Seismic exploration technology for tight oil and gas in China and its development direction
Tight oil and gas (TOG)resources are rich in the whole world
which have a history of exploration and development over a century. Currently
TOG has become an important contributor to increasing oil and gas reserve and production. Although China’s TOG exploration and development started late
it has been developing rapidly. After 50 years of exploration and development practices
China now has achieved large-scale commercial exploitation following the United States
and has become an important country in the word. Focusing on the geological-engineering needs of TOG in China
significant progresses of seismic technology have been made in continuous research and development
technological innovation and exploration practice
formed corresponding key technologies of seismic data acquisition
processing
and interpretation
which strongly supports the efficient exploration and development of TOG. This paper reviews the global TOG exploration and development process
briefly introduces the main geological characteristics and seismic technology needs of TOG
summarizes the development process and technical status of TOG seismic exploration technology in China
displays some typical application results
and prospects the future development of seismic exploration technology in view of the new needs and challenges of tight oil and gas exploration and development. High precision
intelligence
quantification and multidisciplinary integration are the inevitable trends of TOG seismic exploration technology development.
