实施例二
本发明实施例提供了一种构建双溶腔盐穴储库地面沉降预测模型的方法，为了便于理解，现结合上述实施例一的内容，对本发明实施例提供的构建双溶腔盐穴储库地面沉降预测模型的方法进行详细地解释说明。参见图2，本实施例提供的方法流程包括：
201：获取双溶腔盐穴储库的信息，根据双溶腔盐穴储库的信息建立双溶腔盐穴储库的三维地质分析模型。
其中，双溶腔盐穴储库的信息包括但不限于双溶腔盐穴储库的地质信息及腔体形状参数等。双溶腔盐穴储库的地质信息包括但不限于溶腔盐穴储库的纵横剖面图、地层分布、岩性以及岩土体的物理力学指标等。腔体形状参数包括但不限于腔体的体积、高度、宽度、腔距等。其中，地层为土层、泥层、盐层、夹层等，本实施例不对地层作具体的限定。岩土体的物理力学指标包括但不限 于弹性模量、泊松比、粘聚度、抗拉强度等。
关于获取双溶腔盐穴储库的地质信息的方法，包括但不限于采用地质分析设备获取。关于获取双溶腔盐穴储库的腔体形状信息的方式，包括但不限于采用测量设备获取。
在对双溶腔盐穴储库的岩土体的物理力学指标进行研究可知，双溶腔盐穴储库的腔体形状及地层分布对双溶腔盐穴储库的岩土体的物理力学指标有重要影响：不同腔体形状的双溶腔盐穴储库的岩土体的物理力学指标是不同的，同一双溶腔盐穴储库的不同地层的岩土体的物理力学指标也是不同的。
为了直观地展现双溶腔盐穴储库的不同的地层所具有的不同力学性能，下面以双溶腔盐穴储库的每个单腔体积为25万立方米、每个腔体高140米、每个腔体宽度为60米的为例进行介绍。具体参见表1。
表1
Figure PCTCN2015096203-appb-000001
其中，表中Pa为帕斯卡，°为度，Kg/m3为千克每立方米。从表1可以看出，不同地层的岩土体的物理力学指标是不同的，同一地层不同的深度的岩土体的物理力学指标也是不同的。
进一步地，为了构建双溶腔盐穴储库地面沉降预测模型，在获取了双溶腔盐穴储库的信息之后，需要根据双溶腔盐穴储库的信息建立双溶腔盐穴储库的三维地质分析模型。关于根据双溶腔盐穴储库的信息建立双溶腔盐穴储库的三维地质分析模型的方法，包括但不限于根据获取到的双溶腔盐穴储库的信息采用建模软件构建双溶腔盐穴储库的三维地质分析模型。本实施例不对采用的建模软件进行限定，具体实施时，可根据双溶腔盐穴储库的信息建立双溶腔盐穴储库的三维地质分析模型即可。
202：选取双溶腔盐穴储库的三维地质分析模型的关键点。
由于双溶腔盐穴储库的三维地质分析模型的关键点能够代表整个双溶腔盐穴储库的情况，因此，在建立了双溶腔盐穴储库的三维地质分析模型之后，可在双溶腔盐穴储库的三维地质分析模型上选取关键点，以使后续步骤可通过对选取的双溶腔盐穴储库的三维地质分析模型关键点进行分析，构建双溶腔盐穴储库地面沉降预测模型。
具体地，选取双溶腔盐穴储库的三维地质分析模型的关键点的方式，包括但不限于采用如下方式：
第一步，将双溶腔盐穴储库的两个拱顶分别向地面投影，并将投影连线的中点确定为中心点；
第二步，以中心点为起点，以预设距离为间隔，选取至少两个点，并将中心点和选取的至少两个点作为双溶腔盐穴储库的三维地质分析模型的关键点。
其中，预设距离可以是20米、50米、60米等，本实施例不对预设距离作具体的限定。
对于上述过程，为了便于理解，下面将以一个具体的例子进行详细地解释说明。
图3为双溶腔盐穴储库的关键点设置的示意图。在选取双溶腔盐穴储库的三维地质分析模型的关键点时，首先，将图3中的双溶腔盐穴储库的两个拱顶分别向地面作投影，并将投影进行连线得到连线的中心点为A点；其次，设定预设距离为25米，以中心点A点为起点、25米为间隔选取关键点，得到的关键点有A、B、C、D、E等。
需要说明的是，上述在选取关键点时以相同的预设距离为步长选取的关键点，在实际选取关键点时，由于双溶腔盐穴储库的长度较大，靠近中心点的位置的关键点为对双溶腔盐穴储库地面沉降进行预测的主要分析点，因此，在选取关键点时，可在靠近中心点处密集取点，在离中心点较远的地方上以更大的步长选取关键点。
203：对关键点进行流变分析，得到关键点的流变分析结果。
为了构建更为精准的双溶腔盐穴储库地面沉降预测模型，以便于对双溶腔盐穴储库的地面沉降进行预测，本实施例提供的方法需要对关键点进行流变分析，进而得到关键点的流变分析结果。
具体地，对关键点进行的流变分析，包括但不限于采用如下步骤：
第一步，根据盐岩的流变实验结果确定双溶腔盐穴储库的三维地质分析模型的流变模型；
关于根据盐岩的流变实验结果确定双溶腔盐穴储库的三维地质分析模型的 流变模型的方法，包括但不限于：对双溶腔盐穴储库的三维地质分析模型进行预设次数的盐岩流变实验，并获取预设次数的盐岩流变实验的实验结果，将获取到的盐岩流变实验的结果进行拟合，从而得到双溶腔盐穴储库的三维地质分析模型的流变模型。其中，将获取到的盐岩流变实验的结果进行拟合时，包括但不限于采用如下公式进行拟合：
ε＝εl+εt+εs＝C+B(1-exp-βt)+A(σ1-σ3)nt
其中，
Figure PCTCN2015096203-appb-000002
为盐岩瞬时变形，
Figure PCTCN2015096203-appb-000003
为稳态蠕变率，εt为初始蠕变应变，C为常数，A、n为材料参数，σ1和σ3分别为最大应力和最小主应力，B、β为材料参数，t为时间。
在采用上述公式进行拟合之后，为了便于根据确定双溶腔盐穴储库的三维地质分析模型的流变模型进行后续的分析计算，需要先确定双溶腔盐穴储库的三维地质分析模型的流变模型的模型参数。关于确定双溶腔盐穴储库的三维地质分析模型的流变模型的模型参数的方法，本实施例不作具体的限定。
以表1所示的双溶腔盐穴储库的信息构建的三维地质分析模型为例，确定的该双溶腔盐穴储库的三维地质分析模型的流变模型的模型参数，可参见表2。
表2
Figure PCTCN2015096203-appb-000004
Figure PCTCN2015096203-appb-000005
其中，MPa为兆帕斯卡。
第二步，根据流变模型采用数值模拟分析方法对关键点进行流变分析。
其中，数值模拟分析方法也叫计算机模拟方法，数值模拟分析方法是以电子计算机为手段,通过数值计算和图像显示的方法,达到对工程问题和物理问题乃至自然界各类问题研究的目的的一种方法。为了确定内压和流变时间对双溶腔盐穴储库地面沉降的影响，进而根据确定的双溶腔盐穴地面沉降情况与内压及流变时间的关系，构造更为精准的双溶腔盐穴储库地面沉降预测模型，本步骤可根据流变模型采用数值模拟分析方法对关键点进行流变分析。
其中，在根据流变模型采用数值模拟分析方法对关键点进行流变分析时，可分为如下两种情况：
第一种情况：流变时间相同，内压不同；
为了确定内压对双溶腔盐穴地面沉降的影响，可采用单一变量原则，在同一流变时间下，对双溶腔盐穴储库在不同内压下进行流变分析。
为了便于理解上述过程，下面将以内压为5MPa和10MPa为例进行详细地解释说明。
图4为在流变时间相同时关键点的沉降量随内压变化的示意图。从图4可知，当流变时间为2年时，关键点在内压为5MPa时的地面沉降量要大于内压为10MPa时的地面沉降量；当流变时间为5年时，关键点在内压为5MPa时的地面沉降量要大于内压为10MPa时的地面沉降量；当流变时间为10年时，关键点在内压为5MPa时的地面沉降量要大于内压为10MPa时的地面沉降量；当流变 时间为20年时，关键点在内压为5MPa时的地面沉降量同样要大于内压为10MPa时的地面沉降量。因此，通过对图4的分析可得出如下结论：流变时间相同时，内压越多，双溶腔盐穴储库的地面沉降量越小。
第二种情况：流变时间不同，内压相同。
为了确定流变时间对双溶腔盐穴地面沉降的影响，可采用单一变量原则，在内压相同下，对双溶腔盐穴储库在不同流变时间下进行流变分析。
对于上述过程，为了便于理解，下面将以一个具体的例子进行详细地解释说明。
图5为在内压相同时关键点的沉降量随流变时间的变化的示意图，以设定的关键点为图3中的A、B、C、D、E，内压为10MPa为例。从图5可以看出，在流变时间为10年时，关键点A的地面沉降量小于关键点B的地面沉降量，关键点B的地面沉降量小于关键点C的地面沉降量，关键点C的地面沉降量小于关键点D的地面沉降量，关键点D的地面沉降量小于关键点E的地面沉降量，而关键点A、B、C、D、E距离中心点的距离是逐渐增大的，因此，通过对图5的分析可得出如下结论：流变时间相同时，随着关键点距离双溶腔盐穴储库的中心距离越远，地面沉降量越大。在流变时间不同时，以关键点为A点为例，在流变时间为5年时关键点A的地面沉降量要小于流变时间为10年时的地面沉降量，在流变时间为10年时关键点A的地面沉降量要小于流变时间为15年时的地面沉降量，在流变时间为15年时关键点A的地面沉降量要小于流变时间为20年时的地面沉降量，因此，通过对图5的分析还可得出如下结论：流变时间不同时，同一关键点随着流变时间的增大地面沉降量逐渐增大。
综上，通过对关键点进行不同内压下的流变分析，得到关键点的流变分析 结果如下：
第一：流变时间相同时，内压越多，双溶腔盐穴储库的地面沉降量越小。
第二：流变时间相同时，随着关键点距离双溶腔盐穴储库的中心距离越远，地面沉降量越大。
第三：流变时间不同时，同一关键点随着流变时间的增大地面沉降量逐渐增大。
204：根据关键点的流变分析结果构建双溶腔盐穴储库地面沉降预测模型。
由于上述步骤203中已对关键点流变分析，并得到的了关键点的流变分析结果，因此，本步骤在上述步骤203的基础上将根据关键点的流变分析结果构建双溶腔盐穴储库地面沉降预测模型。具体地，根据关键点的流变分析结果构建双溶腔盐穴储库地面沉降预测模型时，可根据关键点的流变分析结果确定各个关键点沉降随时间变化模型及地面沉降水平方向衰减模型，进而将确定的各个关键点沉降随时间变化模型及地面沉降水平方向衰减模型确定为双溶腔盐穴储库地面沉降预测模型。
具体地，由于上述步骤203中在对关键点进行不同内压下的流变分析时，已经得到同一关键点随着流变时间的增大，地面沉降量逐渐增大这一关键点的流变分析结果，因此，本步骤可根据这一流变分析结果确定如下各个关键点沉降随时间变化模型：
S＝a[1-exp(-bt)]
其中S为地面关键点地面沉降量，t为流变时间，a、b为模型参数。
具体地，由于上述步骤203中在对关键点进行不同内压下的流变分析时，已经得到流变时间相同时，内压越大双溶腔盐穴储库的地面沉降量越小，随着 关键点距离双溶腔盐穴储库的中心距离越远，地面沉降量越大的分析结果，因此，本步骤可根据这一流变分析结果确定如下及地面沉降水平方向衰减模型：
Sr＝c-dexp(-erf)
其中，Sr为地面距中心点r处的沉降量，r为距中心点的距离，c、d、e、f为模型参数。
进一步地，构建双溶腔盐穴储库地面沉降预测模型之后，为了更好地对双溶腔盐穴储库地面沉降进行预测，还需对双溶腔盐穴储库地面沉降预测模型进行回归分析，得到双溶腔盐穴储库地面沉降预测模型的模型参数，进而根据双溶腔盐穴储库地面沉降预测模型及模型参数对双溶腔盐穴储库地面沉降进行预测。
其中，回归分析是在掌握大量观察数据的基础上利用数理统计的方法建立因变量与自变量之间的回归关系函数表达式的方法。具体地，在对双溶腔盐穴储库地面沉降预测模型进行回归分析，得到双溶腔盐穴储库地面沉降预测模型的模型参数可参见表3和表4。
