It is intended for preparing dry cement mixtures required for cementing oil and gas wells with complex geological conditions, subjected to stress mechanical loads on the cement stone during drilling and well operation, including during multi-stage hydraulic fracturing, with the risk of lost circulation and leaks due to the formation of fracture channels.

Chemical description
BLOCK COPOLYMERS, MINERAL ADDITIVES. CA SHC - A COMPLEX ADDITIVE, A COMPOSITION OF UNIQUE DOMESTIC CHEMICAL REAGENTS, DEVELOPED FOR THE PREPARATION OF SELF-HEALING CEMENT.
Physical properties
Appearance: gray powder.
Solubility in water: partially soluble.
Solubility in water: partially soluble.
Advantages
- It self-restores under the influence of hydrocarbons without losing its strength properties and maintains tightness in the wellbore space;
- enhances adhesive properties and imparts elastic properties to the cement stone, low Young's modulus;
- eliminates microgaps (up to 1000 microns) between cement column/cement-rock;
- prevents interzonal crossflows of hydrocarbons (oil, oil, gas, gas condensate);
- endures multiple cyclic and temperature loads (including operation, pressurization, hydraulic fracturing, perforation during well completion without damaging the cement stone);
- minimizes expenses for repair and insulation works and profit loss due to production stoppage;
- extends the well's service life and its inter-repair period.
Recommendations for use
Can be used at temperatures from 20 to 200°C.
The recommended effective concentration of the complex additive is in the range of 10 to 40% by weight of dry cement (BWOC), depending on the required properties of the solution.
