摘　　要：丘东气田三间房组上段为辫状河三角洲前缘末端沉积,砂体厚度薄,横向变化快,非均质性强,储层精确识别和横向预测存在诸多困难。研究采用确定性建模和随机建模相结合的方法,以井震结合精细地层格架和测井相解释成果为依据,在地震体约束下,综合利用多种资料,建立了三间房组上段三维精细地质模型,为下一步气田合理开发调整提供了有利的地质基础。The gas reservoir of the upper segment of Sanjianfang Formation in Qiudong Oilfield belongs to braided stream delta front deposits. Because of thin sandbody, rapid lateral change, and strong reservoir heterogeneity, there are many difficulties in accurate identification and lateral prediction. By combining the deterministic modeling with the stochas- tic modeling, a 3 D fine geologic model for the upper segment of Sanjianfang Formation under the constraint of seismic body was established according to the analysis of log facies and the fine stratigraphic framework combined with borehole - seism. Finally,it provides a favorable geological basis for the reasonable development and adjustment of gasfield.
