摘要
时移地震技术能否成功预测海上油田剩余油分布情况,靶区的选取十分重要。以珠江口盆地西江24-3油田西江24-1区为例,详细阐述了时移地震技术在我国海上油田的应用情况及效果,并通过对比已有的几个应用案例,总结了时移地震技术应用的关键因素,制定了靶区选取原则。我国海上油田时移地震技术成功应用的首要关键因素是原油黏度,其次是开发方式和埋深、构造及储层等;靶区油田应具备轻质油藏、天然能量或温和注水开发及相对简单的地质油藏条件。在此基础上,对我国海上油田时移地震技术应用前景进行了展望,认为渤海新近系油田时移地震技术应用有待进一步深入研究,珠江口盆地和莺琼盆地应用该技术的可行性较好。
The target selection for time-lapse seismic technology has a significant impact on successfully forecasting remaining oil distribution in offshore oilfield. By taking Xijiang 24-1 block of Xijiang 24-3 oilfield in the Pearl River Mouth basin as an example, the application and effect of time-lapse seismic technology in China offshore oilfield is elaborated. The key factors of timeqapse seismic technology application are summarized and a principle of target oilfield selection is developed by comparing applica- tion cases. The primary key factor is oil viscosity, followed by development mode, depth, structure and reservoir, etc. The target oilfield should be light oil reservoir, developed by natural energy or mild water flooding and relatively simple geological and reservoir conditions. Based on the research, the application of time-lapse seismic technology in China offshore oilfields is prospected. Results show that the application in Neogene oilfield in the Bohai sea needs further study and it is feasible in the Pearl River Mouth basin and the Yingqiong basin.
