简介:在这研究,在Tang-eKushk和Sarvestan区域stratigraphic节的东方的Tarbur形成的465m被学习,185薄节被提供并且分析。基于岩石层位学的研究,在这二stratigraphic节的Tarbur形成被划分成上面、更低的部分。更低的部分包括是的中等床的rudist石灰石与Gastropoda由铁小瘤组成。上面的部分用轻灰巨大的organodetrital石灰石做的。两个都学习的节的识别有孔虫目动物由组成:Orbitoides媒介,Orbitoidestriangularis,Orbitoidestissoti,Orbitoidesorientalis,Orbitoidesapiculata,Antalynakorayi,Rotaliaskourensis,Dicyclinaschlumbergeri,Nezzazatinellasp,Omphalocyclusmacroporus,Trochospirasp,铁陨石calcitrapoides,Broeckinellasp,Lepidorbitoidessocialis,Gavelinellapertusa,被检测,并且也,它有Salpingoporelladinarica的Dasycladacea,Salpingoporellaturgida,Salpingoporellasp...根据诊断有孔虫类,Tarb的年龄决心

简介:延长组长6-2是鄂尔多斯盆地西南缘镇泾油田的一个重要勘探层位.通过岩心观察、测井资料、薄片研究、粒度分析,对镇泾油田长6-2沉积微相进行了深入研究.认为该区长6-2由一个完整的中期基准面旋回组成,水下分流河道主要发育在中期基准面缓慢上升初期和快速下降阶段,由于水下分流河道的强烈侵蚀作用,河口坝砂体不发育.中期基准面缓慢上升初期的河道具有深而窄的特点,砂体横向变化快,勘探难度大,而与之相对的是中期基准面快速下降阶段,水下分流河道具有厚而广的特点,为本区最为有利的勘探目的层.通过对不同可容空间下水下分流河道砂体厚度与河道宽度的研究,发现其具有很好的相关性,得出该区的砂体厚度与河道宽度的经验公式,为下一步勘探开发提供了强有力的理论依据。
