Annotation:

The authors of the article state the fact that by now neither substantiated physical criterion nor exact methods of fastening quality assessment have been found, since it is very difficult to reproduce well conditions when conducting experimental work in order to establish a large number of simultaneously acting factors on the durability of wells lining. In this regard, there is no generally accepted method in the world that is applied for testing cementing materials and the problem of the required strength of the stone for various cementing materials intended for cementing casing strings and installing cement bridges has not been solved. Leading global drilling service companies (Schlumberger, Halliburton, etc.) do not use special cements such as UCG, OCG, etc., but prepare their own mixture specifically for each cementing process, based on one basic cement selected for these oil and gas fields. Using various types of weighting agents, lightweight and other additives for mixing with the basic cement, a cementing system required for a specific well is obtained. All over the world, these systems are prepared at specially equipped bases. The studies conducted give reason to assert that, provided that modern technology and equipment are available, high-quality lightweight, normal and weighted cement mortars can be obtained based on local raw materials.
