Description

Description of the invention

The invention relates to the field of drilling technology. The electric drill is intended for drilling water wells and installing 2 tube wells.

Well-known drilling rigs have a mechanical drill, a power plant, a cutting tool, and casing (1, 2). They are characterized by a number of disadvantages: low productivity, bulkiness, high cost of production and maintenance.

To eliminate the noted shortcomings, an electric drill is used instead of a mechanical drill. 70 The invention "Electrobur" is based on the task of ensuring the creation of a highly efficient drilling rig (electric drill) by combining a deep water pump with a mechanical drill.

In fig. an electric drill is shown, where it is indicated: 1 - guide drill; 2 - cutter; C - submersible pump; 4 - supply pipe; 5 - casing pipe; 6 - capacity of water-soil mixture; 7 - power source; 8 - incoming water pipeline; 9 - capacity of clean water. 12 The electric drill has a deep water pump Z on one axis with which a milling cutter-like cutting tool 2 with a guide drill 1 is fixed. The milling cutters self-open and self-close when the electric drill passes through the casing pipes 5, which allows replacing the cutting blades of the milling cutter 2 or sharpening them.

Electric drill works as follows. From the tank 9 installed on the surface, clean water is supplied to the well through the incoming water pipeline 8, which, together with the cutter, crushes, dissolves and mixes the thin soil section with each rotation of the cutter 2. The water-soil mixture obtained in this way is used by a submersible pump

C is supplied to the surface in the capacity of the water-soil mixture 6, where the mixture settles. The resulting purified water is collected in a clean container 9, from which it is then fed into the well through the casing pipe 5 under its own weight, while filling the milling area of the soil, mixes with it and is pushed into the water-soil mixture container 6. The electric drill works from an electric source 7, located on the surface. 29 To prevent reversal, the electric drill is rigidly fastened to the supply pipe 4, which is extended as needed with the help of flange connections. The casing pipes 5 are lowered one by one immediately after the start of drilling. The inner diameter of the casing pipes should not prevent the lifting of the electric drill together with the milling cutter. The outer diameter allows free lowering of the casing pipes to the entire planned depth of the well.
