After watching the news of the giant oil field found in the United States, today, the small editor is coming to give you an inspiring spiritual food: China oil Qinghai oil field will be born fifth million tons of oil and gas fields! It seems that God is not the only blessing of this land, we China is also a treasure pot!

Recently, the exploration and Development Research Institute of the China Petroleum Qinghai Oilfield Company has reported that the deep exploration in Qinghai oil field has successfully drilled 5 high-yield wells with more than one thousand tons of oil and gas equivalent for more than one year. This indicates that another oil and gas field of another billion ton reserves is about to be born.

The western part of the Ying Xi is the heroic ridge structural belt in Qaidam basin with an exploration area of 2600 square kilometers, with an average depth of about 4600 meters. The average area of the western exploration area is more than 3200 meters, the geological structure is very complex, and the exploration difficulty and exploration risk are huge. For the past 30 years, the deep exploration in western England has not seen much success. The successful production of 5 high yielding wells has made Yingxi a more than 100 million ton scale oil and gas field after kunbei, Yingdong, Dongping and Zaha springs.

According to Bao Yuandun, the director of the three oil production plant in Qinghai oilfield, in November 28th, the five wells in five wells produced 62 thousand tons of crude oil and 12 million cubic meters of gas. One stroke became the highest yield, the longest stable production time, the fastest return on investment, and the efficiency of the investment of the Qinghai oil field for 30 years in the lion valley of the hero ridge block. The best productive oil well.

We know that the main exploration and development field in Qinghai oilfield is in the Qaidam Basin known as "the treasure basin", which is one of the most important areas of the land oil and gas exploration in the whole country. The Qaidam Basin is one of the seven inland oil and gas basins in China with a geographical area of about 250 thousand square kilometers, the area of sedimentary rock 120 thousand square kilometers, and the largest thickness of the sedimentary rock more than 17000 kilometers. The average oil area is more than 2900 meters above sea level. The oxygen content in the air is only 70% of that in the mainland. It is one of the most difficult natural conditions and working conditions in China. By the end of 2010, 23 oil and gas fields were discovered. Among them, the Shibei gas field is one of the four atmospheric regions in China. At present, 6 gas transmission pipelines and "flower - lattice" oil pipeline have been built, such as Xining, Lanzhou, Yinchuan, Beijing and other cities, which are the main gas fields of winter supply.

The lion 205 well, which was discovered in the western exploration area, is an evaluation well deployed in the western Qinghai area in 2016. The design depth is 4600 meters. The well was drilled in March 8, 2016, and a good oil and gas show was found when drilling into 3598 meters in June 1st. In June 6th, the naked eye was put into operation. It is currently produced by 12mm nozzle, 29MPa, Nissan crude oil about 1089 cubic meters, Nissan natural gas 96438 cubic meters.

Prior to this, the Qinghai oilfield has captured "lion 38 well" and "lion 1-2 well" in the British West exploration area successively. Lion 38 well finished drilling 3804 meters deep, with 8 millimeter nozzle production, oil pressure 25MPa, Nissan crude oil 605 cubic meters. Lion 1-2 well finished drilling 3004 meters, with 20 millimeter nozzle production, oil pressure 13.5 MPa, Nissan crude oil 912 cubic meters, natural gas 110 thousand cubic meters.

He Haiqing, deputy general manager of China Petroleum Exploration and production branch, said that 5 oil and gas production equivalent ultra thousand tons of oil and gas in deep exploration in Qinghai oilfield is the most concentrated area of high production wells in recent years, and three tons of new oil and gas reserves are more than 100 million tons, very inspiring.
