| description | The invention relates to the technical field of oil and gas field development, in particular to a CO2 flooding and channeling sealing system and a gas channeling regulation and control method thereof.The CO2 flooding and channeling sealing system comprises an oil-soluble surfactant and supercritical CO2, the volume ratio of the oil-soluble surfactant to the supercritical CO2 is 1: 1000-50: 1000 at the temperature of 60-80 DEG C and the pressure of 30-35 MPa, and the CO2 flooding and channeling sealing system has the advantages that injection is convenient, water-sensitive damage and corrosion are reduced, and the oil flooding effect is good.
本发明涉及油气田开发技术领域，具体涉及一种CO2驱封窜体系及其调控气窜的方法，所述CO2驱封窜体系，包括油溶性表面活性剂和超临界CO2，在温度60-80℃及压力30-35MPa下，两者体积比为1:1000-50:1000，具有方便注入、降低水敏伤害和腐蚀、驱油效果好的优点。 |
