Abstract: The integration of general characteristics,homogenization temperatures, fluorescence and fluorescence spectrum of the organic inclusions from feldspar in the Ma-1 well reservoirs in the Malang depression indicates that the organic inclusions have the homogenization temperatures ranging between 60-90℃ and 120-140℃,correspondingly with the yellow fluorescence and blueish green fluorescence,respectively.The oil and gas from the reservoirs have gone through two phases of migration: Phase 1,hydrocarbon migration and accumulation as low-maturity oil,and Phase 2,the accumulation of hydrocarbons.These reservoirs in the Permian Tiaohu Formation are believed to be productive.
