| 摘 要： | 对钻井资料较少的莺歌海盆地某气田采用流体相控属性建模,利用叠前纵横波速度比反演预测储层含气性和储层测井综合解释成果,用随机模拟方法建立储层的流体相模型;用流体相模型进行间接相控,建立了用波阻抗约束的随机模拟孔隙度模型,解决了浅层气藏由于受含气效应影响导致模拟的气层孔隙度偏高而难以正确反映储层物性分布的问题。在此基础上求得连通因子平面分布,勾出孔隙度分隔带,解释了研究区压力和气体类型分区特征。

| Abstract: | A reservoir model is built with the fluid facies-controlled property parameters for few available drill data of a shallow gas field in Yinggehai basin. Using the results of the seismic fluid inversion of P/S waves ratio before stack and the logging interpretation, a fluidfacies-controlled model is done by stochastic reservoir modeling and then under the fluidfacies model, a porosity parameter model with varying wave impedanc is stimulated, which can solve the problem that the distribution of reservoir properties is unable to stimulate rightly with the common method due to likely high porosity in gas-bearing beds. Based on the porosity model, connectivity factors are calculated and inner boundaries of reservoir porosity are described. This result has interpreted the distribution characters of pressure and gas types in study area. |
