Patent EP-0045420-A1 (EP)
Inventor: SANTANGELO JOSEPH GERMANO
IPC: E21B43/243
Filed: 1981-07-17
Abstract: In an injection well for underground gasification of carbonaceous materials, either liquids or solids, by partial combustion with oxygen-rich gas in the presence of a moderating fluid such as steam, air, C0 2  or the like, in which the moderating fluid is introduced through an annular path (16) surrounding the injection tube (14) through which the oxygen-rich gas is injected, back flow of gasification products from the well is prevented by providing a flow restriction (18) in the annular path (16) to increase the linear flow velocity of the moderating fluid while maintaining the designed mass flow rate of said moderating fluid. The flow restriction (18) is so designed that the downward flow velocity of said moderating fluid downstream of the restriction corresponds to the formula:     wherein g is the gravity constant, D is the diameter of the well casing (12) and y is greater than one.
