摘要

The Iceland Deep Drilling Project passed a significant milestone in the geothermal industry when its IDDP-2 well at the Reykjanes Peninsula in Iceland reached the depth of 4,659 meters on the 25th of January 2017, after 168 days of drilling. The IDDP-2 achieved its initial targets, (a) to drill deep enough to reach supercritical conditions (4 to 5 km), (b) to measure the fluid temperature and pressure, (c) to search for permeability, and (d) to recover drill cores. After only 6 days of heating, the temperature measured at the bottom of the well was ~427℃, with fluid pressure of 340 bars, and indications of permeability at depth (Figure 1), and drill cores were retrieved. It's clear that the bottom of the well reached fluids at supercritical conditions, so that the main objective of the drilling phase of the project had been achieved.
