高升油田火驱井组火驱受效状况研究

Research on fire flooding effectiveness of fire flooding well group of Gaosheng oilfield

火驱过程中气体的受效方向是掌握火驱动态的重要途径。用模糊数学理论,以注气和产气相关数据为基础,建立了见气时间、见气幅度、沿途井相似程度和波动响应程度等评价指标,开展火驱受效状况研究。

The direction of gas effectiveness during fire flooding is an important means to master the fire performance.This paper utilizes the fuzzy mathematics theory and takes the relevant data on gas injection and gas production as the basis to carry out the research on fire flooding effectiveness and establish the evaluation indicators,such as gas breakthrough time,gas breakthrough range,the similarity degree with the wells along the flooding way and the response degree to fluctuation.
