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。
隨著勘探難度加大、新增儲量品位下降，低滲透儲量所佔的比例將越來越大，開髮難度也將進一步加大，開髮矛盾越來越突齣。用常規的孔隙度、滲透率、產能的高低已難以評價低滲透油藏的開髮潛力和開髮難度。採用微觀孔隙結構、可動流體百分數、啟動壓力梯度等參數，可有效分析低滲儲層的滲流特徵，評價其開髮潛力，為油田有效註水開髮、增儲上產提供可靠的科學依據。

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.
