It is the maximum value to exploit and apply the geothermal resources. But it is often because of high production and sand rninflux that the geothermal well sets strict demand on the test technology, so it gets difficult construction and low success rnratio. Taking an Example from Well Li3, this paper analysed the success keys of testing in geothermal well and gave the rnmeasures of test technology appropriately.%地热资源具有极高的开采应用价值。但地热井多因产量高、易出砂对测试工艺要求高，rn施工难度大，成功率低。本文以李3井为例分析了地热井测试成功的关键，相应地提出了测试工艺rn措施。
