Abstract:For the purposes of offshore broken horizontal wells,leakage detection and bridging work is more difficult than conventional vertical wells. Based on the distinguishing feature of easing structures inhorizontal wells,related string and technology of leakage detection and bridging issummed up by comparative analysis both home and abroad. The results show t:hat the mechanical method and logging method is the main method to leakage detection and bridging in offshore hori- zontal wells. Introduced are the principles , operation procedures and detailed design of strings, based on the development technique and platform situation of the horizontal wells. The results can provide a scientific basis for the design and operation of leakage detection and bridging for the off- shore horizontal wells,and also an achievement of stable and long-term development of offshore horizontal wells.
Keywords:horizontal wells  leakage detection  leakage bridging
