Acid treatment is an important measure to improve production and injection for producer and injector, and pressure transient well test is one of methods for evaluating effects of acid treatment.

酸化是油、气、水井增产增注的重要措施，压力不稳定试井是评价酸化效果的主要手段。

At the same time, corresponding pressure transient curves are drawn. The curve characteristics and influences are analyzed.

同时绘制了相应的压力动态曲线，并对曲线的特征和影响因素进行了分析。

The assumption of constant rock properties in pressure transient analysis gives good results in many oil and gas reservoirs.

在试井分析中通常都是假设岩石特性为常数，这个假设条件在许多油气藏的试井分析中取得了很好的解释结果。

Researchers using the car-sized mobile laboratory have identified transient whirlwinds, mapped winds in relation to slopes, tracked daily and seasonal changes in air pressure, and linked rhythmic changes in radiation to daily atmospheric changes.
