古三角洲砂体入湖距离的动力学预测

在油气勘探储层预测工作中,常规相分析法得到了普遍的应用,地震地层学方法也正引起人们的重视。但是,前者主要是定性分析,并在勘探程度较高时才能做到。后者对地震工作提出了严格的要求,并需一套相应的处理技术。而砂岩储层的动力学预测可在不同的条件下进行,实际上迫切需要对储层分布作出预测的时候,往往正是勘探程度较低而又缺乏高精度、高密度地震资料的时候。因此,在油气勘探中,储层分布的动力学预测可以发挥独到的作用。

DYNAMIC CALCULATION OF THE DISTANCE OF ANCIENT DELTAIC SANDBODY ENTERING INTO LAKE

To calculate the distance between an ancient river mouth and the area where the deltaic sandbody enters into an ancient lake, the dynamic calculative method can obtain quantitative or semi-quantitative results compared with sedimentary fa-cies analyses. Sometimes, it is easier to get the required information without complex treatment as compared with seismic stratigraphic analyses. So the dynamic calculative method cannot be replaced by other.
