This product is a new type of degradable rigid plugging ball, which can also avoid the problem of fast pressure relief caused by too fast dissolution of common plugging agent. In order to improve the temporary plugging effect, the composite temporary plugging method of large particle temporary plugging agent+medium particle temporary plugging agent+fine particle temporary plugging agent is generally adopted, which is more flexible to adapt to the size of the complex fracture opening in the well and effectively plug.

       This product is made of natural green environmental protection biodegradable materials. At the formation temperature, solid particles are timely softened into mud and dissolved without residue. Its viscosity is close to that of water. It is easy to reverse flow and has little damage to the formation. It is an ideal plugging agent.

AND series temporary blocking ball

1. Use in aqueous solution or in aqueous vapor environment;

2. The working temperature is 60~120 ℃. The higher the temperature, the faster the dissolution. The total dissolution time is 8 h.

3. Compressive strength: 50~70MPa.

4. Good temporary plugging performance, convenient construction, fast dissolution rate and high construction success rate;

5. Particle size: 13mm, 14mm, 15mm, 16.5mm, 18mm (other specifications can be customized)

Degradation performance test

Test conditions for degradation performance: add 100ml of water, one plugging ball AND-1 * * in an airtight container, maintain a constant temperature of 75 ℃ for a certain time, and then filter the solution under water with a 40-mesh screen, collect the residual degradation on the screen, dry and weigh it, which is the undegraded quality.

Packaging, transportation and storage

Packaging carton drum, net weight of each drum 25kg, or customized according to customer requirements.

Storage: Store in a cool, dry and ventilated place to avoid moisture. Shelf life 24 months。
