The correct way to pay for a well leak in an oil well is to add plugging material to the drilling fluid.There are fiber products (such as paper, cottonseed shells, etc.), particulate matter (such as nut shells), and flakes (such as flake mica).The above materials in proportion to the combination together, that is Nut Plug.
It is suitable for plugging drilling fractures and porous formations, and is better if mixed with other plugging materials.
Characteristics
1.For pores and micro cracks leakage, plugging speed is fast, good effect.
2.It can quickly form an impermeable shielding band with certain strength to prevent the liquid and solid phases in the working fluid from intruding into the reservoir, so as to prevent the reservoir from damage. The shielding band can be removed through perforation and backflow.
3.It can significantly reduce the filtration loss of mud without affecting the rheological property of mud and has excellent temperature resistance.
4.Not affected by electrolyte pollution, non-toxic, harmless.
Method of Use
1. Amount of leakage prevention: 1-2%.
2. Seal the pores and micro-cracks of the sand layer and protect the reservoir, the dosage is 2-4%.
3. Seal the seriously lost layer, dosage 4-6%.
Application
It is suitable for plugging drilling fractures and porous formations, and is better if mixed with other plugging materials.
Storage and package
Stored in cool,dry and ventilated place.
