辽河油田多样油品成因探讨

Discussion on Causes of Crude Oil Variety in Liaohe Oilfield

辽河油田是渤海湾油气区的重要组成部分,地质结构复杂,断层异常发育,为典型的断块油田。同时具有多套油气层,多种油气藏类型。对辽河油田油品多样性进行了论述,对油藏埋深、地层水、运移距离以及盖层条件对油藏原油性质影响进行了探讨,提出造成辽河油区油品多样化的重要影响因素。

Liaohe oilfield is an important part of Bohai Gulf oil and gas area, has complex geological structure and fault abnormal development, and belongs to typical fault block oilfields. Liaohe oilfield has multiple sets of hydrocarbon formations, various types of oil and gas reservoirs. In this paper, the diversity of crude oil in Liaohe oilfield was discussed, effect of reservoir buried depth, formation water, transport distance and caprock conditions on properties of crude oil was investigated, the important factors to cause the diversity of Liaohe crude oil were put forward.
