摘要(Abstract)：
针对大庆长垣外围油田构造复杂、断层密集、储层横向变化大的特点 ,在地震构造解释和属性分析的基础上 ,采用能够协同地震变量的具有外部漂移的克里金方法建立储层地质模型。在宋芳屯油田芳 2试验区块的应用结果表明 ,构造模型的深度误差小于 0 1% ,砂岩模型的符合率达到 86 %以上。该建模方法对于大庆长垣外围油田精细油藏描述具有重要的意义。
Aimed at the characteristics of complexity structure of peripheral oilfields in Daqing placanticline,dense faults and horizontal great changing of the reservoirs,based on seismic structural interpretation and attribute analysis,Kriging method,which could synergist seismic variation,with outside drift is adopted to set up reservoir geological model.Application result of the research achievement in Fang 2 pilot area of Songfangtun oilfield shows that depth error of the structural model is less than 0.1% and coincidence rate of sandstone model reaches more than 86%.This reflects the model has an important sense in fine reservoir description of peripheral oilfields in Daqing placanticline.
