中文摘要:
      靖安油田杨66区延9储层主要为低-中孔、低渗-特低渗储层,其渗流条件相对较差。为了查明储层敏感性对渗流条件的影响,本文利用敏感性实验分析方法对区内延9储层的速敏、水敏、盐敏、酸敏和碱敏特征进行了分析。结果表明,研究区延9储层敏感性总体表现为中等偏弱速敏和水敏、弱盐敏、中等偏强酸敏、弱碱敏-改善,由于储层酸敏性较强,勘探开发过程中要注意低pH值溶液对储层的伤害,同时,在注水开发过程中,应确保注入水矿化度高于临界矿化度,这样才能更好地保护储层不受损害。
英文摘要:
      Yan 9 reservoir in Yang 66 area of Jing’an oilfield is mainly low medium porosity and low permeability extra low permeability reservoir, and its seepage condition is relatively poor. In order to find out the influence of reservoir sensitivity on seepage conditions, this paper analyzes the characteristics of velocity sensitivity, water sensitivity, salt sensitivity, acid sensitivity and alkali sensitivity of Yan 9 reservoir in this area by using sensitivity experimental analysis method. The results show that the sensitivity of yan9 reservoir in the study area is generally characterized by medium to weak velocity sensitivity and water sensitivity, weak salt sensitivity, medium to strong acid sensitivity and weak alkali sensitivity to improve. Due to the strong acid sensitivity of the reservoir, attention should be paid to the damage of low pH value solution to the reservoir in the process of exploration and development. At the same time, in the process of waterflood development, it should be ensured that the salinity of injected water is higher than the critical salinity, so as to better protect the reservoir from damage.
