【摘要】 采取层序地层学理论与测井约束反演相结合的方法,对东营凹陷坨163井区沙三段的砂体分布进行了预测。研究结果表明,坨163井区沙三段主要发育沙三段下亚段浊积扇沉积体系和沙三段中亚段、沙三段上亚段的扇三角洲沉积体系;沙三段下亚段沉积时期研究区的东部和南部发育多个浊积扇体,最大的一个位于坨710砂体附近,沙三段中亚段沉积时期在坨717—坨718和坨710井区附近发育2个较大的扇三角洲;运用稀疏脉冲反演软件Ja-son对该区储层进行了反演,并运用三维可视化技术等方法,预测了坨710、坨718、坨717、坨714和坨163等5个有利砂体。更多还原

【Abstract】 Sandstone distribution in the third member of Shahejie Formation in Tuo163 well block,Dongying Depression was predicted acca-ording to the sequence stratigraphy theory and logging constrained inversion method.Turbidite fan sedimentary system in lower Es3 and fan-delta sedimentary system in middle and upper Es,were recognized in Tuo163 well block.Many turbid fans developed at eastern and southern parts of the interested region in lower Es3 sedimentation period and the Tuo710 fan is the biggest one among them.Two big fan deltas developed near Tuo717-Tuo718 and Tuo710 well blocks in middle Es3 sedimentation period.Then Jason inversion software of sparse pulse was used to inverse Es3 reservoirs in this area and five sandbodies of Tuo710,Tuo718,Tuo717,Tuo714 and Tuo163 were predicted based on the utilization of three-dimension visualized technique.更多还原
