单井控制面积权衡储量计算中控制面积的确定

Determination of Well Spacing in Reserve Estimation by Well Spacing Weighting Method

采用单井控制面积权衡方法可以计算油藏的储量．该方法认为观测数据的权值与观测点的疏密有关：在观测点密集的地方，观测数据的权值较小，而观测点稀疏的地方，观测数据的权值则较大．其关键是如何计算每个观测数据的权值．通常这个权值定义为观测点控制区域的面积．该方法的特点是可以把一个任意复杂的边界分解成若干个简单的边界问题来处理，从而可计算复杂构造油藏的储量．该算法已在微机上实现，并投入生产．

he reserve volume of the reservoir can be estimated by using the well spacing weighting method. This method holds that the weighted value of the observed data has something to do with the density of the observing spots: where the observing spots are more,the weighted value of the observed data is small;where the observing spots are fewer.the weighted value of the observed data is great. The key problem is how to calculate the weighted value of each observed data. The weighted value is usually defined as the space of the area controlled by the observing spots. This method is characterized by resolving the complex boundary problem into several simple problems to be solved. In this way,the reserve of a reservoir having complex structure can be calculated. This method has been realized on the computer and has been applied in oil production.
