Документ Моделювання полегшеного тампонажного каменю з домішкою цеолітового борошна(Національний технічний університет "Харківський політехнічний інститут", 2023) Орловський, Віталій Миколайович; Кузьмичев, Богдан В.The purpose of this work is to obtain a statistical mathematical model of a modified lightweight tamponage stone with a lightweight admixture – finely dispersed zeolite powder (flour) with a response function - stone strength. In particular, the task is to establish the effect of the modifying admixture - zeolite flour on the strength of the tamponade stone. Method. A rotatable central composition experiment plan was used to create a statistical model. The obtained results were processed using the method of computer mathematical modeling using the program STATGRAPHICS Plus for Windows. The results. A modified lightweight tamponage material with a lightweight admixture - finely dispersed zeolite flour was created and studied. A statistical mathematical model of stone strength based on lightweight tamponage material was obtained, depending on the content of components in the mixture and hardening conditions. The resulting mathematical model can be used for engineering evaluations of the influence of factors on the strength of cement stone and is fully confirmed by the physical and chemical processes that occur during hardening of the tamponage solution. Scientific novelty. The scientific value of this work lies in the fact that the selection of optimal recipes of the new modified lightweight tamponage material, intended for use in difficult mining and geological conditions of oil and gas wells, was carried out. Practical significance. The results of the work have practical application in the cementing of deep wells in oil and gas fields and geological exploration areas in difficult mining and geological conditions of oil and gas fields of Ukraine.
