摘要

通过岩心观察、薄片鉴定、粒度分析及地震属性研究,建立了东濮凹陷濮城构造带沙三中亚段沉积相模式,针对研究区“高隆深洼”的地质特点,结合砂岩和泥岩波阻抗随埋藏深度的变化规律,提出了去压实波阻抗反演方法,在沉积相模式指导下采用该方法进行了储层预测。结果表明:研究区沙三中亚段沉积时期主要发育扇三角洲—湖相泥—滩坝沉积体系,其中兰聊断层下降盘陡坡带发育2个扇三角洲,濮城背斜带为滨浅湖滩坝沉积,储层预测结果揭示出砂体厚值区围绕2个扇三角洲以及濮城背斜带的2个坝主体分布,在2个扇三角洲之间局部发育较厚砂体,其他地区为砂体厚度低值区,砂体展布特征符合沉积规律。在濮城背斜带与濮城次洼之间的斜坡地区,发育的扇三角洲前缘砂体以及2个扇三角洲之间的滩坝砂体具备形成岩性上倾尖灭、砂岩透镜体油气藏的条件,为岩性油气藏勘探的有利目标。

Abstract

Through core observation,thin section identification,grain size analysis and seismic attributes research,the sedimentary facies model of Middle Es3  Formation in Pucheng tectonic belt,Dongpu Depression was established.According to the geological characteristics of “high uplifts & deep sags” and the rule of wave impedance inversion on sandstone and mudstone varing from different burial depth,the wave impedance inversion method of expressed compaction controlled by sedimentary facies model was put forward and used for reservoir prediction.The results showed that the sedimentary systems in the study area was fan delta,lacustrine mudstone and beach bar facies.Two fan deltas were developed in the down throw side of Lanliao fault and beach bar sands in shore-shallow lacustrine were found in Pucheng anticline belt.The result of reservoir prediction showed that sand thickness was bigger in the area where developed fan deltas,beach bar or area between the two fan deltas.Sandstone distribution was fit to the rule of sedimentation.Fan delta front and the beach bar between the two fan deltas in the slope area between Pucheng anticline belt and Pucheng Subsag were favorable to exploration where were easy to form up dip wedge-out reservoir and lenticular reservoir.
