Sealing agent 801 drilling
Department of sealing agent 801 with the drilling of natural plant polymer composites modified with good sealing function bridging water swelling, adhesion strong, with traditional sealing agent, compared with the drilling, not size, "match"restrictions apply to all kinds of mud systems.Can be used to block the thief zone, but also to protect the low-pressure zones (oil, gas, water, etc.).
Physical and chemical properties:
Appearance: white powder.Size: 40 mesh standard sieve ≤ 10%.
≤ 10%. Moisture: ≤ 10%.PH :8-9.
Mud Performance:
Project-based pulp-based pulp 801 +4% Density, g/cm3 1.03 1.03 Apparent viscosity, mPa.s 7-10 ≤ 11 Plastic viscosity, mPa.s 6-9 ≤ 10 API fluid loss, ml 15-17 ≤ 10 Closed filtration, ml/30min total loss ≤ 50
Features:
Loss of porosity and micro cracking, plugging fast and effective.
Quickly formed a certain intensity with non-permeable shield to prevent the working fluid in liquid and solid invasive reservoir, the reservoir from damage, shield with anti-handling can be lifted through the perforation.
Can significantly reduce the amount of fluid loss mud, without affecting the rheological properties of mud, heat and excellent performance.
Pollution from the electrolyte, non-toxic and harmless.
Application:
The amount of 1-2% to prevent leakage.
Plugging the pores and micro cracks sand to protect the reservoir, the amount of 2-4%.
Serious leakage sealing layer, the amount of 4-6%
Packaging:
Three in one paper and plastic packaging, 25Kg / bag. |
