OPPORTUNITIES FOR USING INNOVATIVE SHAPE MEMORY EFFECT MATERIALS IN OIL INDUSTRY

Abstract

The discovery of the shape memory effect (SME) in the field of metal physics was the beginning of a large stage of research on new materials with specific properties Titanium nickelide (NiTi) is known as an alloy that exhibits a large-size shape memory effect and at the same time has good strength, ductility and corrosion resistance. The practical application of these materials in various devices began only in the seventies of the last century. This paper is devoted to the study of the possibility of using SME materials for solving particular problems in the oil and gas industry, including the use of the SME materials as connecting elements for pipelines and reinforcing bars for foundations of large-sized structures used in difficult engineering and geological conditions. These proposals will ensure a significant margin of safety for the oil and gas facilities under consideration and their safe operation. The analysis of domestic and foreign works on the use of SME materials in various areas of the oil and gas industry is fulfilled. Information on the basic physical, mechanical, and functional properties of SME alloys is given. The theoretical substantiation of the effective use of SME materials as sleeve couplings for field pipelines as an alternative to flammable welding at fire hazard enterprises, as well as the use of prestressed reinforcement SME alloys for the construction of plate foundations for large hydrocarbon reservoirs instead of traditional reinforcement, has been carried out. Calculation of stresses and strains in the ANSYS software environment has shown the high potential effectiveness of applying the SME technology to implement the described tasks.
