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 sepa-rate 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 sepa-rate injection string in Dagang oilfield,which becomes the governing supporting technology in a new model.
