The Status, Development, and Key Technologies of Pipeline Directional Drill Project

Horizontal directional drilling technology is an important and very promising trenchless pipeline crossing technology. On the basis of the related literature research at home and abroad and the authors pipeline construction site investigation, pipeline directional drill project status, directional drilling theory research situation, horizontal directional drilling rig status, the major engineering construction application status and technical application are fully systematically analyzed. Urgent technical difficulties and existing measures of the pipeline directional drill project under the complex conditions (such as the complex formation lithology, the complex geostress, the large pore diameter, the long through distance and the higher environmental protection request) are analyzed and expounded, and the key technologies and the main problems of the pipeline directional drill project under the complicated condition are put forward. The technical features between the large displacement horizontal well drilling technique of the oil and gas exploitation and the pipeline directional drilling technology are systematically compared, and the thoughts of the oil and gas exploration highly-displacement horizontal drilling technology are expound and referenced for, then the technical difficulties solution methods and technology development direction of the pipeline directional drill project are determined.
