准噶尔盆地春光油田油气充注史

ynamic of hydrocarbon accumulation mechanism and gas filling history is one of the hot spots in the petroleum geology in recent years. Compared with the traditional heavy oil producing area, Chunguang oilfield As a light oil producing areas, that has been found lately in Junggar basin is quite different on accumulation process. Because many sets of production layers (K, E, N) was developed in Chunguang oilfield, we collected samples from 11 wells. Microscopic observations showed that the oil inclusions have high maturity (fluorescent color is blue and white) in Chunguang area. At the same time, the homogenization temperature of fluid inclusions showed different hydrocarbon filling history. The petroleum accumulation stage of The Neogene Shawan Formation is about 5-8Ma. Meanwhile, although homogenization temperatures of fluid inclusions from Paleogene and Cretaceous bedsindicate the in an oil and gas filling process, but the biomarkers of the oil reflected a typical early oxidation with late oil mixed .
