本文以辽河西部凹陷沙三段为例,针对重力流沉积体系中油气储层和隔、夹层的时空展布特征,采用地质统计学中的条件随机模拟方法预测了隔夹层在空间上的展布,并且进一步应用分形几何学方法识别出3种不同类型的隔夹层.

Taking Sha-3 member of western Liaohe depression as an example,on the basis of characteristics of time and spatial distributions for the reservoirs,insulating and interbeds in the turbidite sedimentary system,the conditional stochastic simulation method of geostatistics is applied to predict the space distribution of insulating and interbeds.Furthermore,three different types of interbeds are identified with the application of fractals.
