从1989年发现陕参1井至今，长庆气田经历了15年的勘探开发与地面工程建设。截至目前，已累计销售天然气120×108m3，主要输往北京、天津、西安、石家庄、银川及“西气东输”下游的上海、苏州、郑州等城市作为民用燃气，部分用于发电和化工原料（例如合成甲醇）等。文章根据长庆气田靖边、榆林、苏里格等气区中天然气生产规模、温度、压力、气体组成等特点，分别介绍了这些气区的天然气净化情况，其中着重介绍了靖边气区天然气净化中的脱硫脱碳、酸气处理和配套工艺技术。

INTRODUCE OF GAS PURIFICATION TECHNIQUES IN CHANGQING GAS FIELD 1)

Changqing gas field has experienced 15 years’ exploration, production and surface engineering construction since well Shaancen 1 was found in 1989. Up to now, 12×108m3/a of gas has been sold cumulatively. The gas is delivered to cities such as Beijing, Tianjing, Xi’an, Shijiazhuang, Yinchuan, and Shanghai, Suzhou, Zhengzhou etc. in the downstream areas of “West — East Gas Transmission” mainly as residential fuel and partly as feed materials for power generation and chemicals (e.g. methanol) etc. According to the features of gas scale, temperature, pressure, composition etc. in the gas producing areas of Qingbian, Yuling, Sulige etc. of Changqing gas field, the gas purification processes are introduced respectively for the areas. And the desulfuration, decarbonation, sour gas process, and the matching techniques are described in detail for the gas purification of Qingbian gas producing area.
