A man who repeatedly raped a woman he kept chained to the floor of a remote Victorian property after abducting her has been jailed for at least 19 years.

Michael Allen Pilgrim, 34, used disguises and fake identities to act out an abduction he planned over the 13 months he spent stalking his victim, stuffing her in a car boot and driving her to a property where he had purpose-built a sound proof "cubby house".

Victorian County Court Judge Michael Tinney said Pilgrim had engaged in "an incredible level of planning" that unmistakably spoke of an obsession with the 25-year-old victim he came to know when she was a sex worker.

"It is quite chilling to comprehend," Judge Tinney said.

He said the impact on the victim had been profound and it was not surprising she had thought she wouldn't survive.

He found Pilgrim showed no real or genuine remorse, but that he had an "odd personality" and was incapable of fully understanding the impact of his crime.

Pilgrim, of no fixed address, was on Tuesday sentenced to a total of 23 years and six months in prison with a non-parole period of 19 years.

He had pleaded pleaded guilty to a string of charges including four counts of rape, one count of false imprisonment, abduction and stalking.
