"Thrilled to be a Jet for 6 more years," Wheeler wrote on his verified Twitter account.
The sides were scheduled for an arbitration hearing Monday.
"Blake is very comfortable with the direction [general manager Kevin Cheveldayoff], ownership and his staff is taking the organization," agent Matt Keator told the Winnipeg Sun.
Wheeler, 26, had 41 points (19 goals) in 48 games last season. He led the team in goals and was second in points (Andrew Ladd, 46).
Wheeler has played 372 NHL games with the Boston Bruins, Atlanta Thrashers and Winnipeg, with 232 points (93 goals).
He was chosen by the Phoenix Coyotes in the first round (No. 5) in the 2004 NHL Draft.
Monday, the Jets and forward Bryan Little agreed to terms on a five-year, $23.5 million contract, also avoiding arbitration.
"It's a very good core that will keep growing together in the years to come," Keator told the newspaper.
