| 摘 要： | 在Ozkan ＆ Raghavan的均匀流率水平井解析模型基础上,建立非均匀流率无限导流的水平井计算模型,利用离散化数值求解技术,以半解析方式计算获得水平井的不稳态流率分布和井筒压力.计算表明,无限导流水平井压力动态早期受流率分布变化影响,并不出现井筒径向流特征.该计算模型具有灵活的扩展机制,为水平井的完井方案优选、产能预测提供了快速、灵活的分析工具.

| Abstract: | Based on uniform flux analytic model of Ozkan and Raghavan,this paper establishes a computational model of infinite-conductivity horizontal well transient pressure,with discrete numerical method and semi-analytic to calculate transient flux distribution and well- bore pressure.The results indicate that infinite-conductivity horizontal well transient pressure is influenced by variable flux,but it doesn't appear early well-bore radial flow characteristic.The method has flexible extend mechanism and is a fast tool for completed well optimization and inflow performance forecast. |
