Acidizing Corrosion Inhibitor UZ CI-180

To protect assets such as tubulars and tools from highly acidic fluids used in acid fracturing operations that can cause severe corrosion.We provide a portfolio of acid corrosion inhibitors specifically designed to break down acids during hydraulic fracturing and acidizing treatments. Some of these corrosion inhibitors are more environmentally acceptable versus traditional corrosion inhibitors, thereby providing options for heavily regulated areas.

Protect downhole equipment and tubulars from corrosive environments, Corrosion inhibitors are based on our experience developing market-leading chemical compounds used throughout the energy industry.

UZ CI-180 is a high temperature resistant acidizing corrosion inhibitor for oilfield use. In the process of acidizing or pickling, the acid will corrode the steel, and at high temperature, the rate and range of corrosion will be greatly increased, therefore, in the oilfield production, the corrosion prevention of high-temperature pipe is particularly important, which is not only related to the benefits of oilfield exploitation, but also closely related to the production safety. The degree of acid erosion on pipelines and equipment depends on the contact time, acid concentration and temperature conditions, etc. UZ CI-180 has excellent high-temperature resistance, and at temperatures up to 350°F (180°C), the corrosion effect of acid on steel at high temperatures at the bottom of the well can be greatly reduced by adding UZ CI-180 to the acid mixture.

UZ CI-180 corrosion inhibitor can be used in matrix acidizing and production enhancement operations, production acidizing and production enhancement operations, and wellbore cleaning with acidic formulations.

The recommended dosage at different temperatures is as follows.

(Concentration depends on acid type, strength, wellbore temperature, contact time and additional additives)

1.Excellent high-temperature metal corrosion protection.

2.Provide corrosion protection in all HCL and HCL-HF blends up to 177℃.

3.Contains no heavy metal salts, and has a high flash point.

4.Reduces acid corrosion rates on common oilfield tubulars, including coiled tubing.

5.Improves design flexibility because it works in virtually all strengths of hydrochloric acid and mixtures.

6.hydrochloric-hydrofluoric and hydrochloric-organic acids.

7.Disperses easily in all acid-based fluids.

8.Can provide acid corrosion inhibitor protection for as long as 24 hours.

9.Can provide acid corrosion inhibitor protection for K55，J55, N80, CT80, QT800 and P110、P110S etc.

Test of specific gravity

1. Loading 250 ml sample into 250 ml measuring cylinder.

2. Place the measuring cylinder in a water bath and keep the temperature at 25℃.

3. Put in a densitometer to measure sample specific gravity, record it.

Test of pH value

1. Loading 100 ml sample into 250 ml beaker.

2. Place the beaker in a water bath and keep the temperature at 25℃.

3. Check the pH meter.

4. The pH value of the sample is measured by pH meter, record it.

Test methods of corrosion rate

1. Keep the oven temperature at 160℃.

2. Configure 200 ml of 20% HCL, adding predetermined amount of CI and INTENSIFIER.

3. Put prepared steel Coupons in the cell , seal, tighten, put in oven, preheat for 30 minutes at 160℃.

4. Start the timing and keep the Aging Cell for required exposure period in mechanical convection oven.

5. Take the cell out of the oven, cool, release the pressure, take out the metal coupon, clean, wash and weigh for any weight loss.

6. Calculate the corrosion rate in Lbs/Ft2 and g/(m2.h).

7. Check for any pitting on the metal surface and report.
