Weihai Introduces Insufficient Gas Sources for Gasification in West China

The reporter recently learned from Weihai's gas-fired heating department that the various constructions of the Weihai section of CNPC's Taiqingwei Natural Gas Main Line will be basically completed by the end of June. Weihai is expected to use natural gas from western regions such as Xinjiang and even foreign countries in the future, and new natural gas can be added each year. Supply 180 million cubic meters, so as to resolve the problem of inadequate air supply in Weihai. Coupled with Weihai's existing CNOOC Yanwei long-distance transmission pipeline, CNOOC and PetroChina's "double gas source" two pipelines will add "double insurance" to Weihai's natural gas supply.

PetroChina Wangjing Distribution Station has production conditions

On the 22nd, the reporter went to the Wangyu substation of PetroChina’s Taiqingwei Line in Diwentou Village, Wangjing Town, Lingang District. The gas pipelines were seen in the station and construction workers were doing anti-corrosion treatment and anti-corrosion coating for the pipeline. Apply bare yellow color to the exposed pipes to distinguish them. A person in charge of construction told the reporter that the pipeline painting work they performed was the final construction process and could be completed in the last few days.

The reporter also saw a specially designed nozzle at the site. It is understood that this nozzle is reserved for the pipeline access of Weihai Haihua Gas Company. The high-pressure natural gas pipeline accessed by Hong Kong and China Gas requires the connection of a gate station. In order to achieve the purpose of transportation, the gate station is currently under planning and construction. Natural gas distribution stations are generally built on long-distance pipelines. After natural gas transported by long-distance pipelines arrives at the distribution station, they are sent to the city gas pipeline network through the gate station after purification, metering, pressure regulation, and distribution processes.

The reporter learned from the manager of the PetroChina Shandong Natural Gas Pipeline Co., Ltd., responsible for the construction of the Wangyu substation, that the substation has started construction in 2011. At present, various construction projects have been basically completed and the equipment has been installed. In addition, the gas pipelines from Yantai to Weihai have also passed ventilation, pressure, and test tubes. At present, the depot has already been put into production conditions.

It is understood that PetroChina Wangjiao Gas Transmission Station is part of the second phase of PetroChina's Taiqingwei Natural Gas Main Line Project. It mainly realizes the gas transmission in Qingdao, Yantai and Weihai. At present, there are two pipelines in Yantai Laiyang District that are not yet connected. During the period, the distribution and distribution pipelines for all cities across the country have basically ended.

In a place less than two kilometers away from the Wangjiao substation of CNPC's Taiqingwei Line, Weihai Huajia Gas's construction team is laying gas pipelines. After the high-pressure natural gas arrives at the distribution station, it needs to be piped to the gate station for voltage regulation and then transferred to the city gas pipeline network. The construction of the gas pipelines now undertaken by the Hong Kong and China Gas Company is to “pave the bridge” for this purpose.

“Our project started construction in October last year, mainly to build a 7.5-kilometer high-pressure pipeline and gate station from the station to the gate station to the 11.5-kilometer-long secondary high-pressure pipeline of the supervisory network. In order to connect CNPC’s natural gas to the gate” We need to build a total of 19 kilometers of gas pipelines,” said Qu Yunlong, head of the engineering department of Ganghua Gas. As of now, there are only less than 500 meters of pipeline laying. It is expected that the entire project will be completed by the end of June. It marks the basic completion of various construction projects in the Weihai section of CNPC's Taiqingwei Natural Gas Line.

The reporter learned that with the 19-kilometer gas pipeline built by Hong Kong and China Gas, natural gas from PetroChina will enter the urban natural gas pipeline network to meet the gas demand in Weihai city. At the same time, Beijing Gas Company also plans to build a gas pipeline in Gejia Town, Wendeng District, and introduce natural gas from PetroChina. This pipeline will connect the gas pipelines from Rushan to Shidao in the Beijing Gas Company to meet the needs of Wendeng, Rongcheng and Rushan. Gas needs. Beijing Gas Company's gas pipeline construction project is planned to start next year.

Annual increase of natural gas supply 180 million cubic meters

At present, the city mainly relies on the CNOOC Yanwei long-distance transmission pipeline to deliver natural gas to urban areas, and its annual gas supply is less than 100 million cubic meters. The reporter learned from Weihai Huaji Gas Company that after the Weihai section of CNPC's Taiqingwei Natural Gas Line was put into use, it could provide 180 million cubic meters of natural gas per year.

"At present, there are 380,000 natural gas users in Weihai and more than 1,300 industrial and commercial households. Hong Kong and China Gas has an annual average gas supply of 90 million cubic meters, and Beijing Gas has a supply of 40 million cubic meters." The relevant person in charge of the gas department of the Heating Department told the reporter that from the current situation, CNOOC's offshore gas supply alone cannot meet the city's gas demand, especially in the winter, when natural gas is in short supply, it is often necessary to adopt “limited industrial Measures to protect civilian use have restricted the economic development of our city.

The reporter learned that, in addition to the impact on existing users, the shortage of natural gas sources has also made some projects that rely on natural gas for energy development slow, such as the use of natural gas for vehicles, etc., due to the lack of construction of natural gas filling stations, making this industry The current development is slow. The person in charge of the city's gas heating department said that after the operation of the Weihai section of CNPC's Taiqingwei Natural Gas Main Line, the initial plan is to provide an agreement to provide 180 million cubic meters of natural gas per year to meet the city's needs. With CNOOC and PetroChina’s “double gas sources” as security, the problems of natural gas energy development in our city will be completely solved.
