With the consumption of conventional petroleum resources, the exploration and
development (E&P) of unconventional hydrocarbons in recent years have supplemented the …

Shales deposited in marine–continental transitional environments are well developed in the
Upper Paleozoic in China with abundant gas resources. The pore structure and its …

Sea level changes more frequently during the deposition of transitional shale than marine
shale, resulting in the strong heterogeneity and instability of the sedimentary environment …

Longmaxi formation shales are the major target reservoir for shale gas extraction in Sichuan
Basin, southwest China. Swarms of earthquakes accompanying hydraulic fracturing are …

The pore structure of shale has a significant effect on hydrocarbon migration and the long-
term gas supply of shale gas wells. The present study investigates the spontaneous …

Continental shale is abundant with unconventional oil and gas and has considerable
potential for exploitation. However, due to differences in the deposition environment …

Pore connectivity of shale is a critical factor in shale gas migration and production. In order
to investigate the pore connectivity from three typical shale formations in south China …

Brittleness is a significant indicator of a series of engineering problems in the oil and gas
community. However, the majority of brittleness evaluation methods focus on brittle rock, but …

Rock mechanical properties are of crucial importance to shale reservoirs as they directly
affect the production efficiency and hydraulic fracturing design. However, limited data exists …

页岩气富集不均匀, 无论对于不同页岩油气藏还是同一页岩油气藏不同地方, 产量都是有高有低.
有必要系统分析和对比全球不同页岩油气的地质, 石油系统与油气富集的关系 …
