针对松辽盆地葡萄花油层三角洲沉积薄互层储层的特点, 研究不同微相的砂岩与测井特征、地震属性的关系, 探讨利用沉积微相、波形特征定性预测砂岩储层发育带的技术。利用地震属性预测技术定量预测储层厚度结果表明, 本区整个油层砂岩总厚度与地震属性有很高的相关度, 厚砂层的预测符合率较高。

In accordance with the characteristics of Putaohua oil reservoir of thin deltaic interbeded sedimentary layers in Songliao basin, we study the relation among sandstones of different microfacies log characters, and seismic attributes to try qualitatively predict the sandstone reservoir development zone in terms of sedimentary microfacies and waveform characters. It is concluded that there is high degree of correlation between the total thickness of sandstone oil reservoir and seismic attributes. Thick sandstones can be predicted with high reliability and the thickness of sandstone reservoirs is predicted.
