Research and Application of Intelligent Gel Chemical Sand Protection System in Sand Producing Gas Wells

Abstract

The reservoir of a loose sandstone gas field has the characteristics of high clay, high mud, high mineralization, easy water invasion, etc. Sand production greatly limits the utilization of production capacity and the application of many drainage and mining technologies. Therefore, a simple construction and the cost is low and it can effectively control the problem of fine sand production which is difficult to be solved by mechanical sand control. based on the idea of coordinated water management, an intelligent gel chemical sand control system was developed through indoor experimental performance evaluation methods and applied in A The well was successfully applied. After the measures were taken, the well resumed production and its daily gas production capacity was better than the level before the well was shut down. The results show that the technology can significantly reduce the above research provides an effective solution for preventing and controlling the blockage of mud and sand particle migration in loose sandstone gas fields.
