摘要: 根据原油物性和地化分析资料将陆南凸起的原油分为五类:夏盐型—成熟一高成熟的古生界原油;石西型—高成熟的古生界原油;陆南型—成熟的中生界与古生界混源原油;滴西型—成熟的中生界原油;滴南型—低成熟-成熟的古生界原油。根据各类原油在平面上的分布规律,结合构造圈闭条件,预测出三个含油气有利区,其中陆梁隆起西段和达巴松凸起是勘探相对成熟区;东道海子北凹陷至五彩湾凹陷一带之东侧是寻找古生界自生自储油气藏的有利地区,而凹陷边缘隆起区是寻找断裂遮挡型油气藏的有利地区。

Abstract: Oils from Lunan arch are classified into five types, namely, Xiayan type- -mature to highly mature Paleozoic oils, Shixi type- -highly mature Paleozoic oils, Lunan type- mature Mesozoic and Paleozoic mixed oils, Dixi type- mature Mesoozoic oils, and Dinan type- -low mature to mature Paleozoic oils, based on the physical properties and geochemical data of oils. According to the regular distribution of different oil types in section, along with the trap conditions, three favorable hydrocarbon-bearing zones are circled out. The west part of luliang uplift and Dabasong arch are the moderately. explored areas, the area from north Dongdaohaizi sag to the east side of Wucaiwan sag is the favorable target for Paleozoic self-sourced, self-storaged reservoir, and in the uplift zone at the sag margin it is highly probable to find the fault-screened oil and gas reservoirs.
