Deep exploration of gas wells (1988)

Panorama of the plant territory.

Gas well.

Cartoon explaining the tasks solved with the help of deep exploration of gas wells.

Special machines are used for deep exploration.

The device of such a machine is shown.

The set of equipment of the machine includes deep measuring devices, electronic remote measuring devices, which include a flow meter, thermometer, pressure gauge, etc.

Ground control panel for devices.

A lubricator and a deep winch are used to lower the devices into the well.

Winches are single-drum with wire for lowering standard devices.

Double-drum winch with wire and single-core logging cable for lowering electronic devices.

A device for uniformly laying the wire on the drum and a special counter showing the depth of the measuring device.

The deep exploration team consists of two operators and a driver.

Complex gas treatment unit.

The machine is located at a distance of at least 25 meters from the well and necessarily on the windward side.

A work platform next to the wellhead equipment, eliminating the possibility of slipping and necessarily with railings.

The platform is at a height of at least 1.25 cm with longitudinal strips located no more than 40 cm from each other.

A worker checks the serviceability of the wellhead equipment.

Tee and cross-type equipment.

A cartoon explaining the course of research.

To lower the measuring devices into the well, the buffer is removed and a lubricator is installed.

A cartoon explaining the design of the lubricator.

Work crews install the lubricator.

A template is lowered into the well to check the cleanliness of the tubing.

A cartoon explaining the use of the template.

The sequence of operations when using the template.

A cartoon explaining the operations for which the template is used.

A downhole pressure gauge, which is used to measure formation and bottomhole pressure.

A cartoon explaining the design of a downhole pressure gauge.

A cartogram is inserted into a special drum to record readings.

To simultaneously measure bottomhole or formation temperatures, a thermometer is inserted into the pressure gauge.

Preparing the device for lowering into the well.

A cartoon explaining the pressure measurement process.

Decoding the cartogram.

The results of the research are formalized in a report.

Gas well.

Deep-well thermometer for measuring temperature along the wellbore and identifying gas-emitting intervals.
