摘要
液锁损害是低渗透储层最常见、最基本的损害因素之一,其损害程度主要与岩心渗透率、孔隙度、初始水饱和度及外来流体侵入后的油水界面张力等因素有关。基于塔里木油田低渗透岩心液锁损害的室内试验数据,建立了预测液锁损害的灰关联分析方法,并研制出快速智能化预测软件,预测符合率可达到95%以上,在智能化、快速化及预测符合率等方面具有明显的优越性,是目前较为理想的一种预测储层液锁损害问题的方法。
Fluid locking damage was one of the most essential damage factors in low permeability reservoirs,the level of damage was mainly related with core permeability,porosity,initial water saturation and oil-water interfacial tension of foreign fluid invasion.Based on the laboratory experimental results of water-locking damage of low permeability cores from Tarim Oilfield.The method of grey association analysis is established for predicting the fluid locking damage,and a rapid intelligent software is developed with predicting consistent ratio being over 95%.It has obvious advantage in intelligence,speediness and accuracy.It is an ideal method of predicting fluid locking damage.
