| Abstract |
This study is concerned with an estimation of the productivity of the geothermal well. Steam and water flow rates under a fixed well head pressure of 8 ata are calculated for analytical well models by the equation dealing with performance of steam water two phase mixture flashing up in a vertical pipe. As the result, relationships between fluid pressure at the well inlet and the depth of the inlet, and between water flow rate and the depth of the inlet, with steam flow rates as a parameter, are obtained, and consequently, the minimum fluid pressure to obtain any quantity of steam flow rate correlative with the depth, and the upper limit of water flow rate, are calculated. |
