Abstract
Prilagođavanje komercijalnih vrsta domaćih ce-menata za upotrebu pri cementiranju dubokih bušotina je proces kojim jugoslavenska naftna privreda nastoji samostalno rješavali probleme kvalitetnog opremanja tih bušotina, U težnji pronalaženja domaćeg, jeftinog i djelotvornog usporivača vremena zgušćavanja cementne kaše, obavljena su ispitivanja primjenjivosti vinske kiseline. Osim provjere potrebnog sadržaja vinske kiseline za poželjna reo-loška svojstva, provjereno je i djelovanje tog dodatka na svojstva dobivenih uzoraka cementnog kamena.Adaptation of commercial types of domestic cements for use in cementing the deep wells is a process by which Yugoslav oil industry tends to solve problems of completion of those wells independently. In order to design a domestic, cheep and effective retarder, tests of applicability of wine acid on cement slurries have been carried out. Besides examining the necessary wine acid content to achieve desirable Theological properties, the influence of this additive on properties of hardened cement samples has been tested too
