摘　　要：通过物理模拟实验研究了介质变形对低品位油藏物性的影响,结果发现:介质变形产生的压敏效应对低渗透油藏的渗透率、产能影响比较大,而这一点却往往被很多油田开发工作者忽略。运用油藏工程方法进行理论推导,量化了压敏效应对渗透率和产能的影响,并提出了一种考虑压敏效应计算合理注水时机的方法,编制了相应的软件,对江苏油田某区块进行了实际应用,得到了较好的效果。研究表明,介质变形造成的渗透率损失和产能的降低对低品位油藏开发的影响应引起足够的重视,要特别注意注水时机,保持合理的地层压力,尽量减少其对开发的不利影响,改善开发效果。The effect of media deformation on lean reservoir physical property is studied by means of physical simulation experiment.And the result indicates that the influence of pressure sensitivity on permeability and deliverability is great,but it is always neglected by many oilfield development workers.Then,the influence of pressure sensitivity on permeability and deliverability is quantified with reservoir engineering method,one of the methods is proposed to calculate reasonable water-flood timing,and corresponding software is developed.It is practically applied in Jiangsu oilfield and the effectiveness is very well.The research demonstrates that the effect of medium deformation on lean reservoir development should be brought to high attention.It should be cared to choose right water-flood timing and maintain reasonable formational pressure to decrease harmful impact and improve development effects.
