Abstract

Det er tilveiebrakt en brønnloggingsanordning som får brønndata innsamlet ved hjelp av en sensor nede i hullet overført til overflaten via komplementære modemer, og transportert til overflatemodemet via en dataoverføringskabel som forbinder modemene med hverandre, idet kabelen har minst et par med isolerte ledere viklet som et hovedsakelig spiralsnodd par, en isolasjonskappe som omgir det snodde lederpar, og en strekklastbærer som omgir isolasjonskappen, idet lastbæreren omfatter en kappe av strekklastbærende filamenter.A well logging device is provided which has well data collected by a downhole sensor transmitted to the surface via complementary modems, and transported to the surface modem via a data transmission cable connecting the modems to each other, the cable having at least one pair of insulated conductors wound as a main spiral twisted pair, an insulating sheath surrounding the twisted conductor pair, and a tensile load carrier surrounding the insulating sheath, the load carrier comprising a sheath of tensile load-bearing filaments.
