长春岭油田储层预测研究
|
摘要
常用的储层横向预测技术有地震属性分析技术和地震反演技术两大类,应用这两种技术对长春岭油田扶余油层进行了储层预测研究.研究结果表明,长春岭油田地震资料的振幅属性与已知井砂岩发育情况吻合较好,本文利用振幅属性描述了扶余油层Ⅰ～Ⅳ砂组储层砂岩的分布趋势.应用地震反演方法得到扶余油层储层砂岩纵横向展布规律,经钻探证明,预测的结果比较可靠.
Commonly used lateral reservoir prediction technologies include seismic attribute analysis and seismic inversion.Reservoir prediction to Fuyu oil layers of the Changchun Ling oil field is studied by the two technologies.It shows that the amplitude attributions of the seismic data in the Changchun Ling oil field coincide well with the situation of sandstone development in wells.In this paper,distribution trends of reservoir sandstone are described by means of amplitude attributions in the Ⅰ～Ⅳ sandstone beds of Fuyu oil layers.The distribution laws of the sandstone reservoir in vertical and horizontal directions are also obtained by means of the seismic inversion.It is proved that the prediction result is much reliable by exploration drilling.
