Abstract EN
As a result of complex tectonic background, shale gas in China exhibits differential enrichment.
Choosing a favorable exploration target accurately is a crucial problem to be solved.
In this study, the tests show that there is a superior transportation pathway within shale layer.
Gas in the shale layer percolates much more in the direction parallel to the plane.
Therefore, the accumulation pattern of shale gas indicates a complex tectonic background.
Gas in the lower part of the structure diffuses and percolates in the vertical direction into the surrounding rock.
Most gas percolates towards the high part of the structure in the direction parallel to the plane.
When the shale was exposed, gas percolated along the parallel direction into the air.
In the case of fracture development, if there is a reverse fault, gas would be enriched in the footwall.
However, if there is an unsealed fault, it would become a pathway for gas migration.
The above accumulation pattern was proved in several Areas.
Also, this research presented a basis of evaluation units division.
According to the buried depth, fractures, and structural position, Xiuwu Basin was divided into five evaluation units and Unit A3 is the most favorable exploration target.
