🛢️ offshore oil production platform: Anti-corrosion of pipelines and equipment in high-salt and high-chlorine environments

FAQ

How to choose between OEM and BXH-105?

OEM custom suits customers who need formula customization, private-label tolling, or sample matching; BXH-105 (enhanced grade) is a standard stock product better suited to high-flow oil-phase pipelines in refining units.

How to determine the filling amount?

The general reference dosage is 50~200 ppm (based on water injection volume), and it can be appropriately increased to 300 ppm in high corrosion areas. It is recommended to conduct a small test on site first, measure the actual corrosion inhibition efficiency through the coupon method, and then determine the optimal filling amount. We can provide technical support.

In-depth analysis: OEM Custom Imidazoline (OEM formula)

The corrosion environment of the oilfield gathering and transportation system is complex, with the combined effects of CO₂, H₂S, SRB sulfate-reducing bacteria, and high-salinity produced water, and the produced liquid has a high moisture content. Ordinary oil-soluble corrosion inhibitors often have a tendency to assist emulsification, which will increase the difficulty of dehydrating crude oil and affect the operation of electric dehydration. OEM Oilfield anti-emulsifying imidazoline Low emulsification tendency It is a core design that effectively inhibits corrosion while not interfering with subsequent dehydration treatment. as High temperature and high pressure oilfield corrosion inhibitor and Acidic environment imidazoline, OEM is suitable for acidic gathering and transportation conditions with high water content, high salinity, and CO₂/H₂S.

Corrosion characteristics of oilfield gathering and transportation

CO₂ generates carbonic acid and causes general/pitting corrosion, H₂S causes sulfide stress corrosion, SRB aggravates corrosion under scale, and high water content further amplifies the risk. It is necessary to consider both corrosion inhibition and demulsification compatibility.

Why demulsification is important

If the corrosion inhibitor assists emulsification, it will form a stable emulsion during the gathering, transportation and electric dehydration process, which will increase dehydration energy consumption and chemical costs. OEM has low emulsification tendency, is compatible with wax removal and anti-waxing agents, and does not affect dehydration.

Applicable scenarios and additions

Suitable for high water content oil well gathering pipeline network and water injection system with water content >60%, operating temperature 20-120℃, recommended 20-50 mg/L.

Typical application scenarios

High water cut oil well gathering and transportation

Moisture content >60%

Low emulsification tendency, corrosion inhibition while not affecting crude oil dehydration and electric dehydration operations.

Water injection wells and water injection systems

CO₂/H₂S Environment

Inhibit acid gas corrosion of water injection pipelines and downhole pipe strings.

CO₂ flooding/sulfur oil field

Gathering and transportation trunk lines

For CO₂, H₂S composite corrosion film protection, compatible with fungicides.

Technical Q&A

What are the main types of corrosion faced by oilfield gathering and transportation pipelines?

It is mainly comprehensive and pitting corrosion caused by the dissolution of CO₂ to generate carbonic acid, sulfide corrosion and stress corrosion caused by H₂S, and subscale corrosion caused by SRB bacteria. Superimposed on high water content and high salinity produced water, the corrosion risk is significant.

Why must oilfield corrosion inhibitors resist emulsification?

If the corrosion inhibitor assists emulsification, a stable emulsion will be formed in the gathering, transportation and electric dehydration links, which will increase the difficulty of dehydration, energy consumption and the amount of demulsifier. OEM has low emulsification tendency and does not interfere with dehydration while inhibiting corrosion.

How to choose corrosion inhibitor for water injection well containing CO₂/H₂S?

Give priority to products that have good film-forming properties against acidic gas corrosion, resist emulsification, and are compatible with fungicides. OEM is optimized for the working conditions of high water-containing acidic media in oil fields, and is suitable for water injection wells and gathering and transportation trunk lines.

Can OEM be injected together with wax remover and fungicide?

Can. OEM has good compatibility with commonly used wax removers and fungicides. However, water quality varies greatly in different oil fields. It is recommended to conduct a small sample compatibility test first. We can provide compatibility evaluation support.
