The multifunctional deep geothermal resource drilling and completion experiment device is applicable to geothermal resource efficient development and equipment developmental researches, simple in structure, high inuniversality, high in safety, low in cost and suitable for being popularized and used.

Description

technical field [0001] The invention relates to the technical field of new energy production increase, in particular to a multifunctional deep geothermal resource drilling and completion experiment device. Background technique [0002] With the sustained and rapid growth of the national economy, my country's demand for energy is expanding day by day. At the same time, the problems of resource depletion and environmental pollution caused by traditional fossil energy have become increasingly prominent. As a clean and renewable energy with important application value and utilization potential, geothermal resources have huge reserves in my country, and are considered to be one of the important ways to realize the continuity of energy resources. [0003] my country's shallow geothermal resources below 200m are equivalent to 9.5 billion tons of standard coal. By the end of 2015, the heating / cooling area of ​​shallow geothermal energy in the country will reach 392 million square ...
