Operation of wells by periodic gas lift method (1972)

Oil field, in the frame there is a field, oil and gas rigs are standing, pumps are working.

Close-up - the work of the pump mechanisms at the rig is shown.

In the frame - a sucker rod deep-well pumping unit.

An accident at the well - a broken pump mechanism is in the frame.

Close-up - the dial of the device, the arrow is at zero.

A worker approaches the rig, checks the units of the pumping unit and the deep-well pump.

Close-up - a part of the pump in the hands of a worker.

A repair crew at the well, in the frame there is tracked special equipment, a man in the cabin moves the levers.

General plan - the work of wells, pumping units is shown, workers are in the frame.

Close-up - a cable is unwound from a reel on special equipment.

A worker in a helmet supervises the process.

Panorama of the rigs, below, workers are performing repair work.

Drawing - an automatic hydropacker piston.

The work of such an installation is shown.

The installation is a well with a sealed annular space, into which a uniform column of lifting pipes is lowered.

The frame shows the unwinding of the cable, the man in the cabin moving the levers.

The bottom of the column is equipped with a tailpiece and a spring shock absorber.

The frame shows oil workers in helmets with pipe parts (assembling the rig).

A rig with a hydropacker automatic piston - it is shown how the structure is assembled.

Oil workers assemble the rig, prepare the drill for work.

The operation of the rig is shown.

Close-up - the upper spring shock absorber and piston catcher.

It is shown how the parts are mounted on a single-string reinforcement.

Close-up - the part is inserted into the piston.

The assembly process of the rig is shown (a worker is standing at the top, assembling the structure, another worker feeds him parts, etc.).

The automation system is mounted - a cycle regulator, which is designed to supply gas to the membrane-testing mechanism of the discharge valve.

Annular gas is used to power the cycle regulators.

A self-recording pressure gauge is also located in the power supply cabinet, recording changes in the annular and buffer pressure.

A man opens a cabinet, checks the instruments, tightens something and closes the cabinet.

Animation insert - liquid accumulation occurs in the lift pipes and partially in the annular space, a piston from the wellhead falls inside the column of lift pipes, plunges into the liquid, reaches the shock absorber and cuts off the liquid column.

The increase in gas pressure in the annular space pushes the piston with the liquid column above it out to the wellhead.

The liquid enters the collection system.

The frame shows the installation, the power supply cabinet.

The picture shows a type of elevator, which is designed to extract oil from wells with a diameter of at least 146 mm, up to 1800 m deep.

Close-up - a drill is lowered into the well.

The frame shows an elevator for oil production, the work is shown, the drill is lowered to a depth.

The underground equipment is a two-row compressor lift with a replacement chamber, a receiving valve and a saddle.

The work of the underground equipment is shown.

The cable is unwound.

At the end of the second row of pipes there is an inlet valve equipped with a rubber cuff.

The ground equipment includes a fountain-compressor valve with an automatic control station.

In the frame - a metal box with instruments and automation.

Animation insert - the principle of operation of the elevator.

Through the opening intake valve, the liquid fills the replacement chamber.

In the frame - instruments.

The time relay is triggered.

The valve closes and the working agent is supplied to the annular space, which displaces the liquid to the surface.

In the frame - instruments.

The machine is triggered, the working agent is cut off.

Close-up - the dial of the instrument, the arrow at 20. The picture is an elevator, which is designed for periodic compressor operation of low-flow wells up to 3500 m with a low dynamic level.

In the frame - an installation for low-flow wells.

Close-up - a detail of the installation.

Animation insert - under the pressure of the liquid column of the annular space, the intake valve opens, and oil fills the replacement chamber.

Close-up - equipment and devices in a special box.

On command from the time relay, the automatic control station supplies compressed gas under the piston connected to the pipes of the second row.

The pipes rise, opening the inlet valve.

The pressure in the chamber increases, the intake valve closes.

Oil is forced to the surface.

Close-up - the time relay device.

Control panel with devices.

The number of cycles of the elevators is set depending on the geological and operational characteristics of the wells.

Replacement elevators, due to the removal of back pressure on the well bottom, provide an increase in production by two to three times.

In the frame - the cabinet of the power supply side of the unit, a worker approaches it.

Field, in the frame - oil rigs, pumps and other equipment.

The operation of the elevator-pump is shown.
