Optimization of management measures for water-producing gas wells in SM gas field

Abstract

SM gas field is a typical tight sandstone gas reservoir, which adopts the production mode of downhole throttling and inter-well series connection. Gas wells will have different production characteristics at different stages of production, which will cause the management measures implemented by gas wells in different stages to have different effects on efficiency[1-2]. Based on the complex production law of water-producing gas wells in SM Gas Field, this paper is based on the quantitative evaluation of the impact of water production on gas well development indicators for the latter. Clarify the reasons for the production of water and water from gas wells, understand the production rules of water-producing gas wells, optimize the management measures of water-producing gas wells in SM Gas Field, and clarify the rational production allocation methods and work under various complex water-producing conditions during the development of water-producing gas wells system[3]. It can also lay a foundation for the subsequent development of low-yield and low-efficiency wells to tap potential measures, to propose technical countermeasures to enhance oil recovery in the SM gas field, and to carry out gas field-related stable production potential evaluation.
