Investigation and analysis of cement slurries

Abstract

Laboratory studies of grouting slurries and cement compositions corresponding to specific mining and geological conditions are an important link in the design and construction of wells. In this work, a study of the rheological and physical-mechanical properties of cement grouting mixture and grouting cements was carried out. In the research for laboratory tests, samples of ground-bed mortars "GranTSEM - 7 BG"and "CemFrost", "CemFrost Lite - 5"were used. For the qualitative process of cementing, the analysis of grouting slurries was carried out with the study of changes in the consistencies of grouting slurries over time. Thus, the acceleration of the process of drilling observation and production wells depends on the correct selected cement slurry. As a result, of the studies carried out, it was revealed that the introduction of additives into the cement slurry that bind the barrier water and the drilling fluid helps to reduce fluid loss and increases the specific surface area, which speeds up the drilling process.
