摘要
以３个地区低渗透储层的地层水与不同碱溶液系列配备实验为基础，结合动、静态储层伤害评价，探讨钻井液滤液对储层的伤害机理，并提出保护储层的钻井液技术要求，建议结合岩心流动实验，综合评价各类外来流体对储层的伤害程度，从中筛选配伍性良好的入井液处理剂。
Based on series compatibility test of formation water of 3 low permeable reserviors with all kinds of alkaline solution, combined with reservior injury assessment by the way of static and dynamic states, this paper analysed injury mechanism of well drillong liquid to reserviors and suggested some requirements of well drilling liquid for protecting reserviors. It was suggested that injury extent of all kinds of external fluid to reserviors should be comprehensively evaluated at the same time of doing core flowing test, then the treatment reagent for well liquid with better compatibility can be selected.
