摘要
Drill core analysis is a necessary preliminary study to explore oil and gas field. This kind of drill core always contains high contents of K(12.30 mg/g), Na(15.04 mg/g), Al(28.83 mg/g) and Fe(11.13 mg/g) with large amount of organic matter. The method of decomposing organic matter in the drill core by microwave digestion with concentrated HNO3 and H2O2 and dissolving the silicates by HCl and HF acids was used. This method of microwave digestion has advantages of no sample loss, simple operation, less usage of reagents and is environmentally friendly, as well as being accurate, reliable and having a low detection limit.
