interval measurement results with lab 1 CP – AES almost the same methods can be used in potassium drilling field K in the mud, Br. Sr indicator elements such as rapid monitoring, provide data support for the decision-making of drilling
