试井成果是油气田制定开发方案、措施选井及评估的重要依据, 但资料的多解性严重制约着试井成果的准确性和可靠性, 降低了使用价值。从产生试井资料多解性的来源入手, 通过实例分析试井设计、资料录取、模型选择(重点分析井筒、近井筒效应, 油气藏类型, 外边界)等因素对试井解释结果的影响, 确定有效排除试井成果多解性的原则和途径。

Well test results are very important foundation to draw up oil and gas field development scheme and choose and evaluate treating wells. But ambiguity of well test data restrained the accuracy and reliability of well test results so seriously as to lower their usefullness. Influences on well test results caused by well test design, data collection, model choosing (including wellbore, near wellbore effects, reservoir, outer boundary), and so on have been analyzed, and have been effectively determined.
