摘　　要：针对油藏概念模型和实际模型存在的不足,提出了一个能够反映油藏主要地质特征、井网特征、生产特征、渗流特征和剩余油分布特征的新模型油藏特征模型,给出了建立油藏特征模型的详细思路和具体步骤。油藏特征模型建模相对简单,反映油藏地质特征和开发特征的程度介于概念模型和实际模型之间,但能够反映油藏的主要渗流特征和剩余油分布特征,在此基础上,可以开展油藏开发机理和具体的注水技术措施研究。同时,该油藏特征模型的建立也提供了一种新的建模思路,扩展了目前油藏模型的类型。最后,以孔二北油田为例详细介绍了建立油藏特征模型的具体过程,并提出了建立在此油藏特征模型基础上的优化周期注水技术措施。Considering the disadvantages of reservoir concept model and real model,a reservoir characteristic model is proposed which can reflect the main reservoir geological characteristics,well pattern characteristics,production characteristics,percolation characteristics and distribution characteristics of remaining oil. The steps of establishing reservoir characteristic model are described in details. Its modeling process is simpler,and the effectiveness which reflects the geological and development characteristics lies somewhere in between those of the concept and real models. However,the model is able to present the main percolation characteristics and distribution characteristics of remaining oil. Based on this new model,development mechanism and actual water injection strategies are studied. Meanwhile,reservoir characteristic model provides a new method of modeling and expands the types of reservoir model. At last,Kongerbei Oilfield is taken as an example to describe the details of establishing the reservoir characteristic model and the cyclic water flooding strategies are studied on the model.
