Study on Construction Technology of Geothermal Well in Bazhou, Hebei Province
Jiangsu Drilling Company of Sinopec Huadong Oilfield Service Corporation, Yangzhou 225261, China
| Abstract: | Being a kind of valuable natural resource, geothermal energy is both renewable and environmental friendly. Being a kind of widely distributed clean renewable energy source with huge reserves, geothermal resource will play an increasingly important role in energy consumption market. In recent yeas, the government has attached great importance to the development and utilization of new and renewable energy. The development of geothermal resources has important practical significance for alleviating energy stress, adjusting energy consumption structure, improving environmental quality, and accelerating the development process of cities. The urban area of Bazhou city is one of the areas with abundant geothermal resources in North China In 2007, Bazhou was successfully declared as the hometown of Hot spring in China, which will further promote the Expansion of the development scale and improvement of the utilization level of geothermal resources in this region. Geothermal team 1 has successfully constructed 3 geothermal Wells in Bazhon region and achieved good application Results. During the construction, the drilling technology and technological process of geothermal Wells were summarized by tire drilling team, hoping to provide reference and guidance for subsequent construction Wells and achieve the purpose of providing company with high-quality well bore. At the same time, it can help improve the supply capacity of clean energy, which is of great strategic significance for improving energy structure, alleviating energy shortages, protecting the ecological environment, and promoting carbon peak and carbon neutrality. |
