摘要/Abstract

摘要： 为定量刻画具有复杂叠置关系的储集砂体的时空分布特征，利用钻井岩心资料、测井资料和测试分析资料，在众多研究成果的基础上，基于砂层交错层层组的厚度参数，对高桥地区上古生界储集砂体叠置关系及砂体规模进行了分析。结果表明，研究区山西组-下石盒子组储集砂体叠置样式包括冲刷切割型（削截式河道砂体）、冲刷接触型（完整式河道砂体）和连续过渡接触型（孤立式河道砂体）。不同时期砂体平面展布特征不同，山西组储集砂体相对较窄，为条带状分布；盒8段以多期分流河道彼此叠置成的巨厚储集砂体为特征，砂体横向连片分布，平面展布规模大。通过岩心测量计算出山2段、山1段和盒8段河流满岸水深范围、单砂体厚度、单河道宽度及河道带宽度。其中，山2段曲流河三角洲河道带的宽度为700~1 500 m；山1段曲流河三角洲河道带的宽度为600~1 200 m；盒8下亚段辫状河河道带的宽度为1 000~2 000 m；盒8上亚段辫状河河道带的宽度为750~1 600 m。

Abstract: In order to quantitatively characterize the spatial and temporal distribution characteristic of superimposed reservoir sandbodies,drilling core data,logging data,and test data are integrated to analyze the superimposeition relationship and sandbodiesbody size of the Upper Palaeozoic in Gaoqiao region of Ordos Basin.The superimposition styles of sandbodies in the Shanxi-Xiashihezi formations in the study area include scouring-cutting type(truncated channel sandbodies),scouring-contact type(complete channel sandbodies)and continuous transitional contact type(isolated channel sandbodies).Distributions of sandbodies formed in different periods are different.Sandbodies in the Shanxi Formation are relatively narrow,showing a banding distribution.In contrast,the very thick sandbodies consisting of superimposed distributary channels of multi-stages in the 8^th member of the Shihezi Formation feature in laterally continuous and large scale distribution.Based on core measurement,we calculated the channel water depth range of bankfull stage,single sandbody thickness,single channel width and river width in the 2^nd member of Shanxi Fm,the 1^st member of Shanxi Fm and the 8^th member of Shihezi Fm.The rivers in meandering river delta in the 2^nd member of Shanxi Fm has a width of 700-1 500 m,the rivers in meandering river delta in the 2^nd member of Shanxi Fm has a width of 600-1 200 m,and the braided rivers in the upper and lower 8^th member of Shihezi Fm have a wide of 1 000-2 000 m and 750-1 600 m respectively.
