在前人提出的中心管完井控锥基础上,针对水平井高含水情况,扩展了中心管完井的思路,提出中心管采油的概念.根据线汇叠加、镜像反映以及质量守恒和动量原理推导得到中心管耦合模型,利用模型计算了实例的流入剖面,对比中心管施工前后流入剖面,通过方案优选给出中心管施工推荐方案.现场施工一个多月后,采油量上升,含水率下降,达到了明显的增油降水效果,同时证明了采用中心管来调节油井高含水期生产指标是可行的.

This study suggests the concept of Stinger Prouduction which can solve higher water cut in horizontal wells based on Stinger Completion. Stinger coupling model can be achieved by liner superimpose and reflection mirror principle and mass conversa-tion and momentum principle. Example's influx profile is computed by the model. So you can tell the influx profile difference between before stinger construction and after. The final stigner construction plan can be got through optimization. After about one month, oil production increased and water cut declined which suggests that it's possible to adjust production quota at the time of higer water cut by using stinger.
