Thermal recovery of heavy oil is the main method for the development of heavy oil, which is widely applicable to shallow heavy oil below 1500 meters. However, deep heavy oil reservoirs have been plagued by high gas injection pressure, difficulty in lifting, and high costs, and have not been able to achieve large-scale development.
Advantages:
1. Having a functioning active 35MPa supercritical steam generator;
2. A comprehensive evaluation system for the research and development of heavy oil chemical agents, with a comprehensive sample library of heavy oil chemical agents in China;
3. Deshi Group has the ability to carry out large-scale heavy oil thermal recovery construction and comprehensive supporting capabilities. It has the ability to repair wells, sidetrack drilling, sand control filling, steam injection, nitrogen gas construction, and equipment maintenance supporting capabilities. It is one of the advanced heavy oil development service enterprises in China.
Deshi Group has closely integrated with Sinopec Northwest Bureau to conduct targeted research on the A5-1 well of the ultra deep heavy oil well in Block A of Tahe Oilfield, and successfully implemented the world's first 6000 meter deep heavy oil thermal composite throughput construction. This ultra deep heavy oil, ultra-high pressure, and high-temperature steam injection is the first of its kind both domestically and internationally.
