This invention relates to the field of oil and gas field fracturing technology, and particularly to an integrated device and method for horizontal well cluster-level fluid extraction, production measurement, and fracturing. The technical solution is as follows: a multi-nozzle pressure-controlled switch jet pump and a first packer are connected to the casing downhole via tubing. Within the horizontal section, a production measurement and fracturing control valve and a water hammer wave monitor are connected via tubing. The production measurement and fracturing control valve and the water hammer wave monitor are located between the second and third packers. The advantages are: by coordinating the multi-nozzle pressure-controlled switch jet pump with the production measurement pump core of the storage-type downhole jet pump, fluid extraction and formation production data can be measured in cluster-level sections of the horizontal well. Furthermore, by moving the positions of the production measurement and fracturing control valve and the water hammer wave monitor, fracturing operations can be performed on the corresponding cluster sections requiring modification. Simultaneously, water hammer wave data can be measured at close range. A single drilling run completes the functions of fluid extraction, production measurement, and fracturing, resulting in low construction costs and high measurement accuracy.
