BASIN FORMATION MECHANICS AND HYDROCARBON POTENTIAL EVALUATION OF XINGANLING BASIN GROUP

In order to enlarge the field of oil and gas exploration and seek more resources, this paper analyzes the geodynamic condition and basin formation mechanics of Xinganling basin group. It uses geochamical indexes to evaluate qualitatively the hydrocarbon potential of the basins and indicates that this basin group has experienced 3 periods of large structural movement, forming relatively 3 basin formation periods. Comprehensive analysis shows that upper Jurassic Mesozoic in each basin has a nice hydrocarbon condition. Station 22 and Emuerhe Member in Mohe Basin, Taipinglinchang Member in Sunwu jiayin Basin, Damoguaihe Member in Labudalin Basin and Jiufengshan Member in Dayangshu Basin are the favorable horizons of next exploration.
