【摘要】：南海琼东南盆地崖城13-1气田为我国海上第一个高产大气田,气田见水后产量下降幅度较大,迫切需要进行剩余潜力评价和综合治水措施研究。通过创新的水侵剩余气柱高度评价技术、水侵气藏动储量评价及水体活跃程度判别技术等水侵宏观评价技术研究,结果表明崖城13-1气田仍有较大的剩余潜力和治水需求。在此基础上,通过见水井携液影响因素分析和综合堵水层位确定等技术,采取降压生产和更换小直径油管排水采气、堵水及补孔等综合治水措施,提高了单井产能,有效地减缓了气田产量递减,预计可累增气25亿m3左右,极大地稳定了下游用气信心。本文研究结果对海上气田水侵气藏剩余潜力评价和治水措施决策具有重要的借鉴意义。
[Abstract]:Yacheng 13-1 gas field in Qiongdongnan basin of the South China Sea is the first high-yielding atmospheric field in China, and the output of the gas field decreases greatly after water treatment. Therefore, it is urgent to study the residual potential evaluation and comprehensive water control measures. Through the research of the innovative water invasion residual gas column height evaluation technology, the water invasion gas reservoir dynamic reserve evaluation and the water body active degree discrimination technology and so on water invasion macroscopic appraisal technology research, the result indicated that Yacheng 13-1 gas field still has the bigger residual potential and the water control demand. On this basis, through the analysis of the influencing factors of liquid carrying in water wells and the determination of comprehensive water shutoff layer, the production and replacement of small diameter tubing drainage gas recovery, water shutoff and filling holes are adopted to improve the production capacity of single well. It can effectively slow down the decline of gas production and increase the gas accumulation by about 2.5 billion m ~ 3, which greatly stabilizes the confidence of the downstream gas consumption. The results of this paper are of great significance for the evaluation of residual potential of water invasion gas reservoirs in offshore gas fields and the decision of water control measures.
