摘要
吉林油田营城组气藏气井高温高压高含CO2,井下工况恶劣。在生产过程中,部分气井出现了套压异常的现象,给安全生产构成严重威胁。通过对套压异常的原因探索性分析,初步形成了针对性的技术措施,经现场应用取得较好的效果,有效减少了气井由于管柱泄漏的修井作业次数,降低了安全风险。
The Yingcheng formation in Jilin Oilfield is characterized with high temperature & pressure,high content of carbon-dioxide,and the gas well's condition being bad seriously.The high annular casing pressure in parts of wells is high during producing procedure to bring risk seriously for safety production.By The further studying the reason of high annular casing pressure,the technical countermeasure is explored and experiment in field-test gets a good results,which effectively diminishes workover frequency because of leakage of string and reduces security risk.
