Method for increasing recovery ratio of tight oil reservoir through CO2 foam huff and puff

The invention relates to a method for increasing the recovery ratio of a tight oil reservoir through CO2 foam huff and puff. The method comprises the steps that high-pressure CO2 is injected into the fractured tight oil reservoir for slugging, cracks are mainly filled with CO2 for soaking, and crude oil enters the cracks from the matrix under the actions such as extraction, volume expansion and dissolution and viscosity reduction; and after the pressure of a wellhead is stable, a well is opened for production, in the formation seepage process, CO2 makes contact with a surface active agent aqueous solution to generate foam, the CO2 foam displaces the crude oil so that the crude oil can flow from the cracks to a shaft, and finally the crude oil is recovered to the ground. According to the method, no foam is generated in the CO2 injection process, and the situation that the generated CO2 foam displaces the crude oil to the deep position of the oil reservoir is prevented; and in the recovery process, the CO2 makes contact with the surface active agent aqueous solution so that the foam can be generated in the stratum, through the mechanisms that the CO2 foam conducts oil cleaning in the cracks and the fluidity of CO2 is effectively controlled, more crude oil in the cracks can be displaced into the shaft, and the recovery ratio of the tight oil reservoir is increased.
