| description | Gas Hure Oilfield is an area rich in oil and gas in the Qaidam Basin and contains E31 and N1-N21 oil reservoirs. Through conventional column chromatographic extraction of 48 oil samples, this paper investigates the oil migration and charge direction using nitrogen compounds, sandbody distribution in E31 and N1-N21, and the E31 reservoir dissection. Oil in the I+II and III+IV oil layers of the E31 reservoir migrates from the middle-north of the anticline to its south and north, and its oil source areas are the Mangya hollow and the Gas rift-subsidence. The injection spots of the III+IV oil layer are the two sides of well 9-7 in the middle of the anticline, and the injection spots of the ?+? oil layer are wells 8-34 and 9-38. The N1-N21 reservoir oil is mainly from the Mangya hollow and migrates upwards along faults to reservoirs. Faults and sandbodies are the main transport channels in the field and most reservoirs are anticlinal. Key words: Qaidam Basin, Gas Hure Oilfield, nitrogen compound, crude oil, migration |
