The largest bottom-water oil field in production in the Bohai Sea has produced more than 45 million tons of crude oil.

It is reported that the Caofeidian Oilfield is located in the western waters of the Bohai Sea in my country. It was officially put into production in 2004. It mainly consists of 5 oil field blocks. It is the first Bohai Oilfield to use horizontal wells and separate sand bodies. developed oil fields. The oil field has a special geological structure. The oil reservoir types are mainly lithological structure edge water reservoirs and massive bottom water reservoirs. The edge and bottom water are active and the oil and water distribution is complex. It is a typical "oil fishing" oil field in the Bohai Sea.

According to reports, facing the challenge of ultra-high water cut, Caofeidian Oilfield has carried out technical research, actively explored large-scale water control and oil stabilization treatment measures for ultra-high water cut oil wells, and continued to strengthen refined management of oil and water wells. , accelerating the promotion of unmanned platform construction projects, and taking multiple measures to ensure long-term, high-quality, low-cost and sustainable development of oil fields. In the 20 years since it was put into production, it has contributed more than 45 million tons of crude oil and more than 1.5 billion cubic meters of natural gas, which can be used by a population of tens of millions of large cities. About 9 years.

While boosting offshore oil and gas reserves and production, Caofeidian Oilfield adheres to the concept of green development and is one of the first offshore oilfields in my country to fully connect to shore power. It is the first to realize traditional fuel power generation. Pattern changes. In 2023, Caofeidian Oilfield was rated as a "green factory" in the petroleum and chemical industry and became a "new model" for the development of my country's offshore "green oil fields".
