The three-phase saturations of oil, gas and water system in cores are importam data for analyses and calculations of oil-field. According to the principle that microwave energy through a core is strongly absorbed by water content, while oil, gas and sandstone are relatively transparent, the microwave instrument for determining multi-phase saturations in cores with oil, gas and water is introduced. The attenuated signals proportional to water content are promptly processed, calculated and displayed by a signal processing unit. Results of measurements are displayed in digits in terms of percentage. The instrument is featured by its small size, simple structure and low cost. It has been used for measuring mufti-phase saturations of cylindrical cores with oil, gas and water. The measuring error is within土3.0%.
