摘要:
针对目前特低渗、超低渗透致密砂岩储层物性差、有效动用难度大等问题,综合使用恒速压汞、核磁共振、离心实验及油水驱替等实验技术对储层微观孔隙结构、可动流体百分数、非达西渗流特征等进行了系统研究。研究结果表明特低渗、超低渗致密砂岩储层微孔隙的喉道半径、可动流体百分数、启动压力梯度是判断该类储层渗流能力大小的关键指标。以这3个参数作为评价指标,利用模糊数学评判对目前江苏油田已发现未动用的特低渗、超低渗透储量进行综合评价。评价结果显示这部分储量有开发动用的潜力。
Abstract:
Aiming at the poor physical property and difficulties in effective development of tight sandstone reservoirs with extra-low or super-low permeability,based on rate-controlled mercury penetration,NMR,centrifuge experiment and oil-water displacement experiments,systematic studies were conducted in aspects of the reservoir microscopic pore structure,mobile fluid percentage and non-Darcy flow feature.Results showed that throat radius of microscopic pores,mobile fluid percentage and starting pressure gradient are the key indexes to decide the flow ability in extra-low or super-low permeability tight sandstone reservoirs.Taken these three parameters as evaluation indexes,comprehensive evaluation through fuzzy mathematics judgment was conducted in unproducing reservoirs that have already been found.The evaluation results indicated that there was the potential of developing and employing in these reservoirs.
