四川气田低产气井天然气开发方案研究

针对四川气田低产气井天然气未能开发利用的情况，提出了采用固体脱硫剂（ＳＤＡ）、变压吸附（ＰＳＡ）、吸附天然气（ＡＮＧ）和天然气汽车（ＮＧＶ）技术开发利用低产气井天然气的初步可行方案。通过分析、评价和对比，认为采用一套橇装式天然气净化、储运装置，将低产气井天然气就地净化、吸附后用钢瓶储运，可作为汽车燃料和家用燃料。尤其作为汽车燃料，具有巨大的经济效益、社会效益和环保效益。

Study of Development plan for Natural Gas of Strippled Wells in Sichuan Gas Fields ,

In view of the fact that the gas of the stripped wells has not been developed, this paper presents a preliminary feasibility plan of its development and utilization by adopting the techniques of solid desulfurizing agent(SDA), pressure swing absorption (PSA), absorption natural gas (ANG) and natural gas vehicle (NGV). Through analysis, evaluation and comparison, it is considered practical and feasible to store and transport the gas in steel cylinders after it is purged and absorbed by a skid-mounted gas purification plant. The gas can be used fuel for vehicles and in daily life, and as a fuel of vehicles, it has great benefiits in economy, society, and environmental protection.
