二氧化碳气压力能和自然冷量利用的研究

为了便于贮存和运输，需将二氧化碳气在一定温度和压力下，进行液化。通过对吉林万金塔地区地下二氧化碳资源的组分，各井井底静压、流压、静温、流温及不同季节不同深度地下温度等因素的研究，制定出了充分合理利用二氧化碳气压力能和自然冷量方案，并于2002年初应用到吉林石油集团3t／h液化二氧化碳装置上，已取得了明显经济效益。这一技术属国内首创，即将推广应用到新开发研制的3万t／a高纯二氧化碳液化装置上，每年可增加近1万t工业级液体二氧化碳产品，可获得可观的经济效益。

The Study of the Pressure Energy of Carbon Dioxide and Natural Cooling Utilization

Factors,such as components of carbon dioxide from WanJinTa Reservoir in Jilin,static or flowing bottom hole pressure,static or flowing bottom hole temperature and formation temperature at different depth in different seasons,have been studied in this paper.Schemes are developed to utilize the pressure energy of carbon dioxide and natural cooling.This technology is the first one put forward at home.It will be applied to the newly developed equipment that can purify carbon dioxide 30 000 tons per year,which can increase carbon dioxide production by 10 000 tons per year and lead to large economic benefit.
