Description
Summary:The pre-installed optical fiber outside the casing poses a great challenge to the perforation operation. How to accurately determine the orientation of the fiber outside the casing, avoid the directional perforation with optical fiber outside the casing is an urgent problem in production. In order to solve this problem, introducing foreign magnetic orientation tool (MOT) and making adaptive improvements. This technology effectively solves the contradiction between avoiding the optical fiber outside the casing and improving the effective perforation sector, realizes the accurate measurement and control of perforation orientation, and provides high quality perforation technology for the gas reservoir development of Zhaotong shale gas block in Zhejiang oilfield.
