Abstract
This study presents an innovative approach to prevent wellhead equipment corrosion in the cellar by employing a composite gel of polyacrylamide (PAM) with sand to enhance mechanical strength. Experiments were conducted to investigate the effect of varying PAM-to-sand ratios on the composite gel's mechanical and corrosion inhibition capabilities. The mechanical properties, including stress and strain, were examined using a rheometer. The corrosion inhibition capability was evaluated using corrosion test coupons. The results showed a notable improvement in mechanical strength and corrosion resistance with the inclusion of PAM and sand. Among the tested ratios, a composite gel consisting of 10% PAM offered the optimal balance of mechanical strength and corrosion inhibition. This finding suggests that filling the cellar with a 10% PAM composite gel can significantly enhance the lifespan of wellhead equipment by effectively protecting it from corrosive agents. Further research will focus on optimizing the composite gel for improved performance and assessing long-term durability under real field conditions.
