Early Paleozoic Extension‐Compression Transition and Formation of a Paleo‐Oil Reservoir System in the NW Sichuan Basin: Implications for Deeply Buried Hydrocarbon Accumulation

Geofluids, Volume 2021, Issue 1, 2021., 2021
Owing to multiple tectonic events after the Late Triassic, the northern segment of the western Sichuan depression (NSWSCD) has a complex geological history of significant uplift and deeply buried. With abundant oil and gas play in the NSWSCD, the study of paleo‐oil reservoir systems and early hydrocarbon accumulation in this area is of great ...
