With the gradual fall of winter, the test of gas shortage is once again placed in front of the competent authorities and gas supply companies. The National Development and Reform Commission issued a notice on October 22, and it is expected that the supply and demand of natural gas in China will be tight in the winter and spring, and the contradiction during peak hours in parts of North China and Northwest China will be prominent. In the case of persistent low temperature weather, the situation will become more severe.
On the basis of requiring existing gas fields to maintain full-load production, the notice specifically mentions the need to make overall use of unconventional resources, including the adjacent grid connection of coalbed methane, and accelerate the development of shale gas.
China Petroleum Economics and Technology Research Institute previously released a report predicting that in 2014, China's natural gas production will be 132.5 billion cubic meters, imported natural gas 60 billion cubic meters, total supply of 192.5 billion cubic meters, while China's natural gas demand is 206.1 billion cubic meters, total The gap is 13.6 billion cubic meters.
This figure is much higher than the supply and demand gap of 6.7 billion cubic meters in 2013.
The National Development and Reform Commission previously announced the operation of natural gas in the first three quarters of 2014. In the first three quarters, the apparent consumption of natural gas in China was 129 billion cubic meters. In the same period, natural gas production was 93.2 billion cubic meters, and imports were 42.4 billion cubic meters. Among them, the import of pipeline gas increased significantly.
Despite the increase in production, the gap between apparent consumption and production is further widening from the data of the previous three quarters.
“In the past two years, China’s natural gas production has grown at an average annual rate of 8.4%, significantly lower than demand growth,†PetroChina’s analysis report said.
The NDRC requested in the notice to maintain the full production of the existing gas fields. Increase the development of major oil and gas fields such as Changqing, Tarim, Qinghai, Southwest, Daniudi, Liwan 3-1 and Dongfang 1-1, optimize mining plans and prevent gas well production from falling. In addition, we will actively promote the capacity building of the new areas such as Moxi, Yuanba and the middle and shallow layers in the southwestern region, strengthen the organization and management of the new wells, accelerate the trial gas and ground construction, ensure the timely access of the new wells to the gas collection pipelines, and strive to use the gas peaks. Before the arrival of the period, an effective supply capacity will be formed.
However, with the further increase in production and consumption, imports have become the main way to make up. The PetroChina report predicts that China's natural gas imports this year will be about 60 billion cubic meters. The National Development and Reform Commission (NDRC) requested that PetroChina strengthen its engagement with the resource countries of Central Asia, coordinate Uzbekistan to ensure the maximum amount of pipeline air intake, and Kazakhstan should reduce the download volume as much as possible, and strive to achieve a stable supply of imported pipeline gas.
The notice also specifically mentions the use of unconventional resources, including timely resolution of problems in the production and supply of coal-based gas in Inner Mongolia Datang and Xinjiang Qinghua, and strives for smooth operation. For coalbed methane resources that are not connected to the main pipeline network, it is necessary to join the nearest grid or participate in local security supply in the form of CNG (compressed natural gas) and LNG. In addition, efforts will be made to increase the construction of shale gas development projects such as Chongqing Fuling and Sichuan Changning-Weiyuan, and strive to increase the supply of unconventional natural gas.
The PetroChina report predicts that in 2014, the domestic natural gas production of 132.5 billion cubic meters, the conventional natural gas, shale gas, coalbed methane production totaled 131 billion cubic meters, coal gas 1.5 billion cubic meters. Recently, the reporter learned from PetroChina that the company has locked up three shale gas blocks in Changning, Weiyuan and Fushun-Yongchuan in the Sichuan Basin. Among them, Changning and Weiyuan production is expected to reach 1 billion cubic meters next year, and Fushun-Yongchuan will be 100 million cubic meters.
However, Wan Xuezhi, a researcher in the energy industry of China Investment Consulting, also told reporters that unconventional resources can only be used as a supplement to conventional natural gas, and can not exert much effect. The production and sales of coalbed methane, coal gas, shale gas and tight gas are There is a certain gap between industry expectations and industrial planning, which can only alleviate the gas shortage to some extent.
