9. A wellbore pipe arrangement method for piping a wellbore using the wellbore pipe arrangement device according to any one of claims 1-8, comprising the steps of:
s1, enabling the pipeline to penetrate through the pipeline through hole of the fixed disc and fixedly connecting the pipeline through hole through a fixing element to obtain an assembled pipeline fixing unit;
s2, according to the height of the shaft, the pipes of the assembled pipe fixing units needed by the determined number of shafts are aligned and welded according to a four-point limiting method, and a preliminary shaft pipe arrangement device is obtained;
s3, fixing a guiding device on a fixed disc at the lowest end of the preliminary shaft pipeline arrangement device; the guiding device comprises a cone structure arranged at the bottom of the fixed disc, and the shape and the area of the bottom surface of the cone structure are the same as those of the bottom of the fixed disc, so that the standby shaft pipeline arrangement device is obtained;
s4, lowering a standby shaft pipeline arrangement device required by a shaft into the shaft from a cylinder mouth of the shaft through a hoisting device until the pipeline reaches the preset height of the shaft, and obtaining a primary pipeline arrangement shaft;
s5, pouring concrete slurry into the primary pipeline arrangement shaft from the upper port of the primary pipeline arrangement shaft, and plugging the lower port of the primary pipeline arrangement shaft through an annular plugging disc pre-arranged at the top of a connecting passage of the shaft to prevent the concrete slurry inside the shaft from flowing outwards so as to obtain the backfilled and poured pipeline arrangement shaft;
and S6, maintaining the pipeline arrangement shaft after backfilling and pouring, and finishing the pipeline arrangement of the shaft after the concrete slurry in the shaft reaches the preset strength.
10. The wellbore tubing arrangement method of claim 9, further comprising, before lowering a wellbore required standby wellbore tubing arrangement device from a wellhead of the wellbore to an inside of the wellbore through a hoisting device until the tubing reaches a preset height of the wellbore, obtaining a preliminary tubing arrangement wellbore:
carrying out shaft construction by adopting a drilling machine to obtain a shaft;
and hanging a test ball body into the shaft through a thin steel wire rope, and testing the diameter of the shaft.
