摘　　要：CO_(2)受温度和压力的变化影响,会形成不同的相态,CO_(2)气溶性发泡剂在不同的CO_(2)相态中表现出不同的发泡特点。本文研究了无水、煤油、有机溶剂以及低水条件下CO_(2)气溶性发泡剂在液态、超临界以及气态CO_(2)中的发泡性能,研究表明在低水(含水量<5%)条件下CO_(2)气溶性发泡剂可以在超临界CO_(2)中有效发泡。利用该CO_(2)气溶性发泡剂,可实现低水油藏的有效开发。Under the influence of temperature and pressure,CO_(2)would form different phase states,and CO_(2)gas-soluble foaming agent showed different foaming characteristics in different CO_(2)phases state.In this paper,the foaming properties of CO_(2)gas-soluble foaming agent in liquid,supercritical and gaseous CO_(2)under the conditions of anhydrous,kerosene,organic solvent and low water were studied.Results showed that CO_(2)gas-soluble foaming agent could effectively foam in supercritical CO_(2)under the conditions of low water(water con-tent<5%).The CO_(2)gas soluble foaming agent could be used to effectively develop low water reservoirs.
