【摘要】 以高尚堡油田高104-5区块馆陶组8#小层水平井开发油藏为例,分析水平井钻井资料、地震资料等各种基础信息的地质意义并加以综合利用,在单砂体内部开展沉积旋回精细划分对比的基础上,采用目前流行的相控随机建模技术建立了水平井目的层单一目标砂体高精度地质模型。在此基础上,开展精细油藏数值模拟研究,建立油藏动态模型,进而通过历史拟合以及动态方法对静态模型进行验证,经验证,所建立的地质模型具有较高的精确度,能够满足进一步开展研究工作的需要,并以此为基础对水平井开发状况、含水特征、见水规律以及剩余油分布特征等问题进行研究和评价。图11参10更多还原

【Abstract】 The horizontal well-produced oil reservoir was taken as an example in No.8 substratum of the Guantao Formation,block Gao 104-5,Gaoshangpu Oilfield.Horizontal well drilling data,seismic data and other fundamental information,combined with the fine internal division and correlation of sedimentary cycles in a single sandbody,were used to establish a single-sandbody high-precision geological model for the target zone of horizontal well,with the currently popular phased stochastic modeling technology.On this basis,we carried out detailed reservoir numerical simulation and established a dynamic reservoir model,then verified the static model with history matching and dynamic method.The geological model has high accuracy,and meets the demand of further research.With the modified model,we researched and evaluated the development status of the horizontal wells,the characteristics and trend of water cut and the distribution characteristics of remaining oil.更多还原
