Abstract

In order to improve the connection rate between relief well and accident well

a transient electromagnetic（ TEM） array probe detecting method for relief well drilling in short distance is presented. Based on the array signal processing of the borehole TEM detecting system

combined with the symmetry of the proposed array probe Radon transform

where the relative attitudes between a relief well and a blowout well can be determined within the detection range. Simulation experiment results demonstrate the effectiveness of the proposed method for improving detection performance in short distance

identify relative attitude of accident well and relief well

offer significant information for the tracing phase of relief well.
