Abstract:

On the foundation of thin- section identification, cast analysis, special seismic treatment and experience data, this paper studies the characteristics of Ordovician reservoir in east upwarding and vicinity in liaohe basin, the contents include the lithologic characteristics, reservoir space types, porethroat structure and physical property. The authors conduct the further probe on the major factors, which control reservoir formation. The favorable factors include dolomizatopn and segmentation. In the end, authors point out Ordovician crust of weathering will be the important target in the further exploration.

Key words: Liaohe basin, east upwardinmg, Ordovician system, reservoir
