English translation:outer hanging leaching/solution-mining string
Explanation:
Подвесная колонна скважины - колонна труб, подвешенных на колонной головке скважины на период строительства и эксплуатации подземного резервуара; подразделяется на внешнюю и центральную. Внешняя подвесная колонна - подвесная колонна труб, находящаяся (как правило) между центральной подвесной и основной обсадной колоннами и предназначена для: подачи воды (противоточный режим) или отбора рассола (прямоточный режим) при строительстве выработки-емкости; закачки и отбора хранимого продукта при эксплуатации резервуара.

Hanging string - a concentric inner production casing or tubing hung from the wellhead and normally used to inject and withdraw gases or displace fluid into and out of the cavern.

"A well is drilled into a suitable salt formation and, after running and cementing the last casing, two concentric tubulars 'leaching strings' are run in the hole for the purposes of leaching the cavern. The annulus between the outer leaching string and the casing is filled with either a diesel or nitrogen blanket to prevent leaching of salt around and above the bottom of the casing (casing shoe). To dissolve a cavern in salt fresh water is circulated into the well through one of the leaching strings and higher density brine produced through the other leaching string."

Example sentence(s):
  • he joints of the outer hanging leaching string shall be gas tight so as toprevent the loss of the gaseous blanket
  • Underground storage caverns require a suspended casing, or hanging string, to extend into the bottom part of the cavern for brine injection in order to remove oil from the top of the cavern;
