Classification evaluation method for Chang 7 oil group of Yanchang formation in Ordos Basin [PDF]
Journal of Petroleum Exploration and Production Technology, 2021 AbstractThe Chang 7 oil group in the Ordos Basin has the characteristics of a tight lithology, a low formation pressure coefficient and strong reservoir heterogeneity. To better determine reasonable developmental technical countermeasures, oiliness, seepage capacity, and compressibility evaluations are combined.

Formation patterns of Chang 9 oil reservoir in Triassic Yanchang Formation, Ordos Basin, NW China
Petroleum Exploration and Development, 2018 Abstract: Based on analysis of main controlling factors of Chang 9, the source rock, driving force of migration, migration and accumulation modes, reservoir forming stages and model and enrichment law of Chang 9 reservoir were examined. The study showed that the oil of Chang 9 reservoir in the Jiyuan and Longdong (Eastern Gansu) areas came primarily ...

Fracability Evaluation of Lacustrine Shale in the Yanchang Formation of Southeastern Ordos Basin [PDF]
Energy Exploration & Exploitation, 2015 As a typical lacustrine shale in China, the Chang 7 shale in the Yanchang Formation of the Ordos basin shows great potential for development. Buried less than 2000 m deep, the shale is always characterized as a tight reservoir with well-developed bedding and cracks.
