Advances in Gas Well Fluid Accumulation Modeling

Abstract

Liquid accumulation at the bottom of a well is an important cause of production reduction or even shutdown of natural gas wells, and it is inevitable that water-bearing formations generate liquid accumulation when producing natural gas. Therefore, it is important to study gas well liquid accumulation models and identify liquid accumulation at the bottom of a well in order to take timely and reasonable process measures to deal with liquid accumulation at the well. Based on this, this paper analyzes the current status of domestic and international research on gas well critical fluid-carrying droplet models and critical fluid-carrying film models through literature research, analyzes the problems and development trends of research on gas well fluid accumulation prediction, and provides a comprehensive and systematic summary of the progress of gas well fluid accumulation model research.
