Special Cements UShTS -2-200 Big-Bag 1000 kg. Special Cements UShTS -2-200 Big-Bag 1000 kg.

Special grouting cements are used to strengthen oil and gas wells - cementing casing pipes (strings).
The main brands of special cements:
- Weighted slag backfill cements of the type: UShTs 1-120, UShTs 1-200, UShTs 2-200 (TU U 320.00136751.010-96):
Weighted slag backfill cements of the UShTs type are intended for cementing oil and gas wells with reservoir temperatures from 80 to 250 ° C, with abnormally high (up to 600 Atm) pressures, including for isolation of saline deposits.

- Weighted backfill cements of the type: TsTU 1-100 and TsTU 2-100 (TU U 320.00136751.022-97):
They are used for cementing oil and gas wells with moderate temperatures (up to 100 ° C) and in the presence of zones of abnormally high reservoir pressures, installation of cement bridges for various technological purposes, including for isolation of salt deposits.

 
- Lightweight backfill cement type TSTO 1.5-100 (TU U 320.00136751.021-97):
Designed for cementing oil and gas wells within the temperature range from 50 to 100 ° C, overburden zones with abnormally low hydraulic fracturing pressure gradients. The use of CTO allows high-quality cementing of wells with difficult geological conditions and, if necessary, ensures the rise of the cement slurry to a great height by one degree.
- Slag-sand cements of the ShPTsS-120 and ShPTsS-200 types (TU U 320.00136751.008-96):
Designed for cementing oil and gas wells, isolating salt deposits at bottomhole temperatures from 80 to 250 ° C and reservoir pressure up to 600 atm. Significantly differ from Portland cements in high heat resistance in relation to calcium chloride, sodium chloride, magnesium chloride and sulfate aggressive media.
- Backfill cement for cyclically changing temperatures of the TsTPN type (TU U 320.00136751.023-97):
Designed for casing wells operating using thermal methods of stimulating the formation with cyclic heating of the support up to 150 ° C. Also used at moderate to elevated bottomhole temperatures.
