Well Sa-55

Well Sa-55, also called the Iron Man's First Oil Well, is a national cultural heritage site in the Yangshulin area of Jiefangnan Village, Honggang District, Daqing. The wellhead is surrounded by preserved drilling relics: the unloading pit, mud pool, earthen oil pool, duty hut and the workers' dugout. A Bei-Wu 40 drilling rig of the same model the team used stands west of the well, and the former site of the Wang Jinxi Memorial Hall and a stele forest lie to the east.

In March 1960 Wang Jinxi brought the 1262 drilling team from the Yumen oil field to the Songliao basin. Drilling of Sa 55 began on 14 April 1960 and reached a depth of 1,200.76 metres in five days and four hours. The well flowed from 25 May 1960 at 113 tonnes a day and produced for 49 years, yielding more than 150,000 tonnes in total.

The well holds special meaning for Daqing's people as a symbol of determination and industrial progress. Local stories celebrate the workers and technicians whose efforts made the oil discovery possible and shaped the region's identity.

The well site lies in the Yangshulin area of Jiefangnan Village, Honggang District, Daqing; city bus line 12 from the main bus terminal stops at Yangshulin. On the grounds you can still see the original unloading pit, mud pool, earthen oil pool, duty hut and the workers' dugout shelters, with a Bei-Wu 40 rig of the same type standing west of the well. East of the well are the former site of the Wang Jinxi memorial hall and a stele forest.

The well's original name, Sa 55, is rarely used today; it is known as Iron Man's First Well, a title tied to team leader Wang Jinxi. Landlady Zhao, seeing him work day and night without returning to eat, said she had never met such a driven man and called him a "iron man", giving the site its name.
