一种新井部署矿场可实施性的定量评判方法及其在XX油田的应用

A quantitative evaluation method for field implementation of new well deployment and its application in XX oilfield

为了降低稀油水驱老油田新井部署矿场实施的风险,改善新井投产效果,在井网控制分析的基础上,通过油藏工程计算,提出了一种新井部署矿场可实施性的定量评判方法。该方法主要包括井区的新井控制可采储量政策界限、原始地质储量、综合含水、采出程度及最终可采储量等五个关键量的计算,并通过比较最终可采储量与新井控制可采储量政策界限的大小,来定量评判其矿场是否具有可实施性:即最终可采储量不小于新井控制可采储量政策界限,则矿场可实施,否则矿场不可实施。该方法经矿场实施验证,评价成功率为91.6%,准确性较高。

In order to reduce the risk of field implementation of new well deployment and improve the production effect of new wells,a quantitative evaluation method of field implementation of new well deployment is proposed based on well pattern control analysis and reservoir engineering calculation.The method mainly includes the calculation of five key quantities,such as the policy limit of new well controlled recoverable reserves,original geological reserves,comprehensive water cut,recovery degree and final recoverable reserves.By comparing the ultimate recoverable reserves and the policy limits of controlling recoverable reserves of new wells,the field implementation can be evaluated quantitatively.When the ultimate recoverable reserve is greater than or equal to the policy limit of new well controlled recoverable reserves,the field can be implemented,otherwise,it cannot be implemented.Through application,the method has been verified and the success rate of evaluation is 91.6%,with higher accuracy.
