Hi,

I have a wallet paper with BIP38 and I write some word bad of the pass, I see this software: https://github.com/gurnec/btcrecover, but, what is the method to make bruteforce in a wallet paper?, thanks.

Please read this thread first:
https://bitcointalk.org/index.php?topic=1014202

It'll give you an idear of your odds in cracking said password. This thread even contains links to the brute force applications the followers of the thread used to try to crack the original password. IIRC, the tools on the thread were open source, so you can try to modify them to search for a single forgotten word instead of bruteforcing different letter combinations.

AFAIK, the tool you linked to is meanth to crack actual wallet files of different kinds of wallets, but not to crack bip38 passphrases.
