摘
要:指出流体在超低渗透油藏中渗流偏离达西定律,符合非线性渗流规律,结合矿场实际和室内
岩芯数据建立了大
45
区块地质模型,采用非线性渗流数值模拟软件进行数值模拟.结果显示,该软件对实
际区块同样具有很好的稳定性,区块开发过程中压力梯皮大部分位于非线性弯曲段,非线性渗流区域占主
导地位,进一步验证了采用非线性数值模拟软件的可行性.相比传统评价方法,该研究增加了压力梯度场
参数,对坪估超低渗储层的有效动用有意义.

Abstract:
Fluid
seepage
in
the
super-low
permeahility
reservoirs
deviates
from
the
Darcy'
s
law
,
instead
confor-
ming
to
the
law
of
nonlinear
seepage.
In
this
paper
,
on
the
hasis
of
practical
field
and
lahoratory
experiment
data
,
the
geological
model
of
Da
45
hlock
is
estahlished
and
the
numerical
simulation
is
carried
on
in
line
with
the
mode
l.
As
to
the
practical
model
,
the
nonlinear
seepage
numerical
simulation
software
also
has
good
stahility
during
the
calculation.
The
calculation
results
show
that
,
most
pressure
gradient
helongs
to
nonlinear
types
and
the
nonlinear
seepage
dominates
in
a
large
scale
of
formation
,
which
further
testifies
to
the
accuracy
and
impor-
tance
of
the
nonlinear
seepage
numerical
simulation
software.
Compared
to
the
conventional
evaluation
method
, a
new
parameter
of
pressure
gradient
is
included
,
which
is
of
significance
to
the
cognition
and
evaluation
of
effective
driving
degree
for
super-low
permeahility
reservoirs.
