China's Offshore Oil Field Development Projects of 100 Million Tons Have Been Completed
China National Offshore Oil Corporation announced on September 24 that China's offshore oil field development project of 100 million tons - Kenli 6-1 oilfield drilling and development project has been completed, and the current oil field has reached the scale of nearly 10,000 cubic meters of daily crude oil.
According to CCTV news, Kenli 6-1 oilfield is located in the southern waters of Bohai Sea, with proven geological reserves of more than 100 million tons of oil. It is the first large lithologic oil field of 100 million tons discovered in the shallow layer of Laibei low bulge in Bohai Sea in China.
The field's drilling development program consists of three blocks with 177 Wells drilled on nine drilling platforms. At the same time, this is also China's offshore drilling so far the largest scale, the shortest time, the most platform development project.
At the same time, this is the first oil field in domestic waters to use shore power to power drilling platforms. It uses the grid shore power supply to replace the traditional diesel power generation of offshore drilling platforms, which can significantly reduce diesel consumption and effectively reduce carbon dioxide emissions: a single platform can achieve an annual reduction of nearly 10,000 tons of carbon dioxide emissions.
The reporter previously reported that the Bozhong Kenli Oilfield group shore power application project achieved a key milestone in December last year: China's largest offshore shore power application project 220 kV / 110 kV high voltage submarine cable and three offshore electric power platforms were successfully delivered.
The land substation is an important node in the construction of shore power application project. Through the introduction of 220 kV high voltage electricity from the National Grid, the land substation is transferred to the offshore substation and converted into 35 kV alternating current used by the offshore production platform, which provides kinetic energy for the production and life of the maintenance platform.
