CONVENTIONAL DHEs
Although it has been known for many years that the use of
a perforated casing somewhat smaller than the wellbore
increased the output of a DHE,there has been no
information reported regarding the relative improvement.In
order to quantify the improvement,obtain information about
the convection cell with regard to energy balances within the
well,and provide data for model evaluation,tests were run
on DHEs installed in a well before and after casing.
Figure 3 shows the energy extraction rates achieved from
both the cased and uncased well tests for a 64 m loop of 5-
cm black iron pipe and a 65.5 m deep well.As expected,the
DHE in the cased well was able to produce a significantly
higher output than in the uncased well.At the highest
output,DHE energy extraction from the cased well was 175
percent that of the uncased well,about 500 kW.However,
it must be remembered that energy production would not be
that high in the normal mode of operation since the inlet
temperature for the test was lower than it would usually be
and the ∆T across the DHE was 63oC,much more than in
actual operation.
Observation of the well fluid temperature at several depths
inside the cased well revealed that with sufficient cooling,
the convection cell reversed direction (see Figure 2,curves
2 and 3),going down the inside of the casing and up the
outside–just the opposite of when there is no DHE present in
the cased well (curve 1 of Figure 2)

常规DHEs能源提取率
虽然它已经被很多年前就知道使用,一种有孔有点小于井筒套管,增加后方的输出,还没有
关于信息报道其相应的改进.在以量化的改进、获取信息对流细胞内能源平衡.
嗯,并提供数据模型评估、测试运行,在DHEs安装在一个好之前和之后的套管.图3显示了萃取率的能量,套管和uncased都好测试循环的5 - 64米,黑铁管厘米和65.5米深的井.正如所料,
它在涂好能够制造显著,比uncased增加产量.在最高输出,她从能量提取封装好,是在175年
uncased百分比,嗯,差不多500千瓦.然而,必须记住,能源生产不会高在正常的运作模式,由于进口.为测试温度低于它通常会和∆T在比赛进行到63摄氏度,远不止实际操作.
观察井流体温度在几个深处,在封装好显示与充分冷却,对流细胞反方向(见图2、曲线2和3),去了,里面的套管的相反的如果没有比赛进行到现在封装的(曲线1图2).
