![]() ![]() Drilling failures and complications, which often accompany the application of the HDD technology, result from poor design of the well path in relation to the existing geological and drilling conditions. The effectiveness of HDD technology application is mostly determined by its properly designed trajectory. Horizontal Directional Drilling (HDD) is one of the most popular trenchless technologies. In order to build new pipeline networks, dig and no-dig techniques are used. Underground pipe installations are used in the energy sector, gas industry, telecommunications, water and sewage transport, heating, chemical industry, and environmental engineering. The results show that the IRMO algorithm has a great potential for automatically designing and optimizing preliminary drilling paths with low time-consumption and high feasibility.Īdvances in the field of material engineering, computerization, automation, and equipment miniaturization enable modernization of the existing technologies and development of new solutions for construction, inspection, and renovation of underground pipelines. Two different examples were tested in different scenarios, theoretical and practical. Drilling mud pressure was considered in the processes of the mechanical design to avoid collapse or possible instability. In this study, five-segment trajectories were combined with the catenary trajectory to utilize their advantages using the improved radial movement optimization (IRMO) algorithm. However, it is difficult to be implemented with technology limitations due to its continuously changing curvature. ![]() The catenary method was proposed to design the drilling path with the advantage of lower friction for the mechanical constraints. Alternating straight and curvilinear segments is a commonly used method for designing drilling paths, especially the “straight-curvilinear-horizontal straight-curvilinear-straight” five-segment arrangement. This study aimed to propose and test a method to predesign and optimize the drilling paths automatically, with the view of improving the efficiency of HDD design preparations. In practice, the drilling path of horizontal directional drilling (HDD) projects is usually constructed by trial and error based on a preliminary designing trajectory. Therefore, it should be used in industrial practice as an alternative to current designing methods. According to the authors, due to natural stress distribution, the catenary method allows the use of smaller pulling forces during installation and ensures longer pipeline life. ![]() Applicable formulas and computational algorithms have been given, together with a computational example which enables comparison of the classical design methodology with the new one. Then, the original catenary method is proposed, taking into account natural deflection of casing pipes. A review of the trajectories used so far has been provided, offering calculation algorithms to determine their well path. The aim of this article is to present a new approach in the design of HDD trajectories in two–dimensional space (2D). Horizontal Directional Drilling is one of the most popular trenchless technologies. Therefore, it is necessary to build new pipelines networks using dig and no–dig techniques. Also, in Poland in recent years there has been a significant increase in natural gas consumption. An increase in demand for energy natural resources has stimulated the development of gas pipeline networks in Europe, as well as globally.
