| Summary: | The permanent optical fiber dynamic monitoring outside casing has become an important direction in the development of smart oilfields. As the key supporting content, the atraumatic fiber optic perforation technology is very important. Focusing on the requirements of atraumatic fiber optic perforation, this paper proposes a new atraumatic fiber optic perforation technology suitable for directional wells which combines magnetic orienting logging method with gyro directional perforation technology. Based on the detection and analysis of the gravity azimuth of the optical fiber fixator, the safe perforating orientation is designed. The support positioning device is combined with a zero-phase single-wing perforating gun equipped with a positioning guided fishing device to achieve atraumatic fiber optic perforation accurately. The application results in Changqing oilfield show that the atraumatic fiber optic perforation technology can safely be implemented in directional wells with inclination greater than 5°, and it has good reliability and is worth further popularization. |
