It was learned on February 6 that my country’s first self-developed submarine water injection tree, the core equipment of offshore oil underwater production, was successfully put into use, further verifying the safety and reliability of the equipment and marking that my country’s offshore oil industry is helping old oil fields. It is of great significance to drive the development of offshore oil and gas related industries and promote the high-quality development of my country's offshore oil industry.
The subsea water injection tree is one of the core equipment of the oilfield underwater production system. According to reports, the submarine water injection tree put into use this time is 3.5 meters long, 3.2 meters wide and 3 meters high. The overall weight is nearly 22 tons. It is expected to increase the production of crude oil by 50,000 tons. It is lightweight and low-cost and can be widely used in Shallow waters.
As time goes by, the recovery rate of old oil and gas fields gradually decreases, and it is often necessary to rely on water injection, gas injection and other production methods to increase the recovery rate and achieve high and stable production of the oil field. Submarine water injection trees are like "syringes" that inject energy into the "capillaries" of the formation, driving the oil and gas in low-pressure and low-permeability oil and gas reservoirs to flow to designated locations to obtain higher oil and gas recovery rates.
