Oil well drilling geological X-ray fluorescent debris logging method

An X-ray fluorescence debris recording method of oil drilling geology is characterized in that: it contains the following steps: 1. sample from shallow to deep continuously on the drilling depth to get the debris samples of each drilling depth rock formation. 2. Clear the debris samples of each drilling depth rock formation on the drilling depth and dry these debris samples. 3. Grind the debris samples to powder and put them into the pressing die. Press the powder to print by using the tablemachine under the vacuum. 4. Test the component data of the print sequentially by using the energy dispersing-type X-ray fluorescence analyzer on the drilling depth. 5. The computer system makes the rock component data to the atlas on the drilling depth. Based on the analysis of the data and the atlas, the decision of the drilling lithologic characters and horizon is achieved. The distinct effects of this invention are: the cheap price, the low testing cost, the shorter analysis cyclic, the rock structure can be achieved s
