Hrymaniuk V. The development of the reinforced plugging material for well cementing (on the model of the reservoirs of the northwestern shelf of the Black Sea)

The thesis is devoted to the development of the reinforced plugging material for well cementing at the reservoirs of the northwestern shelf of the Black Sea. To provide the reliability of the borehole lining, the optimization of the cementing mixture composition along with the abnormal strained features of the plugging stone has been performed. The geological-technical conditions of the construction and the quality state of well cementing have been analyzed at the reservoirs of the northwestern shelf of the Black Sea. The available reinforced plugging systems and the criteria of their selection according to the well drilling conditions have been characterized. The impact of the mineral and synthetic mixtures on the features of the plugging stone has been investigated. Based on method of experiments rational planning it was conducted first stage of reinforce mixture components chosen with using of developed evaluation criteria and government standards.
