Dissolvable Frac Ball HCL Acid Resistance Test


Experimental purpose: Obtain the acid corrosion resistance of the coating soluble ball(dissolvable frac ball) in a certain temperature and certain concentration of HCL solution through experimental observation


Experimental steps:

1. Prepare experimental equipment, soluble ball(dissolvable frac ball), solute (HCL), clean water, beaker, balance, vernier caliper Constant temperature water bath
2. Check the appearance and size of the soluble ball, and take a photo
3. Prepare 20% HCL solution
4. Immerse the coating soluble ball in HCL solution
5. The constant temperature box maintains the HCL solution at a certain temperature, and observes the acid corrosion resistance of the soluble ball
6. Take out the soluble ball at intervals, check the appearance, shape and size of the soluble ball, and record the soluble ball weight, reconstitute the acid solution, continue to observe the corrosion resistance of the soluble ball


Test index: record the corrosion resistance of the soluble ball every 24 hours
Experimental considerations: every time during an acid resistance check, pay attention to safety, record relevant data and take pictures clearly

Solution preparation and appearance of acid-resistant soluble ball

Remarks (appearance of dissolvable frac ball): smooth and bright surface

 

Corrosion resistance after 24h

 

Corrosion resistance after 48h

 

Corrosion resistance after 60h

Remarks (appearance of soluble ball): The soluble ball is corroded with a few holes, the largest hole diameter is 6mm, and the depth is 2mm

 

Corrosion resistance after 72h

Remarks (appearance of soluble ball): The gap of the soluble ball is slightly deepened, the gap diameter is 30mm, and the depth is 11mm

 

Experimental results:

The coating soluble ball is at 70℃, 20% concentration of HCL solution, within 24 hours, the acid corrosion resistance is good, and the soluble ball coating is intact; 24-48 hours, the soluble ball has a few holes, 48-60 hours, A slightly larger gap appears, and within 60-72 hours, the gap is slightly deepened and enlarged.
