摘要

江汉盆地丫角低凸起潜江组生油岩尚未成熟。丫角油田原油与清水口洼陷潜江组原油不同源

而可能来自潜江凹陷高场、浩西一带的潜3、4段。

Abstract

Yajiao oilfield is located between Qianjiang Depression and Jiangling De-pression of Jianghan Basin in central China.The oil is produced in the Qian-jiang Formation of the Eogene.Its specific gravity is more than 0.91

visco-sity more than 0.1Pa.s

sulphur content greater than 1%

saturated hydrocarbon content less than 38%.According to biomarker and other geological-geochemicaldata

it is inferred that the oil is derived from the Qianjiang Formation of Qianjiang Depression instead of Jiangling Depression.
