俄罗斯研制出一种强化开采低渗透储层的化学负压综合处理工艺。主要程序是 :依次往产层注入化学剂 ,延缓反应 ,在负压条件抽汲出已反应的化学剂。实验表明 ,该方法可以成倍地增加原油产量 ,降低含水率 ,是一种强化开采低渗透储层很有前途的方法 Russia developed a chemical extraction of low-permeability reservoir exploitation comprehensive treatment technology. The main program is: sequentially injected into the formation of chemicals, delaying the reaction, under negative pressure pump out the chemical reaction has been. Experiments show that this method can double the crude oil production and reduce the water cut, which is a promising method to enhance the exploitation of low permeability reservoirs
