摘要:

目前烟道气辅助蒸汽辅助重力泄油(SAGD)技术已在机理研究和数值模拟方面取得了进展,但由于实际投入油田试验的操作成本较高以及存在额外的能量消耗,所以无法直接判断和验证实际应用效果。为了更全面地评估注采方案,本文运用模糊综合评价法建立了多元评价体系,以环境、能量、工艺、经济为4个评价指标,对不同注采方案进行综合评价以选出综合性能最优的生产设计方案,为实际生产方案的选取提供参考,首次对烟道气辅助SAGD实际工程进行评价研究。基于“有无对比法”,将烟道气辅助SAGD与常规SAGD进行对比,结果表明烟道气辅助SAGD的综合效益更好,佐证了烟道气辅助SAGD驱油的优越性。为方便工程应用,开发了“烟气辅助SAGD驱油评价软件”,通过软件进行实例分析并进行方法对比,验证了本文方法的有效性、适用性和准确性。

Abstract:

Flue gas-assisted SAGD has made advances in mechanism and numerical simulation. However, it is unable to judge and validate test results directly due to high operational costs and extra energy consumption in oilfield tests. In order to evaluate projects thoroughly, this paper establishes multiple evaluation systems of flue gas-assisted SAGD with a fuzzy comprehensive evaluation method, taking environment, energy, technology, and the economy as four evaluation indexes, and conducts a comprehensive evaluation to select the production scheme with the best comprehensive performance. The flue gas-assisted SAGD is evaluated for the first time, which provides references for actual production. Comparing flue gas-assisted SAGD with SAGD based on "With and Without Methods", the merits of flue gas-assisted SAGD are visible, which are superior to those of SAGD. In order to facilitate field applications, flue gas-assisted SAGD evaluation software is developed and compared with other methods. The feasibility, availability, and accuracy of the proposed method are verified.

Key words: flue gas-assisted SAGD, fuzzy comprehensive evaluation, With and Without Methods, petroleum, flue gas
