BEIJING – Recently, Jereh Group launched the new Allison-equipped 2500 model fracturing truck at its Yantai headquarters. Engineered to be compact, rugged and reliable, this new truck employs the Allison 9832 OFS™ transmission, reducing overall vehicle weight by 2.5 tons, decreasing the length by a full meter and improving fuel economy by 5 percent compared to the previous truck.
With the energy industry facing increased challenges and the market for unconventional oil and gas reserves becoming increasingly complex, demand for more powerful, dependable oil field fracturing equipment is expected to grow. The Allison 9832 OFS rated at 3,200 horsepower (2,386 kW) is designed to deliver continuous torque and maximum horsepower for pressure pumping in the most difficult environments.
“The 9832 OFS model is up to 44 percent lighter than any alternative on the market, providing an unprecedented power-to-weight ratio, in addition to uncompromising quality,” said Chris Vargo, managing director of global off-highway marketing, sales and service for Allison Transmission during the unveiling at the China International Petroleum & Petrochemical Technology and Equipment Exhibition in 2015.
As a leading, high-quality oilfield equipment manufacturer in China, Jereh Group is committed to solving the practical problems facing global oilfield development through the launching of collaborative research-driven solutions.
The newly launched 2500 model fracturing truck equipped with an Allison 9832 OFS fully automatic transmission is another step in providing the industry’s well sites with big solutions. According to Quan Jin, the head of project research and development for Jereh, Allison transmissions have impressed the industry with their efficiency, reliability and durability.
Thanks to the Allison’s lower gravitational center, the truck is safer and better adapted to harsh well site and mining road conditions. Service and maintenance has also been made easier as 90 percent of 9832 OFS parts can be used interchangeably with other Allison transmissions installed in conventional 2000 and 2300 model fracturing trucks, greatly reducing reserve part stocks at operational sites.
Jin said that prior to launch, the new truck was field tested for more than 300 hours in four shale gas wells in Sichuan Province. Since July 2015, results have shown increased stability, drivability and higher output volumes during operation.
"The Allison transmission makes the truck more maneuverable. With the truck weight and length reduced, the braking distance and turning radius are greatly improved resulting in the truck being better equipped for challenging road conditions,” said Jin. “The weight and length reduction also increased fuel economy by 5 percent, reducing transportation costs and extending chassis life.”
Recalling his observations during testing, Jin said the average operating pressure at these four wells was 65 million to 85 million Pascals (9,430-12,330 psi).
“Under such conditions, the new fracturing truck only experienced 46 to 55 percent of the load (ratio of operating power to rated power), achieving the same output displacement at three speeds that used to be done at four with the old model 2500 fracturing trucks,” he said. “Overall, the entire operation is safer, more stable and more efficient.”
