油田开发过程中碎屑岩储层预测

随着油田开发的深入,储层预测的变得越来越重要,其准确性对提高油田开发效率、预测剩余油分布具有重要的影响。利用高分辨层序地层学理论,建立了塔中志留系塔塔埃尔塔格组高精度的等时地层格架;根据岩心、测井和三维地震等资料进行沉积微相精细分析,确定沉积微相的展布,发现砂岩、砾岩富集的沉积微相的展布规律和形态特征。在上述条件的约束下,建立了储层三维地质建模并对于有利层位进行了流动单元研究。

Prediction of Clastic Reservoir during Oilfield Development

With the progress of oilfield development, prediction of reservoirs become more important, its accuracy has important significance of enhancing the efficiency of oilfield development and remaining oil distribution. The theory of high resolution sequence stratigraphy is used to establish a high precision isochronism stratigraphic framework for Silurium Tataaierta Formation. Based on the data of core, logging, 3D seism, precision analysis is conducted on sedimentary microfacies for purpose of establishing the sedimentary microfacies distribution and clarifying the distribution rules and shape of sedimentary microfacies enriched with sandstones and conglomerate. Constrained by these conditions, a 3D geologic model is established to study the flow unit of beneficial zones.
