G403 Toughening Agent for Oil Well Cement Oilfield Chemicals Toughening Agent Oil Well Cement
Relying on Crack resistance and toughness properties of the composite fibers and utilizing fiber’s load transportation, G403 Toughening agent for oil well cementing can make the internal defect of stress of the cement disperse, and enhance the ability of impact resistance of the cement. With the flexural loads affection, G403 is able to improve load capacity of the cement to form a visible crack ,and then prevent the stress of cement cracking;At the affection of load, G403 can prevent the crack from expanding. And under strong impact loading, G403 can form a shield at the stress field of crack-tip, thus to significantly increase the toughness of the cement, to protect the oil and gas layer, to prevent brittleness defects due to perforation. At the same time, the product has a certain character of micro-expansion. It can compensate for the cement slurry (stone) shrinkage, and produce micro volume expansion, beneficial to prevent oil, gas and water channeling.
Non-toxic, odorless
Common dosage is 1.5%~2.5%(BWOC).
No adverse effects on slurry thickening time, rheology, free water and so on, significantly improve compressive strength.
