中文摘要：

油田注水井井下分层注水量的调配工作传统上都是通过钢丝绳作业采用“试凑法”反复测调来实现，为解决传统方法存在的问题提出了一种理论方法用于指导注水井分层调配，可以大幅度降低测调工作强度，缩短施工时间，提高配注精度，提高注水井分层测调效率。注水井分层注入涉及到复杂的流体力学计算，整个过程是一个井筒管流、水嘴节流与地层渗流的耦合流动。在井筒采用柏努利方程描述井简管流，采用Navi.Stocks（简称N-S）方程计算水嘴节流，以均质无限大地层为例计算地层渗流，得出了在不同水嘴尺寸下的各层流量衰减规律，为注水井分层流量调配提供了科学依据。

英文摘要：

The adjustment of respective layer flow rate in injection wells is realized conventionally by repetitious measurements of cut-and-try method during wireline operation. Herein this article, a new theory has been proposed in reference to the respective layer flow rate adjustment and solve the problems in conventional methods, according to and through which, the measuring workload could be greatly reduced, operation time could be shortened, the injection proration preciseness could be enhanced and the measuring efficiency could be promoted. The respective layer injection involves with complicated fluid dynamics computation, the whole process of which is actually the coupling flowing process of wellbore pipe-flow, throttled flow and stratum filtering flow. Bernoulli Equation is adopted to describe wellbore pipe-flow and Navi-Stocks equation is used to calculate the throttled flow, while the computation of stratum filtering flow is under homogeneous infinite formation conditions, as a result, the declination rules of respective layers under water nozzles of different sizes are concluded, which could be support the adjustment of respective layer flow rate in injection wells.
