Description
G401 Expanding Additive for Oil Well Cement
Product Description
G401 expanding additive for oil well cement is of the cement hydration products, which can compensate for the grout (stone), shrink and produce volume micro-expansion. It is conducive to anti-channeling, compress cement porosity and improve the pores’ distribution, thus to achieve the goal of improving strength and reducing the permeability rate. And in restricted state, enhancing the product’s prestress and improving the bond strength of cement is good for preventing corrosion of the cement and casing pipes, and controlling loop current. G401 has a good compatibility with other additives, and does not affect the other properties of slurry. It has a wide scope of temperature allowance (25 ~ 150 ℃) and a good performance on salt tolerance.
Characteristics
Normal dosage: 2﹪~3﹪(BWOC)
It has no adverse effects on thickening time, rheological properties and the free water, and has significantly improved compressive strength.
It is suitable for cement slurry with normal and low density of cement slurry.
It is applicable for the wells with irregular enlarged diameter of well holes, and can adjust the balance pressure in deep wells, and anti-channeling and balance pressure during cementing wells. It can apply to high pressure cementing with active oil and gas.
It is preferred to be mixed without water.
