摘　　要：分注管柱密封状况直接决定注水质量和效果,验封技术是检验分注管柱质量的技术手段,并为上修作业提供依据。针对分注管柱验封困难及传统机械验封技术钢丝易被拉断、成功率低、验封效率低等问题,通过调研、研究及试验,形成了适用于大港油田分注管柱验封的电动验封技术。现场应用表明:该技术实现了密封胶筒电动坐封与解封、验封数据地面直读等功能,提高了验封的准确性及效率,成功率100%,能够满足分注管柱验封需要,已经成为大港油田分注管柱验封、确保分注合格率的主导配套技术,形成了分注管柱验封的新模式。The sealed condition of separate injection string decides the effect of separate injection. The sealing check technology is the technical means to test the quality of separate injection string, which provides the basis for operations. The mechanical sealing check technology for separate injection string has the issues like wire pulled off easily,low success rate,low efficiency and so on. Response to these problems,the electrical sealing check technology for separate injection string is studied. Through field testing applications, it is proven that the technology can achieve setting and releasing operations of the rubber electrically, reaching high accuracy, high efficiency and high success rate of 100%. The technology can meet the needs of the sealing check for separate injection string in Dagang oilfield, which becomes the governing supporting technology in a new model.
