摘要(Abstract)：

目前勘探阶段常用的克立格估计储层预测方法的特点是平滑内插 ,不能精细地描述局部小范围特征。而随机模拟能够反映储层分布的细节 ,有助于精细描述储层的非均质性 ,且能给出一定范围内的多个可选储层模型 ,从而提高预测的可靠性。因此 ,应用三维随机顺序指示模拟方法在松辽盆地北部齐家 古龙凹陷英 31井区对黑帝庙油层砂岩分布进行了模拟 ,模拟结果客观地反映了黑帝庙油层砂岩分布规律。利用随机指示模拟结果 ,识别黑帝庙油层岩性圈闭 12个 ,面积 134 38km2 ,表明随机建模可以对储层分布进行高分辨率描述 ,是薄互层储层和复杂岩性储层预测、描述的有效手段
The Kriging based reservoir prediction methods that presently have been in common use at oil/gas exploration phase have a characteristic of interpolation with smoothness.These methods can only reveal the region figure of a reservoir,and can not describe its details.Stochastic simulation can not only reveals the details of reservoir distribution but also gives several reservoir model to choice to a certain range.Using Stochastic simulation technique,we can precisely describe the heterogeneity of reservoir and analyse the uncertainty of reservoir predicting, then the reliability of reservoir predicting should be improved. In this paper,a case of sequential indicator simulation has been presented.3D sequential indicator simulation has been used to Heidimiao formation of Ying31 well block,Qijia Gulong depression,north part of Songliao basin.The simulation result accords with the deposit feature of Heidimiao formation.Using the result of 3D sequential indicator simulation,we have discovered 12 lithological traps with total area of 134 38 km 2. Stochastic simulation technique can be used to describe reservoir distribution with high resolution,so this technique should be an effective way for reservoir description of thin interbedded and complex lithological formation.
