摘要
利用容积法计算五点法井网井组的地质储量,采用传统方法或已有的方法确定井组的含油面积时效率不高。根据五点法井网井组边界的特征,首先定义了内部井、边井和角井,并提出了相应的判断方法。然后根据井组储量计算原理,确定了内部井不需要外扩,边井和角井需要外扩的原则。最后通过五点法井网井组的组合方式,提出了边井和角井的外扩算法,形成了五点法井网井组边界的自动确定方法。该方法能够自动、快速、准确地确定五点法井网井组的边界,进而确定井组的含油面积。
For geological reserves＇ calculation of five-spot well pattern,it is not high-efficiency to use volumetric method.Meanwhile,by using traditional or existing methods,it is difficult to determine oil-bearing area.Firstly,according to the characteristics of well pair borderline of five-spot well pattern,the interior well,edge well and corner well are defined as well as put forward the corresponding judging method.Then,with the reserve calculation principle,it was certain that the interior wells need not extending while edge wells and corner wells need extending.Finally,through the combination mode of five-spot well pattern,the extension algorithm of edge well and corner well was put forward and the automatic determination method of well pair borderline of five-spot well pattern was formed.Therefore,such method can determine well pair borderline of five-spot well pattern automatically,quickly and accurately,which can further determine oil-bearing area.
