【摘要】 大庆升平气田为深层裂缝性火山岩气藏,由于开发井少,对地质情况了解不是很清楚。如何根据现有的地质资料建立地质模型是气藏数值模拟的关键。根据地震相干体,预测出裂缝的分布,引入等效介质理论,建立了地质模型。利用Eclipse软件中的VFPi模块,将井底流压折算成井口的压力,并对SS2和SS1 2口生产井进行井口压力的历史拟合。在历史拟合的基础上,进行了井网的优选和采气速度的优选,并对方案进行了预测。从已钻几口井的试气试采情况看,和预测结果比较吻合。更多还原

【Abstract】 Shengping gas-field in Daqing is volcanic gas reservoir with fractures and deep thickness.Due to shortage of producing wells,geologic information cannot be known well.It is the key for numerical simulation that how to establish geologic model based on current documents.According to seismic coherent body,this paper predicts distribution of fractures,uses equivalent medium theory,and establishes geologic model.With VFPi modular of Eclipse software,it converts flow pressure of bottom hole into well head pressure,and performs history matching of well head pressure of Well SS2 and SS1.On the basis of matching,it optimizes well pattern and velocity of gas production,and predicts the project.Production test and gas test coincident with predicted results.更多还原
