In 1958, the first gas pipeline was installed in the Sichuan Basin; it was 20 kilometers long with a diameter of 159 millimeters, and it transported gas from the Huangguashan gas field in Yongchuan to the chemical plant in Yongchuan. In 1963, the Sichuan Petroleum Administration built the second gas pipeline in the country, transporting gas from Shigou in Baxian County to Chongqing. The pipeline had a diameter of 426 millimeters and a total length of 54.7 kilometers; it was the first pipeline to cross the Yangtze River. It marks the stage of development in supplying gas to industrial cities.
Yu Zong is really amazing – I corrected it right away without even verifying it first;P
In 1963, having just recovered from three years of natural disasters, it was no easy task to build a transmission pipeline over 50 kilometers long that even crossed the Yangtze River. I wonder what technology was used to build the pipeline crossing the Yangtze River back then? Should tunnels be dug manually or should the Yangtze River be blocked?
The one in Chongqing is the first pipeline to cross the river
The Yongchuan Chemical Plant and the Chongqing Chemical Plant no longer exist, right? Those two pipelines must have been taken out of use a long time ago as well
Well Huang 202H3-4 was spudded on July 24, 2019, and completed on February 1, 2020, at a total depth of 6,160 meters, with a horizontal section length of 1,502 meters. A \"high displacement + high intensity\" sanding technique was employed, in combination with a steering technology for temporarily plugging fractures, along with an integrated variable-viscosity fluid system to enable real-time optimization of the pumping procedures. A total of 24 fracturing stages were carried out, with an average sand volume per stage of 255.42 tons and an average sanding intensity of 4.08 tons per meter. The Huang 202H3 platform features a large scale of sand addition and a high amount of sand designed for each production stage. Southwest Oil & Gas Field Company strengthened technical support and quality control during construction, ensuring that wells 3 and 4 on the platform could complete their construction tasks successfully, with no equipment failures and at a rate of 3 production stages per day for most of the time.
Regroup and restore the glory of yesteryear
There was no “Chongqing Chemical Plant” back then; there was one in the 1980s, but it seemingly did not engage in chemical manufacturing
It should be the Chongqing Changshou Chemical Plant
