摘要
东营盆地已发现和探明油、气藏的分布规律性很强。气藏的分布从盆地内部到边缘分为3个环形带,即溶解气带、气顶气带和气层气带。油藏的分布则分为4个不同含油层系的环状带,即沙--沙二段油藏带、沙三段油藏带、沙三-沙四段油藏带和东营-馆陶组油藏带(稠油带)。油、气藏这种分布规律既受由盆地中心向边缘挤压型水动力系统的控制,也受油、气藏所在构造部位的温度、压力等因素的影响。
The distribution of discovered and proved oil and gas pool in Dongying basin has a very significant regularity.The gas pool distribution is distributed in three ringlike zones from the certer to the margin of the basin.Namely dissolved gas zone,gas-cap gas zone,and gas reservoir respectively oil pools are in four ringlike zones.They are s_1-s_2 oil pool zone,s_3 oil pool zone s_3-s_4 oil pool zone and the Dongying formation to Guantao formation oil pool zone (thick oil zone), Such a distribution of oil and gas pool is mainly controlled by compressi- onal hydrodynamic systems from the center to the margin of the basin and by the temperature and the pressure of their structural settings as well.
