摘要
由于初期工作制度不稳定,造成胜坨油田沙一段边水气藏过早局部水淹。在综合分析的基础上,提出了利用水平井开发剩余气的调整挖潜方案,利用SimBestⅡ扩展黑油软件,研究了不同布井方式的开发效果。研究表明:水平段长度为250m的老井侧钻水平井方案为最佳开采方式,对同类型气藏的开发具有借鉴意义。
Initial unstable working system had resulted in locally watered out in Es, gas reservoir with edge water of Shengtuo oilfield. On the basis of comprehensive analysis, potential-tapping program is put forward using horizontal well to exploit the remaining gas. Development results of various well patterns are studied using extended Black Oil software SimBest Ⅱ . The research indicates that side-track horizontal well with horizontal length equal 250 meters is optimum, which can provide successful experiences for similar type of reservoirs.
