Classification of Newly Found Oil-Bearing Layer of Well Hongnan 9-12 in Tuha Basin

Abstract

Abstract: A new set of oil-gas bearing layer between Sanshilidadun formation of Lower Cretaceous and Kalazha formation of Upper Jurassic has been found in Honglian oil field in Tuha basin. This paper presents the correlation and demonstration of several opinions on the new oil-gas bearing layer classification based on the integration of multi-disciplinary information such as core, logging and seismic features. It is concluded that the new oil-gas bearing layer is located above the unconformity between the Cretaceous and the Jurassic, and should be classified into Sanshilidadun formation of Lower Cretaceous. The new oil-gas layer could be as a favorable target for further exploration for it is of basic conditions of hydrocarbon accumulation in this area.

Key words: Tuha basin, unconformity, Cretaceous, clay, heavy mineral, sequence boundary
