Beschreibung
Zusammenfassung:	The invention provides a well completion testing tool which comprises an outer cylinder, and an upper circulating hole and a lower circulating hole are formed in the outer cylinder; the inner cylinder is arranged in the outer cylinder, the inner cylinder and the outer cylinder are detachably connected, and the inner cylinder and the outer cylinder can relatively slide in the axial direction after being separated; wherein during circulating acid replacement operation, the inner cylinder is in a first state, at the moment, the inner cylinder blocks the upper circulating hole, and the lower circulating hole is in an open state; during transformation operation, the inner cylinder moves to a second state in the axial direction, and at the moment, the inner cylinder blocks the upper circulating hole and the lower circulating hole; and during well killing and leaking stoppage operation, the inner cylinder moves to a third state in the axial direction, and at the moment, the upper circulating hole and the lower circu
