摘要：

青海油砂山油田上新统下油砂山组底部,K2-K1-3标准层之间的分流河道砂体,构成三角洲平原迷宫式储层骨架。地面露头的砂体骨架原型,可作为建立地下预测模型的根据,即可利用油田地面露头调查获得的宏观储层结构、砂体密度、砂体几何形态(主要是宽厚比)、区域古流向,以及露头区砂体骨架原型模型中,提取的总砂体面积比和不同厚度砂体面积比等地质信息,建立地下砂体骨架横剖面预测模型、砂体骨架平面预测模型、渗透率分布模型。预测青海油砂山油田目前的井冈,仅控制了1/2的分流河道砂体,仍有1/2的储层砂体尚未钻遇。这一结果为调整开发方案,提供了重要依据。

Abstract:

The diffluence channel sand bodies of K2-K1-3 key horizones placed on the bottom of Pliocene lower Youshashan Formation in Youshashan Oilfield,Qinghai have developed into a deltaic labyrith reservoir frame. The frame prototype of outcropped sand bodies may be considered as the evidence in establishing underground prediction model.This means that data obtained from outcrops of the sand bodies including reservoir structure,the density and geometry(the ratio of width to thickness)of the sand bodies,regional paleocurrent direction,the ratio of total areas of prototype frame models of outcrops,the ratio of the area for sand bodies with different thickeness were used to establish the predictive transverse model, predictive plane model and permeabality model of the sand body frames.According to the prediction results.half of the reservoiring sand bodies have ever beed drilled yet.
