Petroleum drilling screen tube
The positioning of the drilling rig for drilling screen tubes is accurate, horizontal, and stable. After the drilling rig is positioned, the upper mouth of the casing is hung on the drilling frame chassis with a steel wire rope. During the drilling process, the pulley group at the head of the drilling rig tower and the drill bit are always kept on the same vertical line, ensuring that the drill bit is drilled in a tightly suspended state. The diameter of the borehole must reach the design pile diameter.

Select mud that is suitable for geological conditions during the drilling construction of the drilling pipe. Pores are formed in sandy soil and thicker sand layers, with a mud specific gravity controlled between 1.1 and 1.3. When drilling in soil layers prone to collapse, the mud specific gravity is controlled between 1.3 and 1.5. During construction, the mud specific gravity is often measured, and its viscosity, sand content, and colloid content are measured. Adjustments are made according to different soil layers.
