Power adhesive

Product Details

Product name: Power adhesive

Production process:

In 35% xanthan gum liquid, add 25% water-absorbing resin and 15% guar gum powder, stir strongly for 30 minutes, then dry at 85°C for 3 hours, and finally make granules.

The classification of plugging methods: Chemical plugging

The principle of leakage plugging:

1: Expansion, can expand to more than 10 times its own volume, blocking the leakage channel.
2: Bonding, Power adhesive particles bonded together with each other, in the leakage layer to form the strength of the great strength of the mesh colloid, adhering to the leakage of the layer of rock, greatly increasing the leakage of the layer of its own pressure-resistant ability, so that the mud can not enter the leakage layer.

Plugging features:

1)effect: no matter porous leakage, or fissure small leakage, medium leakage, large leakage to loss of return leakage, can be plugged.
2) dosage: 0.25 tons to 0.5 tons.
3)time: no need to start drilling, plugging at any time, from the addition of material to the end of the fight replacement slurry only 2 hours, plugging time than the conventional pressure plugging to reduce the number of more than 1 day and a half.
4)no aftereffects, do not block the screw does not affect the directional signaling.
5)no need to use a feeding funnel, just put two sewage pumps in the distribution tank, and then you are a person. No need to use charging funnel, only need to put two sewage pumps in the slurry tank, charging only one person.

Methods of use:
1)Additive quantity: 1% to 2%, i.e. 10 kg to 20 kg per 1 cubic meter of water.

2) Mixing time: 10 to 20 minutes from the beginning to the end of dosing, and then pump it into the well immediately and press it into the leakage layer.

3)Static time: After all the leakage is pressed into the leakage layer, start drilling for 300 meters and leave it for 2 hours, then drill down.

4)Plugging volume: 1) 30 m3 for small and medium-sized leaks; 2) 60 m3 for large leaks; 3) 90 m3 for lost-return leaks.

5)Insufficient pressure: Inject the plugging mud into the bit location and then close the packer. After all the plugging mud is injected into the well, flush the water tank with clean water, use clean water as replacement slurry, pour the replacement slurry into the drill pipe, and then start stationary drilling.

6)It takes 3 hours for the strong bonding agent to swell and gel strength to develop. After replacing the mud, never continue to turn on the pump to circulate, otherwise the strong binder in the mud will be pressed far and diluted, and eventually fail.

7)Two hours before the strong binder enters the seepage layer, the gel has not yet formed sufficient strength, so the replacement mud is pumped without pressurization.

8)No vibrating screen is used: Since the strength of the strong binder is still strong in the well or the residual part of the mud tank, it will remain on the vibrating screen, therefore, the vibrating screen can be used without vibrating screen 8 hours before the start.

9)Pressure-bearing capacity: 1 can ensure that the specific gravity of the slurry to mention 1.22 does not

leak; 2 with the formation pressure enhancer, can ensure that the specific gravity of the slurry to mention 1.26 does not leak; 3 with controllable gel, can ensure that the specific gravity of the slurry to mention 1.45 does not leak.
