What remains around a well
The heritage record names the working spaces associated with Songji No. 3: a duty room, earth shelter, water well, paraffin-removal room, mud pit and oil pool. These structures show a drilling site as a small operating system, with shelter, water and equipment care beside the bore. The site was listed as a national key cultural relic in 2001.
The core and the well site
Daqing’s oilfield history exhibition hall displays a core from Songji No. 3 among nationally designated first-grade cultural relics. The sample is preserved indoors; outdoors, the associated duty room, earth shelter, water well, paraffin-removal room, mud pit and oil pool mark the support system around the bore.
