BEIJING, Dec. 11,
2024 /PRNewswire/ -- China Petroleum &
Chemical Corporation's (HKG: 0386, "Sinopec") has successfully
obtained ISO's approval for the Technical Specifications for
Multi-element Thermal Composite Flooding of Heavy Oil (the
"Technical Specification") proposed by academician Sun Huanquan's
team. Leveraging Sinopec's independent innovative technologies, the
Technical Specification is China's
first to receive approval in the field of heavy oil thermal
recovery and will promote international technical cooperation and
global heavy oil development upon release.
Heavy oil refers to crude oil of high density and viscosity, and
it is a key petroleum resource accounting for 36 percent of global
proved oil reserves. The heavy oil is also an important raw
material for specialty oils, and the naphthenic heavy oil, coined
as the "rare earth" of oil, is a high-quality raw material for
producing asphalt and transformer oil. China's annual production of heavy oil has
exceeded 15 million tons for 13 consecutive years.
Due to land-phase sedimentation and complex geological
conditions, China's heavy oil
reserves are buried deep with thin oil layers, so the developments
are facing challenges such as flow speed and distance. With the
support of the National Natural Science Foundation of China and Sinopec's key science and technology
projects, Sun Huanquan's team focused on tackling the bottlenecks
of heavy oil development and innovated the multi-element thermal
compositive development technology that has been applied on a large
scale in Shengli and Henan
oilfields, which enables Sinopec to achieve annual heavy oil
production of over 4.8 million tons.
Next, Sun Huanquan and the team will set up an international
working group with technical experts from the U.S., Saudi Arabia and other countries following
ISO's requirements to speed up the drafting of the international
standard and release it at the earliest availability.
