Abstract The boring log in the Eastern Siberia regions is characterized by presence of frozen rocks, which causes a number specific drilling problems. In such conditions, magnesia materials high expanding capacity are widely used for cementing wells. These improve well quality increasing areas complete contact at rock-cement and cement-casing boundaries. For their effective use, it important to evaluate parameters comparison with traditionally Portland cement-based plugging materials. cement...
The paper deals with well cementing, which is a complex engineering task requiring special tools and technologies. authors give an example of complications that arise due to the poor quality cementing. aim work study mineral ultrafine additive-nanosilicates, increase strength cement stone reduce its porosity. Nanosilicate formed during cleaning ore-thermal furnaces in metallurgical plants. One such technologies application waste, since it can improve environment by sludge fields from waste...
