摘要:

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。

Abstract:

Deep brine resource evaluation is a very difficult issue. On the one hand, deep brine’s geological and hydrogeological parameters are difficult to obtain, and on the other hand deep brine’s evaluation method is lack of standard. Traditional evaluation method of deep brine resources is volumetric method. But volumetric method is too simple to describe spatial form of brine reservoir, and it also can not  solve the problem of deep brine parameters serious heterogeneity. Volumetric method is easy to cumulative error. This paper proposes an improved model of the volumetric method. At first, it uses Opengl API 3D rendering technology to create threedimensional model of brine reservoir. Then, it uses Kriging method to set grid on the brine reservoir 3D model and builds  simulation unit on the brine reservoir 3D model. At last, it uses simulation methods to solve the problem of parameters serious heterogeneity and calculates the resources. This method inherits the traditional calculating ideas, and it can obtain more accurate calculation result. In order to apply this method, a software is develops. This paper evaluates one brine structure’s resources of Northeastern Sichuan Basin as an example. This method can more fully exploit the deep geological parameters, and its result is better than volumetric method. This method is an effective improvement of the volumetric method.

Key words: Deep brine    3D model    Kriging method    Resource evaluation
