普光高含硫气田完井工艺技术研究与应用

Well completion technology in high sulphur-bearing Puguang Gas Field

普光气田属于高含H2S和CO2的碳酸盐岩酸性气田。由于H2S气体的剧毒性及H2S和CO2对钢材的强腐蚀性等问题,对该气田的采气工艺技术提出了更高的安全、防腐要求。针对酸性气田开采工艺进行了深入研究,对工艺成果进行了现场推广应用,取得了显著的经济效益和社会效益,为普光气田的顺利、高效投产奠定了坚实的技术基础。

Puguang Gas Field is a high hydrogen sulphide and carbon dioxide carbonate gas field. Because of the hypertoxicity of H2S, high corrosion of H2S and CO2 to steels, higher safety and anticorrosion requirements to the gas production technology in this field have been raised. A thorough study on acidic gas field production technologies has been made in this paper, and certain result has been obtained on completion technology, which is made wide field application and remarkable economic, and social benefit has been obtained. It laid a solid technical basis for the smooth and efficient gas production in Puguang Gas Field.
