China News Service, Urumqi, February 27 (Chen Chuansong, Zhang Rui, Ye Yu) Reporters learned from the Xinjiang Oilfield Jiqing Oilfield Operation Area on the 27th that in recent years, the Jiqing Oilfield Operation Area has continued to promote the construction of a national-level continental shale oil demonstration area and continuously strengthened scientific and technological research. , innovative production methods, and through two-way efforts in technology and management, shale oil production will reach 635,000 tons in 2023, achieving efficient production construction.

On the 57D drilling platform in the Jiqing Oilfield operating area, workers from the Western Drilling Zhundong Drilling Company are conducting secondary drilling operations. The completion of the drilling platform will represent the complete completion of 31 new horizontal wells in the area, preparing for later fracturing and production Lay the foundation.
It is understood that in 2023, the Jiqing Oilfield operating area will continue to optimize the production time rate of new wells. A total of 72 shale oil production wells have been drilled, a new production capacity of 429,000 tons has been built, and a total of 55 new wells have been put into production.
Currently, the daily output of shale oil exceeds 3,000 tons, a new breakthrough.
Shale oil is an unconventional oil and gas resource with low permeability and poor fluidity. It is one of the most difficult oils to extract. The industry describes it as "squeezing oil out of rocks."
Relying on technological innovation, the Jiqing Oilfield operating area actively explores "stuck neck" technology and establishes a "golden target" identification standard for Jimusar shale oil.
At the same time, we have introduced a market competition mechanism, comprehensively promoted factory-based operations, and continuously improved our core competitiveness in technology and management. Now we have relevant supporting experience in drilling, fracturing, oil production and other technologies.
Peng Tianhao, assistant engineer of the Geological Research Center of the Jiqing Oilfield Operation Area, said: "Through the two-way efforts of technology and management, the 'golden target body' drilling rate increased from 43.4% to 83.6%, and the resource utilization level increased from 50% to 89%. Drilling, The market-based competition model was introduced for fracturing, and the comprehensive investment in a single well was reduced to 45 million yuan.”

As a model for exploring the benefits of shale oil production in Xinjiang oilfields, the Jiqing Oilfield operating area will continue to improve the efficiency of development and utilization of important energy resources, continuously optimize various process parameters, and improve core competitiveness to promote Xinjiang’s energy production increase and create a national energy resources strategic guarantee The base plays an important role.
"We will actively implement the relevant requirements and work arrangements of PetroChina's shale oil revolution, and resolutely win the 'three hundred' battle for the construction of the demonstration zone, which means to drill 100 horizontal wells in the Jimusar shale oil well area and press 110 fractures will be completed to achieve a production capacity of one million tons of Jimusar shale oil in 2024." said Ran Yang, director of the Geological Research Center of the Jiqing Oilfield Operation Area of Xinjiang Oilfield.
