There are various reasons for subeconomic wells in oil and gas exploration, including the
problems of geology, engineering and management, among which the most common …

The exploration degree of Sinian in the Sichuan Basin is low according to drilled information
analysis. The drilled wells distribute on Leshan-Longnüsi paleo-uplift area and orogenic belt …

Abstract The Sichuan Basin has been known to be rich of oil and gas resources, and after
the exploration and development for more than 70 years, oil and gas reservoirs (mainly gas …

Abstract In the West Sichuan Depression with tight sand, the formation mechanism of traps
and gas reservoir is quite complicated, resulted from the basin's complex evolution. Even in …

The Western Sichuan Depression of the Sichuan Basin is qualified for deep basin gas
accumulation due to basin types, hydrocarbon source rock characteristics, reservoir-source …

With large amounts of analytical data on oil and gas, the author approciates and supports
the deep inorganic genesis theory of oil and gas, in which it is suggested that the upwelling …

In recent years, a series of progress and breakthroughs have been made in the conventional
and unconventional natural gas exploration in the Sichuan Basin, and the geological …

After looking back the oil and gas exploration history and summarizing the geological
understanding, engineering technology and important exploration results in the Hailar basin …

The old Sinian carbonate reservoir in the Leshan-Longnüsi paleohigh was taken as a
research object to study the process of gas accumulation in the Sinian reservoir through …

The observation of core and thin section and analyses of organic geochemistry and statistics
showed that oil-bearing quality of paleo-oil reservoirs and gas-bearing quality of present …
