The deepest oil well in the world has reached a depth of15000 metersChaivo Oilfield Orlan Platform2.3 billion barrels.

However, although it is at sea, its depth is onlyDozens of meterswell drilling.

How is underwater oil extracted?

Simply put, it meanswell drilling.

Survey oil layers

The first person responsible for surveyingSeismic survey vessel, utilizingacoustic waveDetermine which sea area has oil underneath, and then conduct basic drilling to determine the specific location of the oil field. Then, one will be brought in or towed inwell drilling;

Blowout preventer

During this process, in order to ensure that the underwater oil field does not gush out at the moment of drilling through, it is also necessary to install at the junction of the seabedBlowout preventer;

In the wellOil and gas pressure.

Whether it's offshore oil production or onshore oil field oil production, there will always be apipelineContinuously spewing fire, with flames stretching longDozens of meters.

Why is there a pipe that keeps spewing fire while extracting oil?

So it will be directly burned, simply by placing it in a containerGas-liquid separation, utilizingCombustion nozzle.

Why not collect natural gas?

The fundamental reason is thateconomic benefits.

If you want to collect, you need to separate it first, which requires adding an additional setNatural gas separation system;

However, with the development of technology and the demand for environmental protection, more and more countries have begun to regulate this part of natural gasrecovery.
