Keywords:
Because of the typical tight oil reservoir developing in Fuyu reservoir in northern Songliao Basin; horizontal well can be used for increasing production; and improving the efficiency and the rate of using.However; the accuracy of prediction for multilayer superimposed sand body is the most important factor of determining the success or failure of the horizontal well development and drilling.So the seismic response characteristics can be simplified; and the amplitude influence of each single sand layer was also cleared by the sand removal test.Then it was implemented the geological model designing; forward modeling; amplitude recovering; the channel sand body identification and the reservoir prediction for the different sand combination.By the practical application; it showed that there was a high alignment between the drilling result and the seismic predicton.

摘要:
松辽盆地北部扶余油层发育典型的致密砂岩油储层,需要通过水平井提产增效,提高动用率。多层叠置砂体储层预测的准确性,是决定水平井部署和钻探成败的最主要因素。为此,利用去砂实验简化地震响应特征,明确各单砂层对振幅的影响。在此基础上,设计地质模型,进行正演模拟,建立振幅恢复方法,在平面上刻画河道砂体的分布,对不同组合砂体进行储层预测。经实际应用证实,钻探结果与地震预测吻合度较高。
Abstract:
Because of the typical tight oil reservoir developing in Fuyu reservoir in northern Songliao Basin,horizontal well can be used for increasing production,and improving the efficiency and the rate of using.However,the accuracy of prediction for multilayer superimposed sand body is the most important factor of determining the success or failure of the horizontal well development and drilling.So the seismic response characteristics can be simplified,and the amplitude influence of each single sand layer was also cleared by the sand removal test.Then it was implemented the geological model designing,forward modeling,amplitude recovering,the channel sand body identification and the reservoir prediction for the different sand combination.By the practical application,it showed that there was a high alignment between the drilling result and the seismic predicton.
