Replacement of balloon-type autonomous settings used for water flooding by autonomous hydro - gas pipe accumulators for a working pressure of up to 40 MPa.

The production of pipe hydro - gas pipe accumulators like autorider which replaces one on the basis of balloon-type autonomous with compressed natural gas is mastered to date.

Advantages:
Pipe HGA have improved features for constructive strength and security in comparison with gas cylinder;
It does not need a new production of cylinders, because production has already existed and fitted with equipment and certified test benches for and hydraulic and air/hydraulic test facilities of PHGA.

Semi-automatic device of displacement tool for selective pump-down into wells (TSPW)

Reversing valve moves from one extreme to another in accordance with of remotely supplied command with multiple work (response in 10-15 during operation) through the use of energy effects of structural materials with shape memory when the temperature changes.
At manufacturing power element, for example, springs from material that has shape memory, such as nickel-titanium alloy (titanium nickelide) can reach the reversibility deformation at 100% degree of recovery both in the form of single or multiple forms of rebuilding (up to 1 million cycles) . In this case, spring-loaded device located in a limited area could provide many times invertible movement of the reversing valve belongs to TSPW in a thermal cycling.

Advantages:
Nickel-titanium alloy has high efficiency of impact energy per the mass unit and exceeds efficiency of mechanical, electromagnetic anchorages in a specific energy;
Corrosion resistant alloy in severe environments and thermal cycling is very assumptive suitable for TSPW.

Crown tool of the extra-hard material with leak-free electric drives for the formation of by-lane drifts through radial holes of TSPW.

When using crown tool from extra-hard material in rocks the driving of small-diameter drift (up to 19 mm) is fulfilling via drilling with bore-bit done from ultra-hard “Skeleton-D” material at a speed over 4 m/sec.
The potation is provided by double electro motors of unilateral type via flexural or telescopic shafts, simultaneously, in 2 radially opposite directions.

Advantages:
Durability increasing of gear system in 10 times;
Independent ensuring a smooth and discrete regulation of the speed, while maintaining the force moment keeping on the shaft;
Leak-proof-ness ensuring and work in any environment without expensive special protection measures.
