深层地下卤水资源量的评价具有较大难度,一方面由于深部地质及水文地质参数难以准确获取,另一方面地下卤水资源量评价方法尚无规范可循。传统的深层卤水区域资源量评价方法一般采用容积法,但容积法对储卤层空间形态描述较简单,同时也无法处理深层卤水各参数严重不均一的问题,容易引起误差的累积。提出了容积法的一种改进模型,首先利用Opengl API三维渲染技术来建立储卤层三维模型,再利用克里格法对储卤层三维模型进行网格化,建立模拟单元,用模拟的方法来解决各参数的不均一性,进而求取资源量。该方法继承了资源量评价中“圈区算量”的基本思想,可以获得更准确的计算结果。为了便于该方法的应用,进行了软件实现,并以四川盆地东北部某储卤构造为例对该构造资源量进行了试算。结果表明该方法能更充分地利用深部地质参数,是对容积法的一种有效改进。
The evaluation of deep underground brine resources is more difficult because of the difficulty of obtaining accurate geological and hydrogeological parameters in depth. On the other hand, there is no standard to evaluate underground brine resources. However, the volumetric method has a simpler description of the space shape of the storage brine and the inability to deal with the severe heterogeneity of the parameters of the deep brine, which easily leads to the accumulation of errors. An improved model of volumetric method is proposed. Firstly, Opengl API three-dimensional rendering is used to build a three-dimensional model of storage halves. Then, the three-dimensional model of storage halves is meshed by using the Kriging method. The simulation unit is established. To solve the heterogeneity of various parameters, and then find the amount of resources. This method inherits the basic idea of “circle area calculation ” in the evaluation of resources, so as to obtain more accurate calculation results. In order to facilitate the application of this method, the software implementation was carried out, and the amount of structural resources was tentatively calculated by taking a brine storage structure in the northeastern Sichuan Basin as an example. The results show that this method can make full use of deep geological parameters and is an effective improvement on volumetric method.
