【摘要】 地层中油气水的分布受储层性质、构造位置及压力系统等多种因素的影响。单一的随机建模方法不能准确模拟储层含水饱和度的分布,必须根据油气水分布的主要控制因素,制定有效的约束条件,才能建立准确的含水饱和度分布模型。根据长岭气田营城组火山岩气藏自身的特点,以地震多属性反演预测的含水饱和度数据体做为约束条件,建立了适合该地区流体分布规律的含水饱和度分布模型。更多还原

【Abstract】 The distribution of oil,gas and water in the formation was controlled by reservoir property,location of structure and pressure system,and so on.Building the water saturation distribution model with stochastic method could not accurately simulate the distribution of water saturation in the Formation,the valid constraining condition should be established according to the main controlling factors.On the basis of the volcanic reservoir characteristics of Yingcheng Formation in Changling Gas Field,the seismic multi-property inverted water saturation is used as constraining condition,and the water saturation distribution model is fit to the fluids distribution law.更多还原
