位于青海的柴达木盆地气候恶劣,却有着世界海拔最高的天然气井。截至今天,这里仍在延伸着世界上海拔最高天然气管道的纪录。柴达木盆地气田的气水关系复杂,气田岩性储层容易出砂,冬夏两季产量相差很大,地层压力又逐年下降。这一切增加了气田高产和稳产的难度。2010年,青海油田生产天然气57×108
The Qaidam Basin, located in Qinghai Province, has a poor climate but has the highest natural gas well in the world. As of today, there is still the world’s highest elevation of natural gas pipeline records. The relationship between gas and water in the Qaidam Basin is complex, and the lithologic reservoirs in the gas field are prone to sand production. The yield of winter and summer seams varies greatly, and the formation pressure drops again. All of this has increased the difficulty of high yield and stable production in the gas field. In 2010, Qinghai Oilfield produced 57 × 108 natural gas
