The technical enter of DESHI GROUP was founded in 2004, it is Shandong enterprise technology center, Shandong engineering research center, "one enterprise one technology" research and development center in Dongying. Its major work is to research on improvement recovery effeciency of heavy oil reservoir, conventional reservoir, low-permeability reservoir, to research and develop chemicals of tertiary oil recovery in the lab, to transform part of the research results to pilot amplification and industrialization transformation, to inspect product qualify, to improve technical process, etc.

For many years, the technical center has adhered to the strategic route of science and technology, which combines industry-university-research, and has formed seven core technologies. Seven core technologies are, the comprehensive treatment technology of tertiary oil recovery produced fluid, Nitrogen foam flooding and active water flooding technology in low permeability reservoir, surfactant-polymer flooding in conventional reservoir, CNS thermal chemical of compound oil recovery technology, crude oil desalination and dehydration technology under harsh conditions, demulsification - water clarification integration process technology, the resource utilization technology of heavy oil wastewater.
