Southwest Oil and Gas Focuses on Corrosion Inhibition Technology to Ensure the Stable Production of Gas Wells

Sinopec News Network News As of the end of September, the Process Research Institute of the First Gas Production Plant of Southwest Oil and Gas Branch has completed a total of 192 well-times of iron ion concentration detection in 6 deep wells of Xujiahe Formation including Dayi 101 and Xin 601, focusing on corrosion inhibition.

"Iron ion concentration is an important indicator of downhole pipe string corrosion monitoring and plays a pivotal role in the process of gas well corrosion protection.

The time shifted to April this year.

After many on-site sampling, tests, and demonstrations, it was finalized in September to add corrosion inhibitor pre-filming to Well Xin601 to protect the production string of the gas well

"Of course, the corrosion inhibitor filling process parameters are not static

For this reason, the technicians stick to the laboratory, from sampling to agent sampling test, performance evaluation, and finally determine the optimized filling cycle.

Strengthening the management of chemical agents, being responsible for every data, strictly controlling the process design, and continuously improving the quality of process implementation are the quality management concepts that the Process Research Institute team has always followed.
