Технологические решения для строительства разведочной вертикальной скважины глубиной 2820 метров на газовом месторождении (Тюменская область)

Цель работы — проектирование и строительства разведочной скважины глубиной 2820 метров. В процессе работы был составлен проект на строительство разведочной скважины на глубиной 2820м (по вертикали). Разработаны мероприятия по организации строительству, охране труда и окружающей среды. В работе рассмотрен вопрос идентификации и учета наработки на бурильные трубы с помощью RFID-меток. Дипломная работа выполнена с учетом современных достижений в области техники и технологии строительства нефтяных скважин.The purpose of the work is the design and construction of an exploration well with a depth of 2820 meters. In the process, a project was drawn up for the construction of an exploration well at a depth of 2820m (vertically). Measures for the organization of construction, labor protection and the environment have been developed. The paper discusses the issue of identification and recording of achievements on Boo-realnye pipe with the help of RFID. The thesis is made taking into account modern achievements in the field of technology and technology of construction of oil wells

Spin Caloritronics

Effects of combined current injection and laser irradiation on Permalloy microwire switching

Combined field- and current-induced domain wall (DW) motion in Permalloy microwires is studied using fast magneto-optical Kerr-microscopy. On increasing the current density, we find a decrease of Kerr signal contrast, corresponding to a reduction in the magnetization, which is attributed to Joule heating of the sample. Resistance measurements on samples with varying substrates confirm that the Curie temperature is reached when the magneto-optical contrast vanishes and reveal the importance of the heat flow into the substrate. By tuning the laser power, DWs can be pinned in the laser spot, which can thus act as a flexible pinning site for DW devices
