本文提出了一种用于预测井下压力的集成多相流模型。该模型的目的是在保持简单形式的情况下，在广泛的流动条件下产生更准确的井下压力预测。作为集成模型的一个组成部分，提出了一种改进的分离流双流体模型。将双流体分离模型的结果与五种最先进的现有模型进行了比较，将集成模型的结果与三种模型进行了比较。

介绍

在井的整个寿命期间，了解井底流压（P wf）和井筒压力分布具有重要意义。

Integrated Multiphase-Flow Modeling Technique Yields Accurate Downhole Pressure Predictions

This work presents an integrated multiphase flow model for downhole pressure predictions that produces relatively more-accurate downhole pressure predictions under wide flowing conditions while maintaining a simple form.

This work presents an integrated multiphase flow model for downhole pressure predictions. The aim of the model is to produce more-accurate downhole pressure predictions under wide flowing conditions while maintaining a simple form. As a component of the integrated model, an improved two-fluid model for segregated flow is proposed. Results of the two-fluid segregated model are compared with five state-of-the-art existing models, while results of the integrated model are compared with three models.

Introduction

Throughout the life of the well, knowing bottomhole flowing pressure (Pwf) and the pressure profile of the wellbore are of great significance.
