She descended deeper into this stuffy well . 她深入这个拥挤不堪的井孔。
2.
Above the inversion point the temperature in the bore hole decreases as the depth decreases . 在反向点以上，井孔内的温度将随着深度的变浅而下降。
3.
If a hole is drilled, the pressure can be reduced in the hole and thereby in the rock section adjacent to the hole . 如果一个井孔钻成，井内压力就要下降，井孔附近岩体内的压力也跟着下降。
4.
aggressive corrosion of well casing and heat exchangers can be caused by , hcl, , and other acids. 井孔套管和热交换器的侵蚀性腐蚀是H2S，HCL，H2SO4和其他酸类引起的。
5.
The heat contained in a natural steam field is exploited by drilling a suitable number of wells down to the reservoir . 天然蒸气田所含有的热能可以通过钻井的方法，即打适当数量的井孔到达热储的方法进行开采。

The results show that the wellhole and pumping condition , such as depth of the pump , quantity of pumping , all have great influence on the observational result 结果表明，井孔条件，抽水条件，如水泵深度、抽水量等因素的改变对观测结果产生较大影响。
9.
Based on the previous work , the equations of motion and elastodynamics are changed . a high - order staggered velocity - stress finite - difference formula of the acoustic field in borehole are set up in cylindrical coordinate , and the corresponding code is accomplished 本文在弹性波动力学的基础上，将运动方程和本构方程作适当变形，采用交错网格技术建立了井孔波动方程在柱坐标系下的速度?应力高阶有限筹分公式，并编制了相关计算程序。
