摘要

In the paper the issue of development of cement composition on the basis of "Microdur" is considered. The method of mathematical planning of the experiment was used to justify the optimal formulation of the waterproofing composition, also the processing of the results of the study using the "full factorial experiment" technique, as well as the results of studies by the method of computer microtomography of the formed cement stone. Laboratory studies consisted in determining the possibility of obtaining a solid, clogging pore space of reservoir composition, both without additives, and with additives of a modifier and a plasticizer. The studies were conducted in three stages. The first stage included determining the time of formation and the quality of the insulating material. The second stage of the work was the study of kinematic viscosity and static shear stress of cement slurries. The third stage of the research was the study of the formed cement stone for compression after 2, 7, 28 days of hardening. The authors developed a technology for eliminating the inflow of bottom water using the developed waterproofing formulation and two waterproofing compositions (WPC) that differ in initial viscosity, time of hardening, strengthening properties and selectivity. The first portion of WPC is needed to cut off and precipitate the bottomhole watercone. As a cementing composition, it is recommended to use a cementing slurry on a micro-cement basis. Pumping down into the formation of the second insulating composition to create a shield in the plane of oil-water contact begins after the water cone is precipitated, the first composition hardened. As a second cementing solution, it is recommended to use a selective composition for repair and insulation works in oil and gas wells, also developed by the authors and including 10 vol. % of hydrophobizing silicone fluid (GKZh-11H), as a catalyst - 85 vol. % of ethylsilicate ETC-40, as thickener - 5 vol. % of diatomite.
