窄河道型油田油井见水时间研究

摘要：见水时间是描述油田注水效果最为重要的参数之一，是油田开发设计的重要指标。然而，对于条带状窄河道型油田油井见注入水时间研究尚未见到报道。窄河道型油田油井的见水时间究竟与哪些因素有关一直是油藏工程师关注的重要问题。本文根据渗流理论，推导出窄河道型油田见水时间公式，并与渤海B油田的实际油井见水时间进行对比，相对误差很小，准确度很高。本文的结果对窄河道型油田注水开发中的实际应用提供了理论基础。

A Theoretical Calculation Formulae Of Water Breakthrough Time In Narrow Channel Sand Reservoir

Abstract: One of the most important parameters, describing the effect of water injection, is water breakthrough time, and it is an important index in oilfield development. However, the water breakthrough time in narrow channel sand reservoir has not been studied, and it is necessary to be further studied. Reservoir engineer has always interested in the factors that affect the water breakthrough time in the narrow channel sand reservoir. Based on the theories of percolation flow mechanism, the water breakthrough time in narrow channel sand reservoir is studied, and the theoretical calculation formulae of water breakthrough is derived. Filed applications show that the relative error between practical and calculated value is less, and the calculation result is accurate. The results of this paper can provide the theoretical basis for the practical application of water injection in narrow channel sand reservoir.
