杭锦旗区块两种集气工艺的建设投资与成本分析

摘要

鄂尔多斯盆地北部气田主要应用两种集气工艺,分别是大牛地气田和靖边气田采用的高压集气工艺,以及苏里格气田采用的中(低)压集气工艺.针对这两种集气工艺的应用情况进行优缺点分析.以产能建设方案为例,从投资和成本的经济角度分析杭锦旗区块在不同集气工艺下的应用差异.最后确认中(低)压集气工艺更具经济优势.%At present,two gas gathering processes are mainly used in northern Ordos basin: the high pressure gas gathering process(widely used in Daniudi gas field and Jingbian gas field)and the medium(low)pressure gas gathering process(used in Sulige gas field). Based on the practical exploration and exploitation situation,this pa-per analyzes their advantages and disadvantages. A capacity building program is assumed to study the difference of the two gas gathering processes from two aspects of investment and cost in Hangjinqi area. Thus the medium(low) pressure gas gathering process is determined to have economic advantages in this area.
