The Appraisal Of Water Discharge And Temperature Of Grand Canyon Geothermy Well Drilling Craft And Plan Of Geothermal Resource Drainage In Yunnan

This paper takes the Grand cannoy geothermal well in YunNan province as the research object. As he geothermal well Water volume and the water temperature is the most importance things of geothermal well develops. The discharge and the water temperature of the geothermal well directly affects the project quality, and geothermal well construction craft then directly decides the geothermal well the water temperature and discharge. Moreover, as a result of this project geographical position particularity: The Grand Canyon geothermal well will sink buries deeply in 90 meters submarine. Whether will the current this local geothermal resource preserve,whether will make the geothermal resource to other place developments, it will face the question also will be a question which the underground hot water development use needs to solve in our country at present. It need to make the science and correct recognizing.The key point of aticle is the geothermal well construction craft, adopts the technical measure to the geothermal well discharge influence, appraisal on geothermal resource drainage to higher place use. Therefore the geothermal well construction craft and plan of geothermal resource drainage to higher place use to the geothermal well discharge and the water temperature influence is a key point which this article analyzes.In the article has outlined the geological condition research of geothermal well area, investigates thoroughly the entire geothermic region the hydro geological conditions, Water - bearing stratum of the Grand Canyon geothermal well and the characteristic of space distribution, and prepares for the basic data for the water volume and temperature influence analysis. In the article has introduced the Grand Canyon geothermal well drilling craft, proposed the existence question. The measures to increase discharge considering construction craft and the stratum characteristic to the Grand Canyon geothermal well has made the analysis, The reasonable measures for increasing the discharge of deep geothermal wells have concluded and summarized under similar geology environment.This article uses the GEO-SLOPE software simulation to analyze the slope stability nearby the Grand Canyon geothermal well area; The establishment hydrology geology model, considering experiments result make the science analysis and the appraisal to the geothermal well discharge stable current capacity and the heat lost.
