Zusammenfassung:The invention discloses a coiled tubing fine control fracturing potential tapping method after full well section temporary plugging. The problem that an existing vertical well coiled tubing fine control fracturing method cannot adapt to old well construction is mainly solved. The method is characterized in that clear water is used for ground flow circulation and pressure testing; a prepared temporary plugging agent with the particle size alpha being less than 2 millimeters and greater than 3 millimeters is fed into a pipeline from a wax ball manifold and pumped into a stratum through a pump truck; the prepared temporary plugging agent with the particle size alpha being less than 1 millimeter and greater than or equal to 2 millimeters is fed into the pipeline from the wax ball manifold and is pumped into the stratum by the pump truck; the prepared temporary plugging agent with the particle size alpha less than or equal to 1 millimeter is fed into the pipeline from the wax ball manifold and pumped into the stra
