摘要
为了正确使用系统试井资料 ,对用指示曲线确定油井采油指数和油藏地层压力的理论方法进行了研究 ,得出如下结论 :对于注水保持压力开采的油藏 ,油井泄油范围的外边界压力为一常数、泄油范围内的平均地层压力为一变量 ,应用指示曲线只能确定油井泄油范围的外边界压力Pe 和以Pe 定义的油井采油指数Jo(Pe) ;而对于衰竭开采的油藏 ,油井泄油范围内的平均地层压力为一常数、泄油范围的外边界压力为一变量 ,应用指示曲线则只能确定油井泄油范围内的平均地层压力 P和以 P定义的油井采油指数Jo( P)
In order to use well test information correctly, a theoretical study was conducted on the determination of productivity index (PI) and formation pressure from IPR curves. For pressure-maintaining reservoir, because the external boundary pressure (P e) keeps constant and the average pressure is a variable over the drainage area of the well, only P e and the productivity index J o(P e) of an oil well defined by P e can be obtained from IPR curve. For depleting reservoir, because P e is a variable and the average pressure over the drainage are a keeps constant, only and the productivity index J o() of an oil well defined by can be obtained from IPR curve.
