Located in the west of Heilongjiang Province, in the middle of Songnen Plain, between Harbin and Qiqihar. The oilfield is 0/40km long from north to south and 70km wide from east to west, with a total area of 5,470 square kilometers. In 1976, the crude oil output exceeded 50 million tons. By 1996, the annual crude oil output had been 50 million tons continuously, with a stable output of 2 1 year. 1995 produced 56 million tons of crude oil, which is the largest oil field in China.

2. Shengli Oilfield

The Yellow River Delta, located on the Bohai Sea in northern Shandong Province, is mainly distributed in 8 cities and 28 counties (districts) such as Dongying, Binzhou, Dezhou, Jinan, Weifang, Zibo, Liaocheng and Yantai, with a main working area of about 44,000 square kilometers. 1995 produced 30 million tons of crude oil, making it the second largest oil field in China.

3. Liaohe Oilfield

Oil fields are mainly distributed in the middle and lower reaches of Liaohe plain, eastern Inner Mongolia and Liaodong Bay beach area. Twenty-six oil fields have been developed and constructed, and nine production bases have been built, including Xinglongtai, Shuguang, Huanxiling, Jinzhou, Goldman Sachs, Shenyang, Ciyutuo, Lengjia and Horqin, covering 32 counties (banners) in Liaoning Province and the Inner Mongolia Autonomous Region 13 cities, with a total area of nearly 654.38 million square kilometers. 1995 crude oil output15.52 million tons, ranking third in China.

4 Karamay Oilfield

Located in Karamay, Xinjiang. Over the past 40 years, 19 oil and gas fields have been discovered in Junggar basin and Tarim basin, mainly in Karamay, and 15 oil and gas fields have been developed, with a supporting crude oil production capacity of 7.92 million tons (603 1 10,000 tons of thin oil and 0.889 tons of heavy oil) and a natural gas production capacity of 393 million cubic meters. Since 1990, the onshore crude oil output ranks fourth in China. 1995 produced 7.9 million tons of crude oil.

Origin of the name of Shengli Oilfield:

1961April 16, the Hua 8 well near Dongying village was drilled, and the industrial oil flow was first seen, with a daily crude oil output of 8. 1 ton, which opened the prelude to the oil field search in North China Basin.

On September 23rd, 1962, Dongying structure drilled into Ying 2 well, with a daily output of 555 tons, which was the highest in China at that time. The "923 Factory" originally named by Shengli Oilfield came from this.

1964 65438+1October 15. The Ministry of Petroleum decided to organize an oil battle in North China. North China Basin is located at the southern foot of Yanshan Mountain, east of Taihang Mountain and north of Tai 'an, with an area of 6,543,800 square kilometers. During the battle, the battle of Tuozhuang-Shengli Village was carried out.

196565438+1October 25th, Shengli Village structure, drilling team drilled Tuo1/well, and found an extremely thick oil layer of 85m. The daily production of oil testing is 1 134 tons, hence the name "Shengtuo Oilfield". After three years of fighting, Shengtuo, Dongxin, Jiahao, Chunhua and Shangdian oilfields were discovered successively, making "923 Factory" the second largest oilfield in China at that time. In view of the fact that the first 1000-ton oil well in China was drilled in Shengli Village,1971June 1 1, "923 Factory" was officially renamed as Shengli Oilfield.

After years of efforts, the crude oil output of Shengli Oilfield reached19.46 million tons in 1978, making it the second largest oilfield in China. However, in recent years, the crude oil output of Shengli Oilfield has shown a downward trend, and the crude oil output in 20 10 is 27.34 million tons. At present, it is the fourth largest oilfield in China and the third largest oilfield on land.
