Recently, Sinopec’s first geothermal scientific exploration well, Well Fushenre 1, led by the Sinopec Petroleum Exploration and Development Research Institute, was drilled in Haikou. The successful implementation of this well will help to explore the potential of Hainan's geothermal resources, improve the level of geothermal resource exploration and development in Hainan Province, and lead my country's medium-deep geothermal resource exploration and development technology to the forefront of the world.
At present, the development and utilization of geothermal resources in my country is mainly in shallow layers. The Fushenre 1 well drilled this time is my country's first deep high-temperature geothermal exploration well with a depth of 5,000 meters.
In view of the problems such as strong abrasiveness of the formation in Well Fushenre 1, high temperature of the target layer, and many water layers encountered during drilling, the research team used the "dual-drive drilling + high-pressure jet" drilling technology and selected The integrated composite impactor speed-increasing tool improves the mechanical penetration rate, strengthens sealing, collapse and leakage prevention, selects high-temperature resistant instruments and tools, and does a good job in preventing collapse and sticking and leakage to ensure that no noise, cuttings, etc. are generated during the drilling process. pollute.
After the drilling is carried out, the formation and enrichment mechanism of deep geothermal in the Fushan Sag will be revealed based on detailed rock core, logging and other data, and the key technologies for deep geothermal detection and evaluation will be verified to help promote deep geothermal development. Large-scale development of resources.
