Ensuring effective sealing of casing columns in boreholes requires the use of the appropriate technology of cement slurry injection into the annular space and the use of a properly designed cement slurry recipe. Very often, when selecting the technological parameters of the cement slurry, special attention is paid to the technological parameters of the fresh cement slurry, but little attention is paid to the mechanical parameters of the cement sheath that is being formed (the cement slurry after setting). In order to improve the parameters of the hardened cement slurry in the annular space, the cement slurry of a new generation with increased durability (so-called geopolymers) is used. Slurries based on geopolymers are obtained by modifying slurries based on common-use cements with mineral additives with pozzolanic or hydraulic properties. Most often, these additives are fly ashes from the combustion of hard coal or ground granulated blast furnace slags. The article presents the results of testing the mechanical parameters of hardened cement slurries prepared on the basis of CEM V multi-component cement. It was found that the increase in the amount of silica fly ash in the slurry causes a delay in the strength growth rate; such slurries have lower values of early strength. The water–cement coefficient has the strongest influence on the mechanical parameters. The test results are also statistically developed, thanks to which it is possible to select the appropriate mathematical model, and this enables the prediction of mechanical parameters for slurries as a function of their hardening time. Such a mathematical solution can save some labor-intensive research, which, however, cannot be omitted in the final stage of slurry design.

“…В последние годы было проведено значительное количество исследований, направленных на разработку геополимерных составов для цементирования нефтяных и газо-вых скважин [18][19][20][21]. Их результаты показали, что данные системы обладают сопоставимыми с портландцементом прочностными характеристиками, низкой проницаемостью, устойчивостью к воздействию бурового раствора и пластовых условий, способностью к самовосстановлению [22][23][24][25][26][27][28].…”

Geopolymer systems are quite successfully used in such operations as industrial and civil construction, production of fire - resistant concrete, isolation and disposal of radioactive waste, etc. The oil and gas industry was no exception. They are one of the most promising alternatives to Portland cement in insulation operations. They allow achieving sufficiently high performances of well construction strength, corrosion resistance, and in some compositions these parameters significantly exceed those of Portland cement. In recent years, a significant amount of research has been carried out aimed at the development of geo polymer compositions for cementing oil and gas wells, which showed that these systems have strength characteristics comparable to Portland cement, low permeability, resistance to drilling mud and reservoir conditions, and the ability to self-repair. However, despite all the advantages of Geo polymer systems, their most significant disadvantage is poor regulation of rheological properties. Geo polymers (GP) with low ash content do not provide the proper rheological characteristics for the use in insulation operations. Low values of pumpability of solutions are still a serious restriction for wide practical implementation. The use of geopolymer solutions with the correct selection of the compositional composition capable of demonstrating significant improvements in strength and rheological parameters as a result of mixing with anhydrous drilling fluids is a very promising solution to this problem. The paper presents the results of research on the additives of non-aqueous fluids such as oil- based and synthetic-based drilling fluids and inverted emulsion drilling fluids on rheology of geo polymers. The obtained results allow stating that the rheological parameters of geo polymer compositions improve up to comparable values with Portland cement, which considerably extends the range of application of these solutions to use in operations of primary, squeeze cementing and well workover.

“…Any new material must enable the cement to be stronger, more durable, flexible, resilient to shocks, and easy to pump. Several types of nanomaterials such as nanosilica, nanoclay, nanoiron oxides, and nanotitanium oxide have been investigated in oil well cementing applications. − Suppiah et al and Ahdaya et al investigated geopolymers using fly ash as an alternative to Portland cement.…”

The cement sheath between casing and formation is required to have long-term sustainability for the longer life of the well. Different formulations based on different additives are prepared and pumped down into the annulus between casing and formation. In the past, sodium silicate and some other silicates had a wide range of applications in conformance control and water shutoff. Mostly silicate-based systems were used as extenders and accelerators in oil well cementing. In this study, a novel silicate system, aqueous alkali alumino silicate (AAAS) was tested in oil well cementing. There have been limited applications of an AAAS-based cement system reported in the literature. Nondestructive compressive strength and rheological properties such as plastic viscosity, yield point, and gel strengths of silicate-based cement slurries were measured. The AAAS was added in (3, 5, and 8) wt % (% by weight of water) into the cement slurry and cured at 50 °C and 2000 psi for 24 h in an ultrasonic cement analyzer. The evolution of compressive strength was measured with time. The rheological properties were measured at 50 °C and atmospheric pressure using an atmospheric viscometer. The performance of AAAS was compared with 5 wt % sodium silicate and simple Class G cement. The scratch strength of 5 wt % AAAS and sodium-silicate-based cement slurries were tested and compared. It was observed that the addition of a novel silicate system increased the compressive strength. In addition to that, the novel silicate provided an accelerating effect in the development of compressive strength. The rheological properties increased with an increase in concentration. The yield point was mainly affected by the addition of AAAS. The application of a novel silicate could be a strong alternative for sodium silicate in area of oil well cementing because of its promising results of compressive strength and rheology. It has a high tolerance toward contamination as compared to sodium silicate reported in the literature. The nondestructive compressive was increased by 33% upon the ddition of 5 wt % AAAS. Furthermore, AAAS increased the yield point from 15.94 to 24.64 lbf/100 ft2 at 5 wt % concentration. The AAAS solution is preferable in shallow gas wells of depths less than 3000 feet and 60 °C temperature. In those wells, AAAS can be pumped along with cement slurry for its quick setting. The AAAS can also be applied as an extender during cementing of low breakdown pressure formation or depleted zones.
