| description | With the successful development of unconventional hydrocarbons, the production of unconventional hydrocarbons has increased rapidly. However, a single conventional or unconventional model is not suitable for the mechanism of hydrocarbon accumulation in a given basin or sag. Based on data from drilling, logging, and geophysical analysis, the hydrocarbon accumulation mechanism in the Hari sag in the Yingen-Ejinaqi basin, China, was analyzed. There are three sets of source rocks in the Hari sag: the K<sub>1</sub>y source rocks were evaluated as having excellent source rock potential with low thermal maturity and kerogen Type I-II<sub>1</sub>; the K<sub>1</sub>b<sup>2</sup> source rocks were evaluated as having good source rock potential with mature to highly mature stages and kerogen Type II<sub>1</sub>-II<sub>2</sub>; and the K<sub>1</sub>b<sup>1</sup> source rocks were evaluated as having moderate source rock potential with mature to highly mature stages and kerogen Type II<sub>1</sub>-II<sub>2</sub>. Reservoir types were found to be conventional sand reservoirs, unconventional carbonate-shale reservoirs, and volcanic rock reservoirs. There were two sets of fault-lithologic traps in the Hari sag, which conform to the intra-source continuous hydrocarbon accumulation model and the approaching-source discontinuous hydrocarbon accumulation model. The conclusions of this research provide guidance for exploring multi-type reservoirs and multi-type hydrocarbon accumulation models. |
