Well Casing Heads, Systems, and Methods for Removing Fluid from Earth about an Underground Platform

摘要

Well casing heads are provided that can include: a housing defining a first opening at the first end and a second opening at the second end, the first diameter of the first opening being greater than the second diameter of the second opening; and at least one fluid passageway extending through a wall of the housing and into the second opening. Well casing systems within a wall of an underground platform are also provided. The systems can include: a well casing head; a pair of tubular members about each other extending from the well casing head into a wall of the platform; and a void between the two members, the void extending from within the underground platform to the at least one fluid passageway of the well casing head. Methods for removing fluid from earth about an underground platform are also provided.

1. A well casing head comprising:
a housing having housing walls extending between two ends, the housing defining a first opening at the first end and a second opening at the second end, the openings being in fluid communication with one another; the first opening extending through the housing and defining a first diameter in one cross section, the second opening extending through the housing and defining a second diameter in the one cross section, the first diameter being greater than the second diameter; and at least one fluid passageway extending through a wall of the housing and into the second opening.
