Research and analysis of directional drilling technology for long-distance pipeline crossings

This study focuses on the directional drilling technology for long-distance pipeline crossings. Taking a certain long-distance pipeline directional drilling crossing project in China as an example, the construction process of directional drilling crossing is analyzed. Based on this, the key points of directional drilling technology for long-distance pipelines are summarized. Finally, reasonable solutions are proposed for the deviation problem of directional drilling during the crossing process. This lays the foundation for further development in the field of directional drilling for long-distance pipeline crossings. The research indicates that the long-distance pipeline directional drilling crossing project can be divided into three stages: pre-construction preparation, directional drilling operation, and subsequent finishing. Prefabrication technology, pipeline welding, and mud treatment are among the key points of directional drilling crossing. In order to prevent the deviation of directional drilling, various effective measures need to be taken, such as ensuring that the drilling rig is positioned to coincide with the centerline of the designed pipeline, using artificial magnetic fields, and strengthening quality control from multiple perspectives. This ensures the high-quality completion of long-distance pipeline directional drilling crossing operations.
