“…In other words, it is assumed that associates of polymer molecules are formed in a water-polymer jet (without experimental proof). 18 In 10,13 , the high destructive capacity of a high-velocity jet of a polymer solution is associated with the deformation effects that occur during the flow of aqueous solutions of polymers under tension.…”

“…4 This is primarily due to the interest in work on the dynamics of polymer chains in convergent flows, because a strong deformation effect on macromolecular coils must take place in the inlet of the nozzle of the hydroperforator. 10,11 The most significant results in the study of the structural changes in polymer solutions under the action of a homogeneous longitudinal hydrodynamic field were obtained by Brestkin. 8 The main result of this work is the proof that in the conditions of a homogeneous longitudinal hydrodynamic field, dynamic phase transitions are possible.…”

The aim of the study is to develop an efficient, innovative method of perforating oil and gas well casing strings with a high-velocity stream of polymer solution that conserves resources and energy and meets the requirements for environ- mentally friendly hydrocarbon production. New knowledge about the dynamics of polymer solutions in the model conditions of flow through the nozzles of the hydro perforator, which form a high-velocity jet, became the main scientific basis for substantiating the water-polymer method of hydro perforation of oil and gas wells. The study of the reaction of polymer solutions to tension hydrodynamic influence allowed to formulate a structural concept, the "common denominator" of which is the strong deformation effect of tension hydrodynamic field on high molecular weight coils, which, according to nonequilibrium thermodynamics, should cause a kind of high elasticity. Peculiarities of hydrodynamic behavior of aqueous polymer solutions in model conditions of flow through jet-forming nozzles are studied. The possibility of transition to a highly developed state of the tangle of polyethylene oxide macromolecules in the conditions of the inlet section of the nozzle of the hydro perforator has been experimentally proved. The mechanism of perforation of oil and gas wells by a high-velocity jet of an aqueous polymer solution has been elucidated. It is proved that the mechanism of the high cutting ability of the high-velocity jet of aqueous polymer solution is the destructive effect of the dynamic pressure of water-polymer jet "reinforced" by highly developed macromolecular chains in the inlet nozzles of the hydro perforator nozzles under the action of tensile leakage. Experimental and industrial testing of the method of perforation of wells by a high-speed jet of an aqueous solution of polyethylene oxide confirmed the practical and economic feasibility of its use.

The multi-authored monograph Prospects for developing resource-saving technologies in mineral mining and processing is brought to your attention. Problems of environmental management have always been important for humanity. Yet, they have acquired the greatest relevance in recent years as human economic activity have greatly affected the natural environment. There is a need to develop scientific principles of environmental management based on the principles of sustainable use of natural resources via resource-saving technologies and optimal placement of production facilities. The monograph considers application of resource-saving technologies to mining mineral deposits. The authors apply a comprehensive approach to solving this problem by analyzing the entire range of works related to mining and processing of minerals. The monograph examines resource-saving technologies in open pit and underground mining of ore and non-metallic minerals. The monograph is intended for a wide audience of mining scientists, practitioners, postgraduates and students.

“…It was previously proved that convergent flow is a superposition of currents undertension and shear forces [23]. This is primarily due to the interest in work on the dynamics of polymer chains in convergent flows, because a strong deformation effect on macromolecular balls must take place in the inlet of the nozzle of the hydroperforator [24].…”

There has been carried out a complex study of polymer solution reaction under hydrodynamic effect. Integrated approach turned out to be a necessary condition for successful solving of the set tasks of scientific and technical character (from fundamental studies to concrete technological process). This allowed to formulate a new structural concept with a “common denominator” such as strong deformation effect on the part of a hydrodynamic field on macromolecules that immediately generates the so called rubber-like high elasticity. The technologies of production oil and gas is based on utilization of rubberlike properties of a polymer solution that arise under definite conditions while going through porous media, nozzles and slotes. There have been obtained eco-technological criteria and practical recommendations as to practical implementation of technologies of production oil and gas.
