Abstract

Abstract

Based on comprehensive understanding upon the drilling strata and the characteristics of hydrocarbon source rocks of Yihe exploration area in Manit depression of Erlian basin, hydrocarbon exploration potential of this basin has received large attention in recent years. This paper provides Permian hydrocarbon information from well-drilling data and hydrocarbon reservoir test, combined with comparative analysis of crude oil physical properties and geochemical characteristics between different well areas. It indicates that the natural gas obtained from the Well YH3 and the light crude from the Well YH8 has nothing to do with Mesozoic hydrocarbon source rocks. Besides, this paper discusses the information of hydrocarbon occurrence which is related to Carboniferous-Permian source rocks, thus providing an important clue in response to geological survey and exploration for Carboniferous-Permian hydrocarbon resources in Erlian basin.
