传统的水文地质参数计算,是建立在地下水的密度是常数的基础之上。对于地热水而言,无论是在天然状态下,还是在抽水过程中,由于井筒内各段水温不同导致水的密度存在差异,表现在试验过程中井内水位高度值的变化。在不相同密度的地下水条件下,需根据井内水位实测资料,计算出孔底压力,进而换算出同密度条件下井内等效降深,为参数计算奠定基础。本文结合生产实例,阐述了井内等效降深的换算方法。
The traditional calculation of hydrogeological parameters is based on the constant density of groundwater. For geothermal water, whether in natural state or during pumping, the density of water varies due to the different water temperatures in the wellbore, which shows the change in the height of the water level in the well during the test. Under the conditions of groundwater with different density, it is necessary to calculate the pressure at the bottom of the hole according to the measured data of the water level in the well, and then calculate the equivalent depth of well in the same density to lay the foundation for parameter calculation. In this paper, production examples, elaborated the equivalent reduction method of well.
