摘　　要：以辽河油区东部凹陷龙10断块沙一段为例,利用波阻抗与沉积微相之间的概率关系及开发动态中的各沉积微相参数(宽度、厚度、体积含量),以沉积模式为指导,应用序贯指示同位协同模拟方法,建立储层沉积微相相模型。实践表明,该方法能够对相变复杂的陆相储层井间沉积微相不确定性进行表征,提高模型预测的可靠性。A model of reservoir sedimentary micro-facies is established with S1 in Block Long10,eastern depression,Liaohe Oilfield,as an example,by using the probabilistic relationship between wave impedance and sedimentary micro-facies as well as parameters(width,thickness and volume) of the micro-facies in development performance,guiding by depositional model,and applying sequential coordinate modeling.Practice shows that this method is capable of characterizing the uncertainty of interwell sedimentary micro-facies of continental reservoirs with complex facies change to improve the credibility of model prediction.
