长庆气田地面工程技术现状介绍

PRESENT SITUATION AND ENVISAGEMENT OF THE SURFACE ENGINEERING IN CHANGQINGGAS FIELD

中国长庆气田所生产的商品天然气主要输往北京、天津、西安、石家庄、银川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。长庆气田主要包括靖边、榆林、乌审旗及苏里格等气田 ,其中靖边气田已建成产气规模 34× 10 8m3 /a。在简述了长庆气田主要基础条件诸如天然气性质、单井配产及地面自然条件等之后 ,着重介绍了具有长庆气田特点的地面工程技术现状及今后发展设想 ,其中包括高压集气、脱硫脱碳、酸气处理、低温分离及其他配套的小型发电、甲醇集中回收技术 ,以及今后回收CO2 的初步想法等。

Being taken as domestic gas and partially as industrial gas (e. g. power generation, synthetic methanol), etc., the marketable natural gas produced from Changqing Gas Field is mainly transported to the following cities as Beijing, Tianjin, Shijiazhuang and Yinchuan, etc. Changqing Gas Field is mainly composed of Jingbian, Yulin, Wushen Banner and Sulige gas fields, in which a scale of 3400 × 106m3/d has been built up in Jingbian gas field. Affer the principal basic circumstances, such as gas property, individual-well proration and natural condition, in Changqing Gas Field are simply stated, the present situation and envisagement of the surface engineering, including high pressure gas gathering, desulfurization, decarbonization, sour gas treatment, cryogenic separation and the other necessary small-size power-generating and methanol centralized recovery techniques, as well as a primary idea of recovering CO2 in the future, etc., in Changqing Gas Field are emphatically introduced in the paper.
