3.2. Drilling with the expansion of wells through the installation of horizontal drilling
The essence of the method consists in using special drilling rigs (drilling, rods), which carry out a preliminary (pilot) drilling on a pre-calculated trajectory followed by the expansion of wells (with a set of extenders) and the dragging of a cavity of the PEX pipe. Fig. 3.2.1 shows a diagram of the expansion of drilling wells through the installation of horizontal drilling.
