| 摘 要： | 多层测试井的产能劈分是油气藏勘探开发中的一个关键问题。影响产能的储层参数很多，不同的物性参数对储层产能影响的大小不同；模糊系统理论将综合评价的定性问题转化为定量问题，层次分析法将不同因素按照相关性大小计算其权值。利用综合评价系数对多层试气中的小层进行综合评判和优选，进而对产能进行合理劈分。给出了评价因素对等级区间隶属度的求取方法以及不同因素之间相对权值的计算方法。通过实例给出了模糊综合评判法进行产能劈分的原理和具体步骤，进一步验证了该方法在鄂尔多斯盆地苏里格气田的应用效果。

| Abstract: | Production dividing is a key issue in exploration and development of multi-layered oil and gas reservoirs of testing wells. There are many factors affecting the productivity of reservoir productivity, and the influences of physical parameters are different. The qualitative problem of comprehensive evaluation was transformed into quantitative problem by fuzzy system theory, and the weights of different factors were calculated by analytic hierarchy process according to different correlations. Small layers in multi-layered gas testing well were evaluated comprehensively and selected optimally based on comprehensive evaluation coefficient, and then the productivity of multi-layered gas reservoir was reasonably divided. The method of calculating membership of evaluation factors to grade intervals was given, and the calculation method of relative weight between different factors was put forward. Furthermore, principle and concrete steps of fuzzy comprehensive evaluation method for production dividing were proposed with the example. It is verified that the application of the method in Sulige oilfield of Ordos Basin is good. |
