[0079] Taking Gulu high-temperature geothermal wells as an example, a shallow hole reinforcement method suitable for high-temperature geothermal wells is provided, which specifically includes the following steps:
[0080] The construction of Gulu ZK101 well will take place from September to October 2020. It is located in the thermal display area of the geothermal field. There are vents, boiling springs, and hot springs within 50m around the geothermal well. During the construction of the geothermal well, the spring water 30m away from the wellhead Cloudiness occurs. The Gulu geothermal field is located in the Naqu-Yangbajing geothermal zone, and the main thermal structure is 20° northeast in this area. The 0-60m of the well is Quanhua, and the 65-70m is the weathered shell type shallow high-temperature heat storage. During the well completion test blowout process, if the blowout time exceeds 5 minutes, a large amount of water vapor gushes out around the wellhead, which affec...
