摘要
///The assessment of oil connectivity makes up an indispensable part of the field production and field management scheme, in which the oil chromatographic fingerprint technology can play an important role. Studies of oil chromatographic fingerprint for the Mesozoic oil reservoir connectivity of the Ordos Basin in southern Anbian-Dingbian area show that there exist significant differences in the fingerprint distribution between Tiebiancheng, Dingbian, Jiyuan, and Hujianshan well fields, suggesting that fluids in reservoirs of these well fields are not connected with each other.In the studied area, the differences in oil chromatographic fingerprint distribution between Yanchang Formation and Yan’an Formation reservoirs are probably caused by the migration of oil and gas, and are closely related to the heterogeneity of the ancient geographic location.
