摘要：

根据岩芯、测井求取的渗透率和粒度中值等参数变化的特点,将冷东地区沙三段Ⅱ油组划分出正韵律(A)、反韵律(B)、复合韵律(C)和均质韵律(D)4大类20小类非均质模式。在4种沉积微相中,模式A,C,D分别在相Ⅳ、相Ⅱ、相Ⅲ和相Ⅰ中所占比例最高,模式B则在各微相中差别不大。从相Ⅰ到相Ⅳ砂砾岩厚度减薄,泥质含量增加,粒度中值变小,渗透率增加。从相Ⅰ到相ⅢVk值由小变大,非均质性逐渐增强,相ⅣVk值最小,非均质性较弱。

Abstract:

According to the variations in permeability and grain size mid value obtained from rook cores and well log,the second oil bearing set of the third member of Shahejie Formation in Lendong region,western Liaohe Depression could be divided into positive rhythm(A),reverse rhythm(B),composite rhythm(C),homogeneous rhythm(D) 4 heterogeneous models and 20 sub-type models.Within 4 sedimentary microfacies,models A,C,D hold the highest percentage in Ⅳ,Ⅱ,Ⅲ and Ⅰ facies respectively,whereas model B shows little difference in microfacies. From facies Ⅰ to facies Ⅳ,the thickness of sand gravel stone decreases,the content of argillaceous rock increases,grain size mid-value gets smaller and the permeability becomes bigger.The variation coefficient of permeability and heterogeneity increases from facies Ⅰ to facies Ⅲ,but that of facies Ⅳ is the smallest.
