Solid bitumen quantification and its application to resources evaluation of Changxing Formation and Feixianguan Formation in Puguang,Sichuan,China

XU Li-heng Exploration and Development Research Institute,Daqing Oilfield Company Limited,Daqing 163712,China  
There has not been a useful way in accurate quantification of the solid bitumen in reservoirs.The solid bitumen was quantitatively evaluated by analysing the TOC in the carbonate rock reservoirs of Upper Permian Changxing Formation and Triassic Feixianguan Formation,and the ancient oil reservoir crude oil content and its oil-cracking gas content were calculated by the material balance method (C and H).The result shows that the average bitumen content of Changxing Formation and Feixianguan Formation is 0.17% and 0.29%.The better of the reservoir quality,the higher content of the TOC (bitumen).The average TOC value of Type Ⅰ,Ⅱ and Ⅲ reservoirs is 0.42%,0.35% and 0.21%.The total ancient oil reservoir crude oil content of Changxing-Feixianguan Formations in Puguang is about 0.501×109 t and its total oil-cracking natural gas content is about 0.361×1012 m3.
