Annotation:
Due to the development of thermal methods when developing high-viscous oil fields, high requirements are imposed on the wells cementing tightness, the construction of which is accompanied by abnormally low reservoir pressure (ALRP) and intensive absorption. Thetemperatures in the well cementing zone in the productive formations interval range from +8 to +320 °C. The foam-cement technology based on the "Carbon-Bio" cement mixture requires further improvement due to the low adhesion quality of the cement stone. The technology proposed in the article makes it possible to achieve improvement of the well cementing quality and an increase in the acoustic resistance of cement stone without deteriorating its physical and mechanical characteristics.
