At present, with the increasing in demand for natural gas, all gas production companies are increasing their efforts in natural gas exploration and development. Corrosion is one of the problems during the wet gas transporting, and this can be solved by adding corrosion inhibitor(CI) in most case. However, there are no standards for the Cis performance used in gas gathering and transportation pipelines, which may lead to some gapsbetweentheR&Dscientistsandtheneedsofcorrosioninhibitorusers. Based on the demand of some gas production companies for the CIs, this paper puts forward the performance requirements and corresponding indexes of Cis for natural gas gathering and transportation system, and given some advice on the evaluation method.

The performance requirements, corresponding indexes and laboratory evaluation methods of corrosion inhibitors have a direct impact on the selection of corrosion inhibitors. The performance requirements of corrosion inhibitor for natural gas gathering and transportation pipelines can be summarized into two aspects: corrosion inhibition and usability performance. Corrosion inhibition includes inhibition performance in aqueous phase and in TOL. Usability include compatibility, stability, pouring point, emulsifying tendency, etc. Based on the some different types of gas fields requirements, the performance requirements and corresponding indexes of corrosion inhibitors for wet gas gathering and transportation pipeline are analyzed, and the corresponding performance indicators of corrosion inhibitors for different types of gas fields are proposed. Finally, the commonly applied laboratory evaluation methods in current active standards have been analyzed and summarized, and verified.

Corrosion of pipelines made of carbon steel and exposed to wet hydrocarbons containing CO2 and H2S is a common but serious problem encountered in petroleum industry and its occurrence causes enormousexpense due to production downtime, accidental injuries, and replacement costs. Control and prevent corrosion using chemical treatment (e.g. corrosion inhibitor injection) is one of the most cost-effective solutions and commonly practiced methods to prevent corrosion failures in pipelines in oil and gas industry. Generally speaking, the active corrosion inhibitor (CI) components in commercial CI packages are usually organic, nitrogen-based surfactants such as amines, imidazoline and its derivatives. Due to the amphiphilic nature of surfactants, a good fraction of the injected CI will inevitably go into the oil phase through partitioning and to the oil/water interface.
