Description

A device and application method for directional drilling

technical field

The invention belongs to the technical field of drilling, and in particular relates to a device and an application method for directional drilling.

Background technique

Drilling is the operation of using a drill to create a hole in a solid material. The drilling work in the exploration work is described here, as well as the auxiliary tools required for drilling and some emergency measures. In geological exploration work, a cylindrical hole with a smaller diameter and a larger depth is drilled into the ground by drilling equipment, also known as drilling. Drilling holes for oil and gas and groundwater are larger in diameter. The diameter and depth of the borehole depend on the depth of burial of geological minerals and the purpose of the borehole.

The names of the drilled parts are shown in the figure. The starting part of the drilling is called the hole, the side is called the wall of the hole, and the bottom is called the bottom of the hole. The diameter D of the drilled hole is referred to as the diameter of the hole, the diameter of the orifice is called the diameter of the opening, and the diameter of the bottom of the hole is called the diameter of the final hole. The distance H from the orifice to the bottom of the hole is called the drilling depth, abbreviated as the hole depth. A section of a drilled hole is called a hole section.
