Abstract

To address the problems of unidentified characteristics of the hydrocarbon transmission system and unclear direction of on-scale reserve stimulation and exploration of hydrocarbon transmission system in Buried Hills, West Sag, Laiohe Depression, the buried hill in West Sag were classified as intra-source, source-edge and extra-source types by the analysis method of tectonic characteristics and evolutionary history, the studies on typical buried hill reservoirs, and the contact relationship between buried hills and mature source rocks, and hydrocarbon transmission model of different types of buried hills was established. The study results showed that, the intra-source buried hills in West Sag were developed with complex hydrocarbon transmission conditions, such as fractured reservoir, fault and nonconformity, and the transmission system was the most favorable, with weathered crust and internal reservoirs developed; source-edge buried hills were laterally developed with fault plane or unconformity as main transmission channel; the hydrocarbon content and amplitude of the buried hill were controlled by the size of oil supply window and the development degree of buried hill reservoir; in extra-source buried hills, source-connected fault served as hydrocarbon migration channel while the unconformity served as the horizontal migration channel, and weathered-crust buried hill reservoir was mainly developed. The results of the study are of great significance to the next exploration trend and the selection of favorable targets in the buried hills in West Sag.

Key words： buried hill; migration system; intra-source type; source-edge type; extra-source type; Liahe Depression
