| Summary: | ABSTRACT Formation clogging in carbonate gas reservoirs is a significant challenge in natural gas extraction, particularly due to the complex mineral composition and physicochemical characteristics of carbonate rocks, which make clogging phenomena even more complex. This study aims to delve into the formation mechanisms of formation plugs in carbonate gas reservoirs by analyzing the chemical composition, mineral characteristics, and organic components of the clogging materials. Formation clogging usually results from multiple factors acting together, including the migration of rock particles, scaling of formation water, deposition of organic matter, and corrosion of downhole equipment. These clogging materials not only hinder gas flow but may also accelerate the corrosion of pipelines and other facilities, increasing maintenance costs, and in severe cases, leading to gas well failure. Although numerous studies have focused on formation clogging in carbonate gas reservoirs, a comprehensive understanding of their complex mechanisms of action is still lacking. This paper employs advanced analytical techniques such as X‐ray diffraction (XRD), gas chromatography‐mass spectrometry (GC‐MS), and X‐ray photoelectron spectroscopy (XPS) to analyze clogging materials from the Pengtan‐1, which is part of the Ancient Carbonate Reservoirs, in the Sichuan Basin. The results indicate that the clogging materials are complex, consisting of a mixture of inorganic and organic substances, and multiple factors synergistically contribute to the formation of clogging. The study provides new insights into the formation mechanisms of clogging materials and offers a theoretical basis for developing more effective prevention and control strategies. This research provides significant support for improving the development efficiency, stability, and economic viability of carbonate gas reservoirs. |
