801 drilling plugging agent

801 drilling plugging agent modified natural polymer composite material, has good water swelling bridging plugging function, strong adhesion, and compared with the traditional drilling plugging agent, the particle size of "matching" restrictions apply to all kinds of slurry system. Can be used to seal the leak layer, also can protect the low pressure reservoir (oil, gas, water etc.).

Physicochemical properties:

Appearance: white powder.

Size: 40 standard sieve sieve residue is less than or equal to 10%.

 

The moisture is less than 10%.

PH:8-9.

Mud performance:

project Base mud Slurry +4%801

The density of g/cm3. One point zero three One point zero three

The apparent viscosity of mPa.s. 7-10 Less than or equal to 11

The plastic viscosity, mPa.s 6-9 Less than or equal to 10

API water, ML 15-17 Less than or equal to 10

Closed filter loss, ml/30min Total loss Less than or equal to 50

Characteristic：

The pore and micro crack leakage, sealing speed, good effect.

It can form a non permeable shield with certain strength with a block of solid and liquid working fluid penetration in reservoir, the reservoir from damage by perforation anti shielding belt can be lifted.

Can significantly reduce mud filtration, and does not affect the rheological properties of slurry, excellent heat resistance.

Without electrolyte pollution, non-toxic, harmless.

Application:

The amount of leakage prevention 1-2%.

Sand plugging pores and micro cracks, reservoir protection, the amount of 2-4%.

A serious plugging leakage layer, the amount of 4-6%

Packing：

Three in one paper plastic packaging, 25Kg/ bag.
