A construction method of an anchor pile structure suitable for a foundation with at least a shallow portion under the earth surface being loose sand, the anchor pile structure comprising a hollow precast pile body (12), an anchor body structure (29) having a container (6) and an anchor rod (26), the method comprising the following steps: 1) in the foundation, arranging the precast pile body (12) in a prescribed position in the foundation; (2) a hole (28) is formed downwards through the interior of the cavity of the pile body (12), the hole forms an installation space of an anchor body structure (29), and at the moment, the hole is filled with slurry; the method comprises the following steps of (1) placing a container (6) in a cavity of a precast pile body (12), (2) placing the container (6) in the cavity of the precast pile body (12), (3) downwards penetrating an anchor body structure through the cavity of the precast pile body (12) and placing the anchor body structure in a hole, (4) pouring cement paste into the hole (28) to replace the slurry in the hole, (5) after the cement paste in the hole is hardened, filling a medium into the hollow interior of the container (6) and carrying out squeezing expansion to enable the container (6) to laterally expand, and (6) grouting a soil body near the bottom end of an anchor rod (26).

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.
