| 摘 要： | 通过对岩心薄片观察及多参数实验分析,认为塔里木盆地英买力地区丘里塔格组和蓬莱坝组白云岩的形成属于埋藏成因,岩性以细-中晶白云岩及颗粒白云岩为主,其他为泥粉晶白云岩和角砾白云岩,地球化学指标独特。结合古构造及成岩-孔隙演化史分析,埋藏白云岩化和埋藏岩溶作用是英买力地区丘里塔格组和蓬莱坝组白云岩储集层发育的主要成因机理。英买1-2三维地震工区油源充足,储盖层和输导条件好,气藏勘探潜力巨大。 |

| Abstract: | 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,and the lithology is dominated by fine-medium crystalline dolomite and grain dolomite,others are dolomicrite,crystal powder dolomite and breccia dolomite,with unique geochemistry index.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 3D seismic work area is sufficient in oil source,preferable in reservoir and cap rocks and good in fluid conducting conditions,therefore the potential for gas exploration will be great. |
