Jiebeitong supramolecular self-crosslinking fracturing fluid with integrated pressure driving technology helps Nanyang Oilfield set a new record of over 100 tons of crude oil per day per well!
On May 18, 2023, the Jie219ping1 well, a horizontal well for tight oil development in the Nanniwan Oil Production Plant of Yanchang Oilfield, achieved a daily oil production of 123.5 cubic meters after fracturing, setting a new record for the plant's highest single-well daily oil production.
The Jie219ping1 well is located in Hezhuangping Town, Baota District, Yan'an City, Shaanxi Province. Its horizontal section is 546 meters long and was fractured in 8 stages. A Jiebeitong supermolecular self-crosslinking fracturing fluid system replaced the previous guar gum fracturing fluid system. All fracturing fluids were prepared using recycled fluid, and high-sand content was used during construction. After 8 days of continuous work, a total fluid volume of 5508 m³ and 440.0 m³ of sand were injected, successfully completing the 8-stage fracturing construction and meeting all the technical requirements of the construction design.
The high yield obtained after fracturing the Jie219ping1 well fully demonstrates the advantages of the Jiebeitong supermolecular self-crosslinking fracturing fluid: This system uses only one additive, making on-site construction convenient. It has good drag reduction, strong sand-carrying capacity, and excellent salt resistance. It can use 100% recycled fluid for mixing, and high-sand content construction can be achieved even at low displacement rates. Especially, this fluid has good breaking properties at low temperatures. The broken gel molecules are small in size and have strong surface activity, with the ability to alter core wettability and reduce oil-water interfacial tension. Its spontaneous imbibition displacement and oil displacement capacity is strong, significantly improving single-well output. Next, Jiebeitong will continue to optimize the fluid formula, continuously innovate, overcome difficulties, and provide more advanced technology for China's oil and gas production increase!
