前言

  Managed aquifer recharge (MAR) is the intentional recharge of water to aquifers forsubsequent recovery or environmental benefit. Aquifers may be recharged by a range ofmethods using wells and infiltration systems, to increase groundwater supplies and improvetheir quality or to redress saline ingress or land subsidence.  To date in China the major applications of MAR have been in infiltration basinsestablished in the 1990s, such as the groundwater dams, infiltration wells and trenches inShandong province, with a total recharge capacity exceeding 200 million m3/a. River bankfiltration projects have been established in South China to improve the quality of water forindustry and agriculture. Injection wells are now in routine operational use for sustainablemanagement of geothermal reservoirs in North East China with reinjection of 4 million m3/a.In addition, there are recharge projects to reduce land subsidence in Shanghai. Ademonstration project in Beijing is exploring wastewater treatment processes to precederecharge for sustainable projects that protect human health. New research in Jinan is startingto explore recharge of roof rainwater to replenish a karst aquifer that feeds historicallyimportant springs.  In Australia infiltration basins have been used, for 50 million m3/a of agriculturalsupplies, since the late 1970s, commencing in the Burdekin Delta, Queensland. More recentlyurban stormwater and reclaimed water resources have been used in MAR, via injection wellsin South Australia and infiltration projects utilising soil aquifer treatment in WesternAustralia and Northern Territory.  The China-Australia Managed Aquifer Recharge (MAR) Training Workshop held inJinan October 27 ~ 31, 2008, was supported by the AusAID Public Sector Linkages Program,the National Natural Science Foundation of China, Shandong Institute of Geological Surveyand Jinan Water Resources Bureau in order to facilitate the exchange of information andexperience on MAR among Australian researchers and Chinese researchers and water resource managers. In large parts of both countries groundwater is a resource under stress, and in urban areas the possibilities of urban runoff and treated sewage for augmenting groundwater supplies are being trialled or used. This workshop proceedings documents the way MAR is being used or could be developed to address some of Chinas water resource management challenges. It provides a guide to developing MAR schemes based on Australian and Chinese experience. The material presented takes account of technical, health or environmental risks and the methods used to manage those risks.

章节摘录

  The
cooling
of
produced
geothermal
fluid
caused
by
injection
of
colder
fluid
has
beenreported
in
a
few
high-enthalpy
geothermal
fields.
For
low-enthalpy
geothermal
fields,
therehas
not
been
any
such
report,
even
in
the
cases
where
the
distance
between
the
productionwell
and
injection
well
is
rather
small.Therefore,
it
may
be
concluded
that
forproduction-reinjection
doublets
in
low-enthalpy
geothermal
fields,
one
does
not
have
to
fearabout
the
cooling
of
the
production
water,
if
the
distance
between
production
well
andinjection
well
is
greater
than
a
few
hundred
meters,
and
the
amount
of
reinjection
in
not
veryhuge.
In
designing
the
distance
of
reinjection
and
production
wells
of
a
doublet
system,
a
fewfactors
should
be
considered,
including
the
type
of
geothermal
reservoir,
the
geologicalstructure
of
the
geothermal
field,
the
permeability
and
thickness
of
the
reservoir,
the
directionof
fluid
flow,
the
temperature
difference
between
the
reservoir
and
reinjection
water,
the
flowrate
of
reinjection
etc.
But
in
the
cases
that
a
large
number
of
reinjection
wells
and
productionwells
will
be
placed
among
a
rather
small
area,
care
has
to
be
taken,
and
proper
tests
have
tobe
carried
out
and
proper
modeling
has
to
be
done
before
any
such
injection
project
is
started,so
as
to
avoid
premature
thermal
breakthrough.  5.2
Tracer
test  Tracer
breakthrough
can
be
a
very
good
precaution
for
thermal
breakthrough.
Tracertesting
is
one
of
the
most
important
aspects
of
geothermal
reinjection,
which
has
become
aroutine
for
reinjection
experiments.
Tracer
tests
can
provide
information
about
the
flow
pathsand
the
flow
velocity
of
the
geothermal
fluids
between
the
injection
and
production
wells.
Forfractured
reservoirs,
the
volume
of
the
aperture
can
be
deduced
from
the
tests.
Thisinformation
can
be
used
to
predict
the
cooling
due
to
reinjection
(Axelsson
and
Stefnsson,1999).
For
reinjection
projects
that
are
large-scale
or
a
number
of
production
and
reinjectionwells
in
a
relatively
small
area,
it
is
strongly
proposed
that
a
tracer
test
be
carried
out.  5.3
Monitoring  Monitoring
is
one
of
the
most
important
elements
for
geothermal
management.
For
ageothermal
field
with
reinjection,
a
proper
monitoring
program
is
even
more
important.Besides
the
monitoring
of
reservoir
pressure,
temperature,
amount
of
production,
chemicalcomposition
of
geothermal
fluid
etc,
the
water
level
in
the
injection
wells,
temperature
ofinjection
water,
amount
of
injection
and
chemical
composition
of
injection
water
should
alsobe
monitored.
The
purpose
is
to
find
out
the
changes
of
the
geothermal
system
caused
byreinjection,
especially
the
cooling
of
the
produced
geothermal
water.
