I think there is a strong possibility J-11D can be mass produced. Depending on J-20 price and required number of airframes PLAAF envision in 2030s, continued J-11 production can be an option. Especially, if they are not planning significant upgrades with the current J-11 airframes.
The PLA will certainly continue producing and procuring modern Flankers between now and the mid to late 2020s -- but I'm not sure whether they need to buy J-11Ds.
I expect that they will likely just continue buying J-16s instead, as well as of course using some Flanker slots to buy advanced J-15 variants, and both J-16D and J-15D.
The J-11D as an aircraft logically shouldn't offer any particularly unique capabilities that cannot be integrated into continued new batch J-16 production or J-11BG MLUs, going into 2030s.
By the time 2030 comes around, I would be surprised if they were still needing to build Flankers -- by 2030 I would expect the PLA's new build fighter aircraft would all be 5th generation, a combination of J-20, carrier based J-XY, and perhaps a land based J-XY option.
The USAF benefits from buying a bunch of F-15EXs for their own unique reasons and because many of their original F-15s are so old, but the PLA doesn't really have that issue because the airframe life of J-11B aircraft are still quite young, most of them only turning 10 years old now, and because the PLA's equivalent of F-15EX is J-16 which remains in active production today.
