This is just a starting point; we welcome everyone to participate more in discussions on this forum – the more people involved, the more lively it becomes. Haichuan becomes even better with you here. Replies are rewarded; feel free to discuss! ------------------------------------------------- The control project for Sihé Gas Company’s “New industrial gas pipeline network project in Fuling District”: successful directional drilling across the Wujiang River. At 21:00 on April 15th, the pipeline was successfully pulled back across the river from Group 3, Caichang Village, Jiangdong Sub-district, to Group 3, Shunjiang Village, Lizi Sub-district, as part of the directional drilling project across the Wujiang River. The two key milestones marking the \"Sihé Gas Company’s new industrial gas pipeline network project in Fuling\" – the crossing of the Wujiang River and the Liuxiangxi Creek – have been successfully completed, and this achievement also set a record as the first time that pipe pulling was successful in one go since the directional drilling across the Wujiang River. “The Wujiang directional drilling passage is 890.14 meters in length, and the geological conditions there are complex. Detailed surveys show that the strata through which the drill passes feature uneven hardness levels and extensive fractures. The passage axis passes through undisturbed fill soil and marly limestone, with thin layers or lenses of mudstone, sandstone, and limestone interbedded, which makes it highly prone to problems such as drill jamming, fluid leakage, and hole collapse. Since work began last December, the contractor, Shanghai Hexin Pipeline Engineering Company, relied on its advanced technical skills, extensive experience in directional drilling, and strict construction management to complete the pipeline pulling operation across the Wujiang River in just 4 months. The “Fuling New Industrial Gas Supply Project” that the company is investing in to develop is one of the key construction projects in Chongqing City and Fuling District for the years 2013 and 2014. The project will be built in two phases, with a total designed investment of 558 million yuan. The first phase involves pipeline designs covering a length of 96 kilometers; 4 transfer stations and 4 valve rooms are planned to be constructed, with completion targeted by the end of June this year ； The design length of the pipelines for the second phase is 30 kilometers, with completion planned by the end of this year. Upon completion, the project will have a gas supply capacity of 4 million cubic meters per day and a gas transmission capacity of 4 million cubic meters per day. It will play a positive role in meeting the natural gas needs of new industrial users in the Longqiao, Baitao, and Qingxi industrial parks, as well as in handling the transportation of shale gas from Jiaoshi.
