On December 2, the Longdong Shale Oil Demonstration Area of Changqing Oilfield in China broke through 1000 tons of crude oil per day and will have an annual production capacity of 500,000 tons of crude oil by the end of the year.
Since the construction of the Longdong Shale Oil Demonstration Area in Changqing Oilfield began in 2018, a total of 97 horizontal Wells have been put into operation through continuous technological breakthroughs and integrated innovation, with 43 Wells producing within 3 months of normal production, producing 17.1 ton of oil per day at the initial stage.Among them, 14 Wells have an initial oil production of more than 20 tons, and 1 well has a daily oil production of more than 30 tons, showing obvious development effect.
In recent years, with the development of exploration and development in Ordos Basin, unconventional oil and gas reservoirs have become the focus of exploration and development in Changqing Oilfield.Chang7 shale oil reserves in Longdong oil area are rich, but the reservoir grade is low, the physical property is poor, the exploitation is difficult, the traditional development technology cannot realize the benefit development.Demonstration Area construction unit depends on the national science and technology major projects, in order to "national oil shale development demonstration base construction, explore new model loess tableland geomorphic factory work, form a new intelligent labor organization management architecture" as the overall objectives, in Longdong region (Qingcheng Oilfields) formally to carry out the shale oil scale development demonstration area construction.
In development and construction, project in accordance with the "a platform, a factory" train of thought, the executive director responsibility system, through the "assessment of platform design, the production organization, process, investment control, security, environmental protection" accountability -such as sinking, realize the combination of the platform construction and production, promote the project management level. Face the long horizontal well enhance the fracture reservoir drilling rate, volume yield, large-scale factory operations efficiency, effective investment control and so on many challenges, project group projects of joint scientific research unit and unit, set up the integration of scientific research team, to form a integrated project management structure, promote the integration of production and operation organizations, to boost the oil one million tons of bulk density for the construction of the demonstration zone.

Currently, Longdong Changqing Oilfield Shale Oil (density) Demonstration Area overall development effect is better than expected, explore the formation of the Ordos Basin shale oil development of five series of 18 supporting technology, platform management system, in whole life cycle of the loess tableland factory operating mode, geological engineering integrated model of remote expert decision support system and so on characteristics, become the one's speciality of the development of shale oil, unconventional oil and gas field development of our country has the technology leading and demonstration role in driving.
