摘　　要：吉林油田低渗透储层注采关系建立难度大,采收率较低,且不同区块开发效果存在较大差异。分类参数、界限不统一,储层分类评价无法进行。总结吉林油田低渗透油藏宏观、微观储层特征,结合典型区块动态开发效果影响因素,先初选分类参数,再利用灰色关联法确定最终分类参数。引用概率累积法,计算各定量参数的分类界限,同时借鉴Feci综合指数法,对储层进行综合分类评价,建立了吉林油田扶余、高台子油层的综合分类标准。利用储层分类的标准,对各油田扶余及高台子油层的146个开发单元进行了归类,总结出制约低渗透各类储层开发的主要矛盾和问题,明确了提高采收率的攻关方向,为各类储层制定主导开发技术政策奠定了基础。It is difficult to establish the injection-production relationship of low permeability reservoir in Jilin Oilfield.As a result,the recovery rate is low,and the development effect of different blocks is different.In addition,the classification parameters and boundaries are not unified,so the reservoir classification and evaluation cannot be carried out.This paper summarizes the macro and micro reservoir characteristics of low permeability reservoirs in Jilin Oilfield,and combines the influencing factors of dynamic development effect of typical blocks.The classification parameters are selected first,and then the final classification parameters are determined by grey correlation method.In addition,the probability accumulation method is used to calculate the classification limit of each quantitative parameter,and the Feci comprehensive index method is used for comprehensive classification and evaluation of reservoirs,and the comprehensive classification standards of Fuyu and Gaotaizi reservoirs in Jilin Oilfield are established.Finally,146 development units of Fuyu and Gaotaizi reservoirs in Jilin Oilfield are classified according to the reservoir classification standard,and the main contradictions and problems restricting the development of various low permeability reservoirs are summarized.The research direction of EOR is clarified,which lays the foundation for the formulation of leading development technology policy for various reservoirs.
