摘　　要：针对气井压力测试对温度的敏感性,根据气体压力与温度的关系,建立了考虑温度影响的井底压力资料校正方法。分析了两种不同温度变化范围对气井试井解释参数及结果影响的变化规律。对比分析表明,当测试井温变化大于10℃时,温度差异对压力的影响校正不可忽略。该研究为现场试井压力资料解释提供了技术支持。Formation temperature is a sensitive factor in gas pressure testing. Correction method is established considering the influence of temperature on the pressure according to the relationship between pressure and temperature. Practical data interpretations show that two different kinds of temperature changing range have different effects on the interpretafion parameters. When the temperature variation is more than 10℃,temperature correction cannot be ignored. This study provides technical support for the gas well testing interpretation.
