摘　　要：塔里木盆地大宛齐地区含油构造埋藏浅 ,一般不超过 80 0 m,完井后大多需要 139.7mm套管测试。针对浅井套管测试封隔器密封困难且易提松、测试阀不易打开、抽汲作业时方余选择困难等测试难点 ,采用了 70 # - 70 # - 70 # 胶筒组合、 4 .4 mm剪销、A3封隔器、混合液压油及合理的方余计算方法等改进措施 。The oil bearing structure in Dawanqi Area of Tarim Basin is shallow with buried depth,generally no deeper than800m, most of these wells need drillstem test in 139. 7mm casing after well completion. In connection withdifficult seal and easily picked up loosen of the packer, tester valve not easy to be opened,difficult kelly-upselection while swabbing and other difficult points for shallow cased hole test, the utilization of 70#-70#-70#packer element combination, 4. 4mm shear pin, A3 packer, mixed hydraulic fluid, reasonable kelly-upcalculation approach and other improvements has obtained good application results.
