The fore-bulge of the Northern Tarim Basin is the most important exploration area of the marine craton. In this area, enriched petroleum sources and multilayered reservoirs have been determined to be developed. The hydrocarbon phases are quite diversified and complex, and include condensates, normal oils, heavy oils, and dry asphalt. According to the systematic analysis of the formation, evolution, and conservation of the marine reservoirs in the fore-bulge of the Northern Tarim Basin, as well as the geochemistry characteristics of the petroleum and fluid inclusions, it is believed that the Ordovician marine reservoirs in the eastern fore-bulge experienced three important hydrocarbons charging stages.
