摘    要:在油气采收过程中,水平井比直井更容易出现产出液含水率过高的现象。水平井在低渗透率油气田开发中的应用越来越普及,而针对水平井的特点,成熟的堵水方法和技术较少。通过对具有代表性的岩样进行气润湿反转实验,确定适用的气润湿反转化学剂,并对其进行热稳定性及地层配伍性实验评价,建立可视水平井堵水物理模型,进行气润湿反转剂使用前后的对比实验研究,得到水侵量、水侵速度及含水率的变化特征曲线。研究表明,气润湿反转剂堵水技术可用于水平井,可延缓见水时间,提高无水采收率,降低含水率。

Abstract:The phenomenon of excessive water production in the horizontal well is more than that in vertical well.Horizontal well is becoming universalized in the low-permeability oil and gas field development,but there are few water shutoff methods and techniques aimed at horizontal wells.By conducting the wetting transition experiment to typical rock sample,the applicable chemical gas wetting transition agent is determined and the thermal stability and formation compatibility are studied.The visual physical model of...
Keywords:horizontal well  wetting transition  water shutoff  water cut
