Abstract:

Yanchang Formation is an important hydrocarbon-exploring layer in Zhenyuan and Jingchuan area in southwestern Ordos Basin. Based on core observation, well log analysis, thin section analysis and conclusion of oil testing, the oiliness of Chang 62 reservoir is discussed. The result indicates that Chang 62 is a delta-lacustrine depositional system, and the principal producing pay is in subaqueous distributary channel where deposit fine sandstones and have good physical properties. The areas in the center of subaqueous distributary channel get high oilproduce while the flanks get lower oil-produce relatively. The distribution of oil layer is mainly controlled by lithology, and Chang 62 is lithologic reservoir developed in the monocline setting which cline to the northwest. Reservoir exploitation presently focuses on the upside ofChang 6 2- 2, and the transition zone carrying remaining oil can be prospected and exploited in the next step.

Key words: buried hill, internal structure, hydrocarbon trap, oil-source correlation, hydrocarbon migration, hydrocarbon accumulation model, Western Liaohe Sag
