摘　　要：随着青海油田注水工艺技术的不断发展,原有的堵塞式双探头和载线式双压力验封测试技术,在桥式偏心和免投捞同心分注井验封测试中存在诸多不适用性,为此,研制了以电缆为载体的地面直读式验封仪。该验封仪采用地面控制、电动密封和实时监测的新技术,能够克服传统钢丝作业固有的井下测试、地面回放、数据分析、下井复测等工序导致的劳动强度大的弊端,降低了验封仪遇卡的概率。经油田先导性试验表明,其工作效率和验封一次成功率明显提高。Along with the development of injection technology in Qinghai oilfield,the original plugging type double probe and load line type double pressure test sealing technology has many inadaptability in the sealing test of bridge eccentric and free throw out of concentric separate injection,therefore,the ground direct reading test sealing apparatus with the carrier of cable is developed.For using some new technology of the ground control,electric seal and real-time monitoring,it can overcome the disadvantages of great labor intensity lead by tedious processes for traditional wire operation inherent down-hole testing,ground playback,data analysis,and down-hole complex measured,which reduces stuck accident ratio of seal checking apparatus.By piloting test in oilfield,it shows that work efficiency and the test recto time success rate can be obviously improved.
