连续涡轮流量测井技术在商河地区的应用

Application of Continuous Turbine Flow Logging Technology in Shanghe Area

目前,地热井的产水段通常为500~2 000 m,产能测试通常采取常规的抽水试验来测试地下产能,该产能为井下总产能,无法获知各产层的产水能力,地热开采方式较为粗放。因此,文章提出了采用连续涡轮流量测井方法进行井下产能测试,明确各产层出水能力,由此确定合理的地热井井身结构和合理的产能,进而达到降本增效的目的,对下一步地热井合理开发具有相应的指导意义。

At present,the water production section of geothermal well is usually 500-2000 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.
