At present,the water production section of geothermal well is usually 500-2 000 m,capacity testing is usually done using conventional pumping tests to test underground capacity.This production capacity is the total downhole production capacity,and the water production capacity of each production zone cannot be known,so the geothermal exploitation method is relatively extensive.In this paper,the continuous turbine flow logging method is proposed to test downhole productivity.It is determine that water production capacity of each production zone,so as to determine the reasonable well structure and production capacity of geothermal well,and then achieve the purpose of cost decreasing and benefit increasing,and it is of guiding significance to reasonably develop geothermal well in the next step.
