The utility model relates to a direct-reading adjustable stratified water-flood device, which uses three independent water-flood passages to flood water in stratified layers, wherein each of the water-flood passages is composed of a packer Y341-114ML, an oil pipe 3', an oil pipe 11/2' and a sealing section. The ground uses a flow meter and a pressure gauge to monitor stratified flow quantity and stratified pressure, and to accurately adjust the water flood quantity and the pressure of each of the stratified layers in time. A test of underground flow quantity is not used, and the water quantity of the stratified layers is adjusted by the ground, which is direct in view, easy and accurate. The utility model can flood water simultaneously and respectively into the layers as well as can flood the water into each of the layers sequentially, which achieves the purpose of fine water flood. A pipe sealing check is simple and direct in view, a middle layer just needs to be flooded with the water and an upper and a lower layers are stopped from being flooded with the water. The pressures of the upper and the lower layers just need to be observed whether to change according to the water flood pressure of the middle layer from the ground. The technological principle is simple and strong in operability, and a large number of testing work is canceled. The technology has obvious effects on the aspects of saving operating cost, testing cost and increasing oil. The utility model has simple structure and reasonable design.
