摘要:

 气体示踪技术是注气油藏现场动态监测的重要手段,已经成为混相驱油藏开发的重要组成部 分,但目前在气体示踪剂的筛选上,缺乏统一的筛选参数和筛选方法。通过对气体示踪剂 应 用效果及其影响因素的分析和对比研究,提出了7个筛选参数,并建立了基于模糊优选理论 和模糊层次分析法的混相驱气体示踪剂筛选模型,同时,以吐哈盆地葡北油田为例,对4种 常用的气 体示踪剂进行筛选排序和综合评。

关键词: 混相驱, 气体示踪剂, 筛选参数, 筛选模型

Abstract:

Gas tracer technology that is an important means to inspect the Gas injection re servoir's performance, has became a necessarily part of miscible flooding. Up to  now, there aren't uniform screening parameters and method to screen out the pot ential reservoirs. Based on the analysis and researches of the factors, which af fecting Gas injection miscible results, this article presents 7 parameters. By t he method of Fuzzy Optimum and FAHP (Fuzzy Analytical Hierarchy Process), the Mo del for gas tracer is successfully established. The new Screening Method is used  to screen and assess the 4 classical gas tracers in Pubei Oil Field. The result  shows that this method could perfectly evaluate and screen the optimal of the candidate gas tracer.

Key words: Miscible flooding, Gas tracer, Screening parameter, Scre ening model
