Как видно, введение в тампонажную смесь в качестве добавки хлористого кальци  существенно сокращает сроки схватывани  и увеличивает механическую прочность образующегос  цементного раствора. Так, начало схватывани  сокращаетс  примерно в 3 раза, а прочность повышаетс  более чем в 2 раза. Это позвол ет повысить качество креплени  скважин и сократить период ОЗЦ. При этом основные параметры прокачки состава сохран ютс  на оптимальном уровне.As can be seen, the introduction into the cement mixture as an additive of calcium chloride significantly reduces the setting time and increases the mechanical strength of the resulting cement slurry. Thus, the beginning of the setting is reduced by about 3 times, and the strength increases by more than 2 times. This makes it possible to improve the quality of well casing and shorten the RFQ period. At the same time, the main parameters for pumping the composition are maintained at an optimal level.

Использование данной тампонажной смеси в услови х низких пластовых давлений значительно повышает надежность и качество креплени  нефт ных и газовых скважин , что дает значительный экономический эффект.The use of this cement mixture under conditions of low reservoir pressure significantly increases the reliability and quality of the attachment of oil and gas wells, which gives a significant economic effect.
