摘要
由于低渗储层孔喉细小,渗透率低,物性差的特点,为了达到较好的开发效果,往往需要对储层进行改造。目前主要以水力压裂方式为主。但采用水力压裂在改造储层的时候,压裂液也对储层造成一定的伤害。本文对低渗储层水基压裂液伤害的因素进行分析。结果显示,水基压裂液对低渗储层伤害的主要方式为水锁伤害、水敏伤害、残渣造成的伤害、不配伍造成的伤害、吸附滞留伤害、乳化伤害。
Due to low permeability reservoir pore throat tiny,low permeability,poor physical characteristics,in order to achieve better effect,the reservoir often need to be transformed.Currently,the main way to the main hydraulic fracturing.But the use of hydraulic fracturing in the transformation of the reservoir when the reservoir fracturing fluid can cause some damage.Therefore,low permeability reservoirs in water-based fracturing fluid injury factors were analyzed.The results showed that the main form of water-based fracturing fluid for low permeability reservoir damage,water locking damage,water sensitivity damage,damage caused by residues,incompatible damage caused by adsorption retention hurt,emulsifying injury.
