自1956年Park Jones提出利用压力恢复曲线确定单井控制地质储量方法之后,近20年来,这方面的理论研究和方法应用都有较大的进展。但是,直到目前为止,利用压力恢复曲线确定地质储量的各种方法,都是把油井周围的边界形状看成是圆形的。但实际上油井周围的边界形状和油井所处的位置是多种多样的。因而,不考虑实际情况,均当作圆形边界处理,必然会引起相当的误差。
Since 1956, Park Jones proposed the use of pressure recovery curve to determine the method of single-well control of geological reserves. In the past 20 years, there has been great progress in theoretical research and application of this method. However, until now, various methods of determining the amount of geological reserves using pressure-recovery curves have seen the shape of the boundary around the well as being circular. But in fact the shape of the boundary around the well and the location of the well are varied. Therefore, irrespective of the actual situation, all of them are treated as circular boundaries and inevitably cause considerable errors.
