| 摘 要： | 苏里格气藏呈现出典型致密、非均质性等特点,给水平井的开发造成困难。为了提高气井单井产量及采收率,探索了一种简便实效的工作思路,通过对目标层段砂体分类统计、砂体规模刻画、砂体叠置规律探索,形成对不同砂体的水平井井轨迹设计。结果表明,苏里格苏东南区通过对水平井的差异化设计,有效的提高气井钻遇率及单井产量。

| Abstract: | Extremely tight, heterogeneous properties are all typical features of Sulige Gas Reservoir, which are also as difficulties for developing horizontal well. In order to effective enhance well production and gas recovery, a simple and effective working method was conducted via three steps, sand classified,sand scope described and sandstone superimposed structure cognized, in this paper. Finally work out different well path for target sand body in specific circumstance. Due to variable design of horizontal well, drilling effective rate and well production obviously increased. |
