Dissolving Frac ball
|Main material: Aluminium magnesium alloy nano materials|
|Working in the water under 150℃.|
|Compression strength: 70MPa under the range of 1/4, 1/8.|
|Dissolution medium: 3-5% KCl or NaCl solution.|
|Melting temperature: According to the temperature of oil-field, higher temperature, the speed of dissolving more faster.|
|Cracks, scratchs, chips could not be allowed on the ball’s surface.|
|Tolerances of diameter:±0.02-0.03mm|
|Application||For fracturing horizontal well of a large bridge plug piecewise.|
|For fracturing well of open hole packer sliding sleeve.|
|For fracturing well of multistage packer.|
|For wells of low pressure and easy to cause negative pressure.|
Test conditions of Dissolving balls
|1. Dissolution medium(Test liquid): 3-5% KCl or NaCl solution.|
|2. Temperature of test liquid: 70-90℃|
|3. The total volume of test liquid: 2-3L|
|4. Time: Replace the dissolution medium(test liquid) every 5 hours later.|
|5. Before replacement of test liquid, record the changes of the ball’s diameter and weight.|
|6. After testing continuously about 7 to 15 days, can observe the best effect.|
(1)Can be used in the opening of layered fracturing sliding sleeve.
(2)Due to the low density of the ball (1.85 1.9 g/cm3), flowback faster, can return ahead of completely dissolved.
(3)The speed of dissolution related with the working temperature and the structure characteristics.
(4)Can be dissolved in the KCl or NaCl , it is recommended to use 3% KCl or NaCl .
