【摘要】 本文运用物质平衡及渗流力学原理,提出一种气顶和溶解气综合驱动油藏的动态预测计算方法,并编制了工程软件。应用该软件对油藏在压降条件下的综合指标进行预测,也可以计算储量和气顶大小。实例计算表明,气顶大小对原油采收率有着重要的影响。更多还原

【Abstract】 This paper presents a method for predicting reservoir performance with gas cap and solution gas drive. A computation procedure is proposed by simultaneous solution of material balance equation and multiphase flow equation.An engineering computer program was developed to predict the production parameters of the reservoir under decreasing formation pressure and also to evaluate the oil reserves. The computation result showed that the gas cap volume had a significant influence on the recovery factor of oil reservoir.更多还原
