The invention relates to exploration of oil and gas wells. According to the invention, a special cable for geophysics containing one or several electrically isolated leads comprises a multilayer sheathing made from steel wire. Such a cable has a higher hardness and rupture strength but still has a required flexibility. It makes it possible to perform works in vertical or horizontal wells and to use pushing devices and sealing systems for wellheads.
L'invention relève du domaine d'exploration de puits de pétrole et de gaz. Selon cette invention, un câble de géophysique spécial comportant un ou plusieurs fils conducteurs à isolation électrique comprend un revêtement multicouches en fil d'acier. Ce câble possède une résistance à la rupture et une rigidité élevées tout en gardant une souplesse nécessaire; il permet d'entreprendre des travaux dans des puits horizontaux ou verticaux, d'utiliser des dispositifs de poussage et des systèmes d'étanchéification des têtes de puits.
