摘要
The oil and gas reservoirs have been divided in three types: millimeterpore,micropore and nanopore. Based on the field emission SEM and the nano CT reconfiguration technique, it was the first discovery of nano-pore in research of unconventional tight sandstone and shale gas reservoir in China, whose diameter is less than one micron. The discovery of nano-pore system within oil and gas reservoir has changed the traditional understanding that the micron-pore is exclusive. It also provided the significant scientific value with understanding geological characteristics of conventional oil and gas local accumulation, unconventionally continuous petroleum accumulation, develop petroleum accumulation mechanism and increase the potential of resources.
