Цементи тампонажні спеціальні використовуються для зміцнення нафтових і газових свердловин – цементування обсадних труб (колон).

Special cement grouts are used to strengthen oil and gas wells – cementing casing pipes (columns).
The main brands of special cement:
– Cements weighted slag grouting type: UShTs 1-120, UShTs 1-200, UShTs 2-200 (TU U 320.00136751.010-96):
Weighted slag grouting 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 the isolation of saline deposits.

– Weighted cement grouting 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 pressure, installation of cement bridges for various technological purposes, including for the isolation of saline deposits.

– Lightweight cement grouting type 1,5-100 (TUU 320.00136751.021-97):
Designed for cementing oil and gas wells in the temperature range from 50 to 100 ° C, overburden zones with abnormally low hydraulic fracture pressure gradients. The use of CTOs allows high-quality cementing of wells with difficult geological

– Slag sand cements of types CHPS-120 and CHPS-200 (TUU 320.00136751.008-96):
Designed for cementing oil and gas wells, isolation of salt deposits at bottomhole temperatures from 80 to 250 ° C and reservoir pressure up to 600 bar. Significantly differ from Portland cement in high heat resistance in relation to calcium chloride, sodium chloride, magnesium chloride and sulfate aggressive environments.

– Cement grouting for cyclically varying temperature type TsTPN (TU U 320.00136751.023-97):
Designed for fastening wells that are operated using thermal methods of stimulating the formation during cyclic heating of the lining to 150 ° C. Also used at moderate and elevated bottomhole temperatures.
