摘　　要：以往大部分注水井测试方法是基于等温模型 ,现论述了Bensen和Bodvarsson及Woodward和Thambynayagam提出的非等温注水井单相试井模型及温度和压力的积分解 ,给出在Peclet数相当小时的温度和压力近似解 ,并与等温情况下的Theis解进行比较 ,结果表明 ,注入期间温度变化效应相似于随后的渗透性变化的效应。该模型可用于间断注水井的不稳定温度和压力测试解释。Most of method of injection wells testing are based on equitemperature model formerly.This paper discussed a non equitemperature injection well model in single phase testing well and integral equation of temperature and pressure which presented by Bensen and Bodvarsson,Wood ward and Thambynayagam,gives out temperature and pressure's approximate equation when Peclet value is rather small,meanwhile,compares it to Theis equation in the condition of equitemperature.The result indicates that the temperature changed effect during injection period is approximately equal to the following permeability changed effect.This model is adapted to the well test interpretation of unstable temperature and pressure in discontinuous wells.
