摘要
Based on the core and thin section observation and multiple parameters experiments,it is suggested that the dolomites of Qiulitage and Penglaiba formations in Yingmaili area in Tarim Basin belong to buried genesis.Combining with analysis of the paleostructure and diagenetic-pore evolution,the buried dolomitization and buried karstification are the main causes of development of dolomite reservoirs of Qiulitage and Penglaiba formations in Yingmaili area.It is concluded that Yingmai1-2 will be great potential for gas exploration.
