摘　　要：流量测井目前在新疆地热勘查中应用较少,本次采用JDL-2W流量水位测井仪对AKT1进行流量测量,了解孔内地下水流速计算井内流量划分含水层位置;通过分析不同含水层流速数值正负变化,判断地层漏水,出水层位置;对比岩芯RQD值、数字测井数据分析流量测井对判断含水层位置的精确性;与周边地热井抽水试验数据对比地下水流速值,说明其准确性及可靠性;该成果将为温泉县地热资源储量计算提供科学依据。Flow logging is rarely used in geothermal exploration in Xinjiang.In this study,JDL-2 W flow of water level logging instrument was used to measure the flow of AKT1 to understand the water velocity in the borehole and calculate the flow in the well to divide the location of aquifer.By analyzing the positive and negative changes of velocity of different aquifers,the position of formation water leakage and water outlet layer can be determined.Comparing core RQD value and digital logging data to analyze the accuracy of flow logging in determining aquifer location;Comparing the groundwater velocity with the pumping test data of surrounding geothermal Wells,it shows its accuracy and reliability.The results will provide scientific basis for the calculation of geothermal resources reserves in Wenquan County.
