Numerical Simulation of Water Control Technology in Deep Water Gas Reservoir

Abstract

Abstract In recent years, large deep-water gas fields such as Yacheng and Lingshen have been discovered successively in deep-water exploration in the South China Sea, with huge reserves. However, bottom water is ubiquitous in deep-water gas fields, which seriously affects gas reservoir recovery. Therefore, it is beneficial to improve the development effect of gas reservoirs to clarify the water invasion mechanism and law of bottom water gas reservoirs. Based on the study of water invasion law of deep water gas reservoir, the development effect of deep water gas reservoir under different water control technology conditions is evaluated by numerical simulation method in this paper. It provides a strong basis for rational and effective development of deep-water gas reservoirs and water control and waterproofing technology.
