And the influences of temperature and salinity on foam properties were studied as well. The plugging ability,diversion ability,and oil displacement performance for SDS and SiO2+ SDS foam systems were characterized and compared by means of the core displacement experimental facilities. Also the microscopic visualization test was conducted to compare the oil displacement performance of water flooding,SDS and SiO2+ SDS foam systems on the dead-end pores. The results show that SiO2+ SDS foam system is more stable than SDS foam system,which can significantly improve the plugging,diversion,and oil displacement ability. Also the displacement effect for dead-end pores is increased as well.","PeriodicalId":35442,"journal":{"name":"Zhongguo Shiyou Daxue Xuebao (Ziran Kexue Ban)/Journal of China University of Petroleum (Edition of Natural Science)","volume":"38 1","pages":"124-131"},"PeriodicalIF":0.0,"publicationDate":"2014-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70187649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that the evolution order of paleoproductivity in Huadian Basin is middle oil shale member, upper coal member and lower pyrite member. The highest paleoproductivity achieves at 1 033.09 g/(m·a) during the sedimentary period of middle member of Huadian formation. The ancient lake is in eutrophic state. The bacteria and algae are dominate in organic matters and the lake water is in steady hypoxic and fresh-brackish reduction environment during this stage, which reflects that the high paleoproductivity is mainly contributed by algae and directly influences the origin and abundance of organic matters. The alternative salinity change of lake water makes the bottom water be in a steady hypoxic environment, which is a favorable environment for organic matter conservation. The lakes during the lower member and upper member of Huadian formation are in obvious mesotrophic state and fresh hypoxic environment, and the average paleoproductivity is 143.82 g/(m·a) and 153.26 g/(m·a) respectively. High paleoproductivity is the first condition for organic matter enrichment of oil shale, and steady hypoxic environment in bottom water is the most favorable environment for organic matter enrichment.","PeriodicalId":35442,"journal":{"name":"Zhongguo Shiyou Daxue Xuebao (Ziran Kexue Ban)/Journal of China University of Petroleum (Edition of Natural Science)","volume":"36 1","pages":"38-44"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70187395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
