油田注水开发期含水率随时间变化规律研究
|
摘要
含水率预测是油藏工程研究的重要组成部分。目前的含水率预测一般只能建立含水率与采出程度的关系,而油田工作者往往希望直接得出含水率随时间变化的规律。以水驱特征曲线方程为基础,分别结合以Arps与Logistic为代表的产量递减方程和以瑞利模型为代表的产量变化全过程预测模型,推导出了油田产量遵循不同变化规律时含水率随时间变化的关系式,为油田动态和稳产形势分析,开发方案编制以及技术对策调控均提供了可靠的理论依据。
Predicting water cut is an important part of reservoir engineering study. At present, we can only establish the relationship between water cut and production level for the water cut prediction, but the oilfield workers often want to get the water cut change law with the time of oilfield development. Based on waterflooding characteristic curve equation,combined with Arps and Logistic production decline equation and Rayleigh model for production change whole process respectively, the relation formula between water cut and time was derived when the oilfield production follows different change law. This change law can provide a reliable theoretical basis for the analyses of the dynamic and stable situation of oilfield, the establishment of development plan and the control of technical countermeasure.
