Abstract

Abstract: In view of paleogeomorphology controlling the formation and distribution of karst reservoirs, this paper explored the application of paleogeomorphic genesis assembly identification method to restore the pre?Carboniferous paleokarst landform in the major blocks of Tahe oilfield. Firstly,4kinds of two?grade geomorphic units (karst platform, karst slope (upper), karst slope (lower), karst intermountain basin) are presented, and then landform identification factors are added to further divided the paleokarst landform into10kinds of three?grade geomorphic units, by which the identification precision of paleogeomorphic landform can be improved. Also, combined with the karst development features and hydrocarbon reservoir properties in micro?geomorphic units, the relationship between petroleum production and geomorphology is analyzed to provide powerful basis for prediction of karst reservoirs in Tahe oilfield
