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。
In the past, most injection well testing methods were based on isothermal models. The single-phase well test model of non-isothermal injection wells proposed by Bensen and Bodvarsson and Woodward and Thambynayagam, as well as the integral solution of temperature and pressure, are presented. The results show that when the Peclet number is quite small And the pressure approximate solution, and compared with Theis solution under isothermal condition, the results show that the effect of temperature change during injection is similar to the effect of subsequent permeability change. The model can be used to explain the unstable temperature and pressure test of intermittent injection wells.
