Annotation:

The article considers the design and actually used buffer and grouting materials to be used during the primary cementing of production wells in the mining and geological conditions of the Pestsovaya area of the Urengoy oil and gas condensate field. Design and actually used cement materials, at different pressures and temperatures in the annulus and inter-annular spaces, form shrinkage cement stones, taking into account the influence of chemical reagents, which leads to various complications of the primary cementing process in these geological conditions. A significant improvement in the quality of casing strings primary cementing in the conditions of the Pestsovaya area of the Urengoyskoye oil and gas condensate field can be achieved as a result of a reasonable choice of new highly effective component compositions of buffer and cement mixtures and improvement of technologies of their practical application.
