摘要
Abstract
Air foam flooding and CO2 flooding are important technical means for tertiary oil recovery in low permeability oil fields.In order to study the suction of injection zones,injection profile logging evaluation is needed.However,the unstable system characteristics of air foam fluid and the supercritical state character-istics of CO2 are different from those of conventional water drive fluids,and the applicability of conventional logging methods needs to be evaluated and studied.On the basis of studying the principle applicability of the existing injection profile logging methods,it is found that the eight-parameter injection profile logging method has good adaptability in CO2 and cavitation flooding,pulsed neutron oxygen activation can be used in CO2 injection profile logging,conventional isotope tracer logging method has poor adaptability in cavitati-on and CO2 flooding,and distributed fiber logging method has strong adaptability.It has a good application prospect in CO2 and cavitation flooding.关键词
