Original Title: Annual Production Of China’s Largest Oil And Gas Field Breaks National Records
China has built a super-large oil and gas field with an annual production of 60 million tons of oil and gas equivalent three years ahead of schedule. At 10:00 am on December 27, 2020,China PetroleumChangqing OilfieldAnnual oil and gas production in 2020 will exceed 60 million tons, of which 24,518 million tons of crude oil and 44,531 million cubic meters of natural gas are produced. This is the largest oil field with the highest annual oil and gas production in China so far.China PetroleumindustryA new milestone was born.
China PetroleumChangqing Oilfieldthe companyExecutive Director, Party Secretary Fu Suotang said that in the last two rounds of ultra-low international matchesOil priceUnder pressure, Changqing Oilfield continues to challenge the limits of “unconventional” oil and gas development, relying on independent innovation to break the technology of foreign companies.monopoly, Master the key to horizontal well drilling and volume fracturingCore technologies, Overcoming the world’s problems in the development of tight gas and shale oil, allowing the “three low” oil and gas reservoirs to burst with enormous energy. It has successively built a nationwide one million ton shale oil demonstration zone and a 3 billion cubic meter compact gas efficient development demonstration zone. The forward speed of 60 million tons has accelerated, pushing China’s oil and gas development into an “unconventional” era.
So far, the cumulative oil and gas production in the Changqing oil field has exceeded 760 million tons. Industry experts believe that long-term stable production from a 60 million ton super-large oil and gas field gives China more voice in international energy cooperation.
A China Economic Times reporter learned that venture exploration has captured the first high-yield offshore shale gas well in North China. With the accumulation of resource advantages, the Changqing oil field still has great potential for sustainable development with a huge volume of 60 million tons. On the basis of the accumulation of these resource advantages, advances in key technologies, lowcostModel Innovation, Changqing OilfieldplanningDuring the period of the “XIV Five Year Plan”, the annual production of oil and gas will increase to 68 million tons.
stay in bedOrdosThe Changqing oil field in the basin has been the fastest growing oil field in China since the new century. Since 2012, it has become the largest oil and gas field in China. After the completion of Daqing in western China in 2013, it surpassed the historical peak of national oil fields in 2019. This year it reached a new height in China’s oil industry, creating a miracle of efficient gas field development. and unconventional oil from China. Oil and gas wells represent a relatively large proportion.
Fu Suotang revealed that the development of the Changqing oil field is a typical “three lows” (low permeability, low pressure and low abundance) oil and gas field in the world. Its notable characteristic is that “there is oil in the well, but the well is not flowing.” It is an economic and effective development. It is a global problem. Starting from a low permeability oilfield, Changqing Oilfield has overcome ultra-low permeability, re-attacked ultra-low permeability, released compact gas, and achieved effective large-scale development of shale oil. It has gone through almost 50 years of basic research and scientific research. Among them, only the Xifeng oil field with reserves of more than 400 million tons has experienced three exploration failures; the Jiyuan oil field with 500 million tons of reserves has failed six times. Technicians stick to the plateau and desert, focus on the laws of geological evolution and basic research on oil and gas generation for decades, and have formed five original theoretical understandings for the rapid acquisition of oil and gas resources. gas, and ultimately control the initiative for the basin’s oil and gas resources. Accumulated proven oil reserves are 5.9 billion tons and proven natural gas reserves are 4 trillion cubic meters.
The past two years have been a period of rapid growth for PetroChina’s Changqing Oilfield to increase reserves and production.MetersA large billion-ton shale oil field; Natural gas exploration has discovered two new areas with 100 billion cubic meter gas in Longdong and Ningxia, and has obtained a large area of carbonate rock with proven reserves of 212.4 billion cubic meters on the west side of the Jingbian gas field.
Fu Suotang stated that in the face of the reality of “multiple wells and low production” in the “three low oil and gas fields”, the exploration of the Changqing oil field has formed five kinds of low-cost development models of oil fields. and low permeability gas to ensurecompanyDevelopment has always been transformed in a more efficient, lower cost and more sustainable way.borrowSukeshin Ichidaiinformation technologyIt will integrate more than 900 innovative technologies applicable in the construction, production and production of oil and gas fields.administrationThe key link driving all oil and gas developmentindustrychainDigital transformationAnd smart upgrade, pullproduction methods, Management approach for newindustrializationThe transformation has eased pressure on oil and gas development costs and effectively hedged past international oil prices.PlumbBroughtOperatingrisk.
The production area of the Changqing Oilfield is spread over the five provinces (regions) of Shaanxi, Gansu, Ningxia, Mongolia and Jinan. As China’s largest natural gas production base, Changqing Oilfield is responsible for supplying gas to more than 50 large and medium-sized cities. The annual natural gas production of more than 44.5 billion cubic meters has formed a safe and stable gas source for the Beijing-Tianjin-Hebei region and the Shaanxi, Gansu, Ningxia and Mongolia regions.Since the official supply of gas in 1997, has produced 468.3 billion cubic meters of natural gas, which is equivalent to replacing 562 million tons of standard coal and reducing carbon emissions by 1.529 million tons.Ecological benefits。
