The Ordos Basin is the second largest petroliferous basin in China, located in the central part of the country. The basin’s petroleum resources are mainly accumulated in fluvio-lacustrine sandstone reservoirs of the Upper Triassic Yanchang Formation. The 800–1500 m thick Yanchang Formation was deposited during the Carnian and Norian stages (237.0–208.5 Ma) and is dominantly distributed in a gently dipping and mostly undeformed region of the southeastern Ordos Basin. Organic-matter (OM)-rich intervals in the Chang 7, 8, and 9 members of the Yanchang Formation are the sources of oil for the sandstone reservoirs. Given the richness of the OM-rich intervals,...
