摘要(Abstract)：

利用泥岩涂抹系数对苏仁诺尔断裂侧向封闭性空间分布特征进行研究认为,苏仁诺尔断裂在浅部地层内侧向封闭性好,在深部地层内侧向封闭性差。苏仁诺尔断裂在大一段、大二段地层内侧向封闭性好,在南二段仅Ⅰ340测线以南局部侧向不封闭或封闭性差,其余大部分地区侧向封闭,在南一段仅在Ⅰ360—Ⅰ420测线之间和x848测线以东地区侧向封闭性好,其余大部分地区侧向封闭性差。通过苏仁诺尔断裂侧向封闭空间分布与油气藏分布关系研究,得到苏仁诺尔断裂对油气聚集具有两方面的控制作用:①断裂侧向封闭纵向分布的差异性造成油气聚集层位的差异性;②断裂侧向封闭平面分布的差异性决定油气聚集沿断裂分布的差异性。
Study on spatial distribution of lateral seal ability of Surennuoer fault by mudstone smear coefficient indicate that the lateral seal ability of Surennuoer fault is better in shallow formations but worse in deep formations.Lateral seal ability of Surennuoer fault is good in the formations of D-1 segment and D-2 segment,which is worse or do not seal to the south of the seismic line I 340 of N-2 segment and is sealed in most of the rest parts of the segment.Surennuoer fault presents good lateral seal ability only in the parts between seismic line I 360 and I 420 and in the eastern parts of seismic line x848 of N-1 segment,whereas in other parts,the lateral seal ability is bad.Through the study,we could conclude that Surennuoer fault controls oil and gas accumulation in this region from two aspects: one is that the vertical distribution aviation of lateral seal ability of faults attribute to the variation of reservoir vertical distribution,and the other impact is that the horizontal distribution variation of lateral seal ability of faults results in the variation of reservoir distribution along the faults.
