在油气储层损害机理当中除水敏损害,速敏损害等损害机理外,液阻效应(贾敏效应)对于低渗、特低渗储层来说,也是主要的损害机理之一,通过分析油气田生产过程中液阻效应的损害机理,转化不利因素为有利条件,在钻井过程中,在钻井液中加入油溶性暂堵剂应用液阻效应来有效的保护储层,取得了好的效果。 In addition to water damage damage, speed sensitive damage and other damage mechanisms, the liquid resistance effect (Jia Min effect) is also one of the major damage mechanisms for the low permeability and ultra-low permeability reservoirs. By analyzing In the process of oil and gas field production, the damage mechanism of liquid resistance effect and unfavorable conversion factors are favorable conditions. During the drilling process, the oil-resistant temporary blocking agent is added to the drilling fluid to effectively protect the reservoir by using the liquid resistance effect, and the good effect is achieved.
