Another big step forward in the construction of natural gas pipeline network in Jiangxi Province

Another big step forward in the construction of natural gas pipeline network in Jiangxi Province (Reporter Du Jincun and intern Hong Jianghua) On the 1st day of the month, at the construction site of the first phase of the provincial natural gas pipeline network from Fengcheng to Yingtan, the machine roared. The construction personnel are carrying out the finishing work of the Ganjiang directional drilling crossing project. According to the staff of the Provincial Natural Gas Co., Ltd., the Ganjiang directional drilling crossing project of the first phase of the provincial natural gas pipeline network (Fengcheng-Yingtan section), which lasted for months, was completed in Fengcheng. Breaking the longest record of Sinopec's horizontal rock layer length (the original record is meters), creating conditions for the early realization of the supply of pipeline natural gas to Fuzhou and other places, and laying the foundation for the completion of the provincial-level natural gas pipeline network around Poyang Lake this year.了基。 The foundation.　　 It is reported that compared with other current projects, this project presents three characteristics: namely, the length of the traversal * long. The entry point for the Ganjiang directional drilling crossing was located in Tugboat Town, Fengcheng City, and the excavation point was located in Quangang Town, Fengcheng City. The horizontal length of the crossing construction reached .m. The geological conditions * are complicated. The crossing project will pass through complex stratum such as gravel sand, sand pebbles and pebbles, argillaceous sandstone, sandstone, etc. The length of the horizontal crossing rock layer is up to meters. The crossing process technology is *advanced. In order to ensure the smooth completion of the crossing on schedule, the crossing project adopts domestic advanced directional drilling and docking technology, and two drilling rigs carry out simultaneous construction operations at the entry point and the excavation point respectively.
