川东北地区高含H₂S，CO₂及复杂的地质和环境条件给勘探开发工程带来了世界级难题。通过引进攻关和实践，逐步形成了适合超深高酸性气田勘探开发的钻井、测试、生产完井等配套技术，实现了国内首个超深高酸整装普光气田的安全投产运行。笔者对川东北地区超深高酸性气田勘探开发工程技术进行了简要梳理，为国内同类气田勘探开发提供参考，并对超深高酸性气田的勘探开发工程技术发展提出了建议。

High H₂S and CO₂ content, complicated geological condition and field environment brings so many world-classic problems to the exploration and development engineering in Northeast Sichuan gas field. By introduction, research and practice, serial techniques such as drilling, gas test, and completion workover, etc., for the ultra deep and highly acidic gas field were gradually formed. Therefore Puguang Gas Field, for the first time, such reservoir is safely developed in China. This paper introduced these techniques briefly to provide reference for domestic similar gas fields and give many proposals to expand the exploration and development engineering techniques of ultra deep and highly acidic gas field.
