  • In order to further clarify the role of different geological conditions on hydrocarbons accumulation process, the major controlling factors of Ordovician hydrocarbons accumulation in the Tazhong Uplift, Tarim Basin are studied based on the view points of diverse geological conditions and their relationship in space. The results showed that the vertical hydrocarbons migration distance and accumulation layers were controlled by vertical source-reservoir distribution, faults, and caprocks. Structures played a major role in lateral direction of hydrocarbons migration. The lateral migration pathways were governed by unconformities, transport faults, and porous permeable carrier beds. Apart from the excellent reservoir controls, hydrocarbons enrichment was controlled by tectonic events. Based on the analysis of factors mentioned above and coupled with oil sources conditions and excellent reservoirs, two types of hydrocarbon accumulation models could be retained based on the vertical hydrocarbon migration distance, including a multi-sourced area model and a single-sourced area model. In addition, the accumulation models could be also classified into near source accumulation and far source accumulation based on the lateral hydrocarbons migration distance.

Abstract: In order to further clarify the role of different geological conditions on hydrocarbons accumulation process, the major controlling factors of Ordovician hydrocarbons accumulation in the Tazhong Uplift, Tarim Basin are studied based on the view points of diverse geological conditions and their relationship in space. The results showed that the vertical hydrocarbons migration distance and accumulation layers were controlled by vertical source-reservoir distribution, faults, and caprocks. Structures played a major role in lateral direction of hydrocarbons migration. The lateral migration pathways were governed by unconformities, transport faults, and porous permeable carrier beds. Apart from the excellent reservoir controls, hydrocarbons enrichment was controlled by tectonic events. Based on the analysis of factors mentioned above and coupled with oil sources conditions and excellent reservoirs, two types of hydrocarbon accumulation models could be retained based on the vertical hydrocarbon migration distance, including a multi-sourced area model and a single-sourced area model. In addition, the accumulation models could be also classified into near source accumulation and far source accumulation based on the lateral hydrocarbons migration distance.
