摘　　要：试油静温数据是含油气区地温场研究的主要依据之一,但有些油层的静温数据不准确。选取了东营凹陷150口井的静温数据进行精度分析,指出精度较低的静温数据不符合传导型地温场的特征;导致静温数据精度较低的主要原因是静井时间较短,此外油层改造、地下水活动及注水和采油也会对其产生影响。Static temperature data were the basis of studying geothermal field in petroliferous province,however,not all the static temperature data could reflect the original reservoir temperature conditions,some data were high deviational.This study selects static temperature data of 150 wells in Dongying Depression to analyze their accuracies.The results show that low accuracy data fail to match the characteristics of conductive geothermal field.The main reason for these mis-matchings is the relative short time of static wells.Besides,the accuracy is also affected by reservoir reconstruction,groundwater activity and water flood recovery.
