On May 26, China National Offshore Oil Group Co., Ltd. (hereinafter referred to as CNOOC) Kenli 6-1 Oilfield proved geological reserves of more than 100 million tons, and officially passed the reserve assessment work of the Ministry of Natural Resources. It has become the first large-scale oilfield with a capacity of 100 million tons in the northern area of Laizhou Bay, China. And in one fell swoop to break the situation of no commercial oil and gas discovery in the region for more than 40 years.
Kenli 6-1
The data shows that Kenli 6-1 oil field is located in the Laibei low uplift of the Bohai Sea, with an average water depth of about 19 meters. The structure completed 18 exploration wells in the first quarter of 2020, with an average completion depth of about 1,540 meters and an average thickness of about 12 meters. Kenli 6-1 Oilfield has the characteristics of large reserves, good oil products and high test production capacity. Its oil-bearing area exceeds 100 square kilometers.
Kenli 6-1 Oilfield belongs to Bohai Oilfield, China's largest offshore oilfield. Since the end of the 1970s, the region has experienced more than 40 years of rounds of exploration, and the results have been unsatisfactory. The discovered oilfields have small scales and are not concentrated in distribution, and an effective development system cannot be established.
In recent years, Bohai Oilfield researchers have faced the challenges and faced difficulties. They have made bold innovations in exploration theory and geological understanding, figured out the enrichment rules and exploration directions of oil and gas reservoirs, and obtained 100 million tons of proven geological reserves in the region oilfield.
Xue Yongan, chief geologist of CNOOC Tianjin Branch, said that the discovery of Kenli 6-1 oilfield is the result of CNOOC ’s emancipation of thinking and change of thinking in the exploration field, breaking the situation of no commercial oil and gas discovery in the northern area of Laizhou Bay for more than 40 years .
In the past two years, CNOOC has drilled 42 exploration wells in the field. It has been confirmed that Kenli 6-1 oilfield has the characteristics of large reserves, good oil products, high test production capacity, etc., and the oil-bearing area exceeds 100 square kilometers. According to the calculation of crude oil recovery ratio, after being refined into gasoline and diesel, it can be used for 1 million vehicles for more than 20 years.
It is understood that, at present, Kenli 6-1 Oilfield is accelerating development evaluation work and putting it into operation as soon as possible. The huge exploration prospects of the oil field will lay a solid resource guarantee for the Bohai Oil Field's continued green and stable production for 10 years and the realization of the target of 40 million tons of production.
In recent years, CNOOC has vigorously increased its domestic oil and gas exploration and development efforts, and launched the "seven-year action plan" for increasing oil and gas reserves and increasing production in early 2019. CNOOC Chairman Wang Dongjin said that Kenli 6-1 oilfield is an important achievement for the company to increase domestic oil and gas exploration and development. CNOOC will continue to play a leading role in exploration, with the main line of finding large and medium-sized oil and gas fields, and strive to be more complex More new breakthroughs have been made in oil and gas reservoirs and deeper seas.
