摘　　要：鄂尔多斯盆地安边地区安83井区长7油藏储层属于典型的致密油藏,影响其产能因素很多,对该区进行产能预测有诸多困难。如何有效利用测井资料来评价致密储层的产能是亟待解决的问题。以测井资料为基础,利用影响每口井储层产能的关键因素(储层有效厚度、渗透率、孔隙度、含油饱和度、电阻率和泥质含量)为主要评价参数建立4种多参数组合产能系数预测模型,对该区进行产能预测,将该区致密储层分为低渗和超低渗储层两类。实践结果表明,该区进行产能预测应用取得较好的实用效果,达到利用测井资料预测该区致密储层产能和指导油田勘探开发目的。The Chang7 Formation of An83 Block of Anbian of the Ordos Basin area is typical of tight reservoirs. There are many difficulties which affect the capacity of this area to predict the capacity of tight reservoir. It is a severe problem which to effectively use logging data to evaluate the capacity of dense reservoir to be solved. In this paper,we has established four kinds of the combination of multi-parameter productivity index forecasting model on the basis of logging data,by which to predict productivity in Chang 7 Formation of An 83 Block of Anbian of the Ordos Basin area. The tight reservoir of this area was divided into two categories,namely,low permeability and low permeability reservoir. We achieved a good practical effect by using this method to apply for productivity prediction of the district and guided the purposes of the exploration and development of the oilfield.
