罗242井区侏罗系延9沉积相研究

Study on Sedimentary Facies of Jurassic Yan 9 in Luo 242 Well Area

综合利用测井、岩心和沉积构造的特点对罗242井区延9储层进行沉积微相研究,认为罗242井区延9期的沉积相为三角洲相平原沉积。进一步可以划分为分流河道、分流间洼地、天然堤等3种微相类型。沉积相平面分布的研究为该区储层精细描述奠定了基础。

Comprehensively using the characteristics of well logging,cores and sedimentary structures to study the sedimentary microfacies of Yan 9 reservoir in Luo 242 well,it is believed that the sedimentary facies of the 9th stage of Luo 242 well is delta facies plain.It can be further divided into three types of microfacies,namely distributary channel,diverting depression and natural embankment.The study of the distribution of sedimentary facies plane laid the foundation for the fine reservoir description in this area.
