"bottom cellar" или просто "cellar", как вариант. см. определение здесь:
http://www.osha.gov/SLTC/etools/oilandgas/illustrated_glossary/cellar.html
"Cellar. A pit in the ground to provide additional height between the rig floor and the well head to accommodate the installation of blowout preventers, ratholes, mouseholes, and so forth. It also collects drainage water and other fluids for disposal."

"A rectangular pit, called a cellar, is dug around the location of the actual drilling hole. The cellar provides a work space around the hole, for the workers and drilling accessories."
