Abstract

The acquisition relates to the field of oil production and m. used for well development and bottomhole formation treatment. The purpose of the invention is to produce non-inert gases with high pressures and temperatures. The device contains a cylinder with a piston (P) 1 placed in it, forming with the lower combustion chamber and connected to the connecting rod 2. The inlet and exhaust valves (K) are installed in the combustion chamber. The connecting rod 2 has an internal combustion engine and a crankshaft 10 and is connected by one condom with an eccentric pin 3 with P 1, and the other with a shaft 10. A spring-loaded) 1st reverse K is installed over the outlet K. The finger 3 has a rotation mechanism around the axis the form of the shaft 6 passed through the connecting rod 2, kinematically interconnected about

The invention relates to a technique for the extraction of oil and can be used for the development of wells and the processing of a bottomhole zone.

The purpose of the invention is the production and injection of high pressure and temperature inert gases into the oil well.

FIG. 1 shows a connecting rod-piston for a device in FIG. 2 shows an exhaust valve assembly; FIG. 3 - scheme of the device.

The device contains (Fig. 1) a piston 1 connected to the upper head of the connecting rod 2 by means of an eccentric pin 3, whose axis is displaced) relative to the axis of the support journals, to form an eccentricity. The top head of the connecting rod 2 is made in the form of a fork, in which on the pin 3 there is a sprocket 4j connected to another sprocket 5 mounted on the shaft 6 of the connecting rod. The sprocket 5 is placed in the through cavity at the bottom head of the connecting rod 2. The shaft 6 is mounted in the connecting rod 2 on bearings 7 perpendicular to the through cavity. A gear wheel 8 is mounted on the end part of the shaft 6, which engages with another gear wheel 9 mounted on the crankshaft connecting rod 10. The connecting rod 2 has longitudinal grooves for accommodating the chain drive chain. The gear ratio of the chain transmission is 1: 1, and the gear ratio is 1: 2. In the head 11 (Fig. 2) above the exhaust valve 12 is installed a check valve 13, spring-loaded spring 14.

The device works as follows (Fig. 3).

As piston 1 moves down, a fresh charge is delivered to the cylinder through the inlet channel (Fig. 3a). At this time

reverse K is open. When reaching the dead point, P 1 moves upwards and compresses the combustion products. Graduation and return to open. Combustion products are completely forced out of the cylinder P 1. 3 il.

exhaust 12 and check valve 13 are closed. When piston 1 moves upward, air is compressed, and when it reaches the top dead

points injected into the combustion chamber are fuel that is mixed with air and burned (Fig. 36). In this case, the axis of the finger 3 is located below the axis of its necks in the lowest position.

When piston 1 moves downwards after combustion of the combustible mixture, the inlet valve is closed and the inlet valve is open, but the check valve 13 is closed, since the outlet system has a high

pressure (Fig. 3 in).

After reaching the bottom dead. points piston 1 moves up. At this time (Fig. 3g), the inlet valve is closed, and the exhaust 12 and the reverse 13 are open, the tick, like a piston, compresses the products of the side of the fuel to a high pressure, exceeding the existing pressure in the exhaust system. Combustion products are completely displaced by the piston.

1 from the cylinder, because the upper dead point (in this case, is in the extreme upper position and there is no free space between the piston and the head). At this point, the axis

the finger 3 is located above the axis of its necks in the extreme upper position (FIG. 3 d).

Further, the operation cycles of the device are repeated. At the first movement.

The piston 1 upwards the device works as a diesel internal combustion engine with a height of the combustion chamber in the cylinder equal to the sum of two eccentricities of the finger 3, and during the second

upward movement of the piston 1 works as a compressor (supercharger) with a height of the combustion chamber equal to zero.

The operation of the device is provided by the rotation mechanism of the eccentric pin 3. When the crankshaft 10 and the wheel 9 rotate, the wheel 8 makes a half-turn. The sprocket 5 makes the same number of revolutions. Thus, for two turns of the crankshaft 10, the wheel 8 and the sprocket 5 make one revolution. Synchronously with wheel 5, another sprocket 4 rotates because the gear ratio of the chain transmission is 1: 1.

Consequently, during the first ascent, the piston 1 does not reach the head for a distance equal to two eccentricities of the finger 3, and with the second ascent it reaches the head.
