摘要: 根据低渗透储层特点,利用恒速压汞、核磁共振、低渗透渗流理论和物理模拟实验研究手段,将喉道半径、可动流体百分数、启动压力梯度、有效驱动因子4个参数作为低渗透油储量的评价指标,建立了与之对应的分级评价方法和分级界限.同时以丰度、有效厚度、喉道半径、可动流体比率、启动压力梯度和有效驱动因子6个参数作为低渗透油田储量综合评价指标建立了评价新方法.该方法成功地应用于大庆油田外围低渗透储层评价,为低渗透储层的合理开发提供了理论依据.

Abstract: The rate-controlled mercury injection,nuclear magnetic resonance,porous flow theory of low-permeability reservoir and physical simulation were used to evaluate the reserves of low-permeability reservoirs,taking throat radius,percentage of mobile fluid,start-up pressure gradient and effective drive factor as the evaluating indexes.The corresponding hierarchical appraisal method and hierarchical demarcation line were set up.A comprehensive method for evaluating the reserves of low-permeability reservoirs was proposed.For the new method,reservoir's abundance,effective thickness and throat radius,as well as the percentage of mobile fluid,start-up pressure gradient and effective drive factor are taken as the evaluating index.This method has been successfully applied to the evaluation of low-permeability reservoirs in Daqing peripheral oilfield.

Key words: low-permeability oilfield, reservoir evaluation, evaluating parameter, comprehensive evaluation method, Daqing Oilfield
