Recently, Kela Keshen Gas Area, the first trillion cubic meters gas area in the Tarim Basin, has exceeded the 200 billion cubic meters mark in terms of cumulative production of natural gas, providing a solid gas source guarantee for stable gas supply in the West East Gas Transmission Project, and effectively promoting China's green and low-carbon development.
Kela Keshen atmospheric region is located in the northern margin of Tarim Basin. As the main gas source of West East Gas Transmission, in recent years, Tarim Oilfield has found five gas reservoirs in Kela Keshen Gas Field, with a new gas production capacity of 5.65 billion cubic meters, which is equivalent to a new oil field with an annual output of 4.5 million tons.
It is understood that in 2022, Kela Oil and Gas Development Department will produce more than 13 billion cubic meters of natural gas, providing clean energy guarantee for more than 160 cities, more than 3000 large and medium-sized enterprises, and 400 million people in the western, central and eastern regions of China.
The underground structure of Kela Keshen atmospheric area is complex, and the buried depth of gas reservoir reaches 4500 meters to 8100 meters. This area is not only a "life restricted area", but also a "exploration restricted area". Through basic geological theory innovation and engineering technology breakthrough, Tarim Oilfield has developed the first ultra deep clastic rock gas field with an annual output of 10 billion m3 in China - Keshen Gas Field, the deepest onshore gas field in China - Keshen 9 Gas Field and other deep development landmark gas fields, and improved the deep development technology system.
It is understood that the chemical scale removal and blockage removal technology has been innovated, which has successfully increased the production of natural gas by 7.489 billion cubic meters. This technology has authorized 7 national invention patents, completed the construction of intellectual property rights group, and added a sharp tool to ensure the stable gas supply of the West East Gas Pipeline.Editor/Ma Xue
