The technical effects of the utility model are that: the logging mode is changed from fixed injection allocation amount to adjustable injection allocation, the traditional water distributor and the blanking plug are integrated, the blanking plug is replaced by an adjustable device, the size of the water nozzle is large, the cross-sectional area of water is increased from phi 8 to phi 18, and the water injection amount is increased by more than 5 times. By the cooperation of the intelligent testing and adjusting instrument, testing and adjusting can be realized on the ground, and the testing rate and the accuracy are greatly improved. The structural change thoroughly eradicates the sand burying phenomenon of the traditional blanking plug. The structural change improves the strength of the water distributor part, and the service life is prolonged by more than 4 times. The novel water distributor adopts a concentric structure, and the length dimension of the novel water distributor is 290mm smaller than that of the original water distributor, so that the novel water distributor can better adapt to well conditions, and is particularly suitable for large inclined wells.
