Classification of drilling methods. According to the nature of rock destruction, the drilling methods used are divided into: mechanical - the drilling tool directly affects the rock, destroying it, and non-mechanical - destruction occurs without direct contact with the rock from the source of impact on it (thermal, explosive, etc.). Mechanical drilling methods are divided into rotary and percussion-rope drilling (as well as rotary-impact and rotary impact). During rotary drilling, the rock is destroyed due to the rotation of the tool pressed to the bottom. Depending on the strength of the rock, a cutting type drilling tool is used during rotary drilling; diamond drilling tool; shot bits that destroy rock using shot. Impact drilling methods are divided into: impact drilling or impact-rotary drilling (drilling with rotary hammers, including submersible drills, percussion-rope, rod, etc., in which the rotation of the tool is carried out at the moment between impacts of the tool on the face); impact-rotational (with down -the- hole pneumatic and hydraulic hammers , as well as drilling with rotary hammers with independent rotation, etc.), in which blows are applied to a continuously rotating tool; rotational-impact , in which the rock-cutting drilling tool is under high axial pressure in constant contact with the rock and destroys it due to rotational movement along the face and periodically applied blows to it. Destruction of rocks at the bottom of a well is carried out over its entire area (solid bottom drilling) or along the annular space with core extraction (core drilling). Removal of destruction products can be periodic with the help of a bailer and continuous with augers, twisted rods or by supplying gas, liquid or solution to the face. Sometimes drilling is divided according to the type of drilling tool (auger, rod, diamond, roller, etc.); by type of drilling machine (perforator, pneumatic percussion , turbine, etc.), by method of drilling wells (inclined, cluster, etc.). Drilling equipment consists mainly of drilling machines (drilling rigs) and rock cutting tools. Among non-mechanical methods, thermal drilling has become widespread for drilling blast holes in quartz-containing rocks , and work is underway to introduce blast drilling.
Drilling has developed and specialized in relation to three main areas of technology: the deepest wells (several km) are drilled for oil and gas, shallower ones (hundreds of m) for prospecting and exploration of solid minerals, wells and boreholes with a depth of several m to tens of m are drilled for placement of explosive charges (mainly in mining and construction).
