摘要(Abstract)：
台105合作开发区葡萄花油层属低渗透-特低渗透岩性油藏。油层厚度小,空气渗透率低,储油物性差,钻井及注水开发时,极易受到伤害。为有针对性地采取油层保护措施,对合作开发区岩石样品进行了"五敏"实验,并采取了一系列油层保护措施。首先优选入井流体,然后在钻井、完井、注水及采油过程中应用相应的油层保护技术,收到了明显效果,最大限度地减轻了油层污染,提高了采出程度。
Tai 105 cooperative developing block is a lithologic reservoir of low or extra low permeability.Reservoir thickness is small,air permeability is low,reservoir physical property is poor.It is susceptible to damage so that permeability may be further low and production may be reduced or lose completely.We have conducted "five susceptivity"testing in order to protect oil reservoir and enhance oil recovery.The final result indicates that most samples are sensitive moderately or less moderately,and the higher permeability of oil reservoir is,the slighter damage level is;the more serious damage level is,the lower permeability of oil reservoir is.We have applied a series of reservoir protection measures on the base of low or extra low permeability characteristics.First,we have selected entry well fluids,secondly,we have used many advanced reservoir protection techniques during the stages of well drilling,completion perforation and water injection development, and gained distinct effect.Reservoir damage level has been reduced mostly and oil production per thickness has been enhanced.
