摘　　要：随着勘探难度加大、新增储量品位下降,低渗透储量所占的比例将越来越大,开发难度也将进一步加大,开发矛盾越来越突出。用常规的孔隙度、渗透率、产能的高低已难以评价低渗透油藏的开发潜力和开发难度。采用微观孔隙结构、可动流体百分数、启动压力梯度等参数,可有效分析低渗储层的渗流特征,评价其开发潜力,为油田有效注水开发、增储上产提供可靠的科学依据。With increased difficulties of exploration and additional reserves grade decline, the proportion of low permeability re- serves will increase. As a result, development difficulties will be increase and development contradictions will protrude. Conven- tional parameters, including porosity, permeability and deliverability, can hardly evaluate the development potential and difficul- ties of low permeability reservoir. However, the application of the parameters including micro-pore structure, movable fluids pro- portion and threshold pressure gradient can help effectively analyze the seepage characteristics of low-permeability reservoir and evaluate development potential. The results can provide reliable scientific basis for water-flood development and the increase re- serve and output.
