Abstract Muyuan sag, with low exploration and research degree, has no great progress in petroleum exploration. Therefore, field geological survey, re-examination on old wells and organic geochemistry work were performed to investigate the oil and gas potential and exploration prospects. The petroleum geological condition was analyzed: ①Muyuan sag has dustpan-like feature with single fault and the sag consists of three structure zones—abrupt slope zone, deep sag zone and gentle gradient zone. ②Three effective source rocks, Damoguaihe Formation, Nantun Formation and Xing’anling Group, were developed. Nantun Formation and Damoguaihe Formation deposited thickly, distributed widely and maturated well with good organic type (II₁-I). These two formations also have high organic abundance, superior hydrocarbon generation potential with mature thermal evolution and they are major source rocks in the basin. Xing’ anling Group has high organic abundance and are in high-over maturity, with limited thickness and distribution, but it is still valuable source rocks. ③There exist three source-reservoir-cap rock associations in the basin, which are the self-source and self-reservoir or the upper-source and lower-reservoir type of Xing’ anling Group, the self-source and self-reservoir type of Nantun Formation and Damoguaihe Formation, the lower-source and upper-reservoir type of Yimin Formation. Compared with the reservoir formation law of dustpan-like feature with single fault in high-exploration area, combined with the geological characters in Muyuan sag, the hydrocarbon accumulation pattern was established. Based on the primary play assessment, two favorable exploration areas and targets were proposed.

Key words： Hailaer Basin structural feature source rock character accumulation pattern play assessment
