Abstract

The results of studies are presented for the influence of hydrodynamic factors on the occurrence of nitric thermal waters in crystalline massifs based on the example of the Kuldur field. The results of two-dimensional modeling based on the FEFLOW software are considered for several versions of the formation and circulation of thermal waters in the treated area. The modeling parameters included temperature within 130–140°C calculated on the basis of geothermometers, as well as the residence time of the waters in the rock massif (68 000–254 000 years) evaluated by ¹⁴C- and ⁴He-dating. The modeling results show that the filtration parameters of the granite massif are the main factors that control the fluid motion dynamics and, hence, the relative age of thermal waters. It was also found that the filtration characteristics of the fault zone considerably affect the discharge temperature of thermal waters.

以 Kuldur 场为例的岩石结晶体中硝酸热水形成的概念模型

摘要

以Kuldur油田为例，介绍了水动力因素对结晶地块中硝酸热水形成的影响的研究结果。基于 FEFLOW 软件的二维建模结果被考虑用于处理区域中热水的形成和循环的几个版本。建模参数包括根据地温计计算的 130-140°C 范围内的温度，以及通过¹⁴ C-和^{4评估的水在岩体中的停留时间（68 000-254 000 年）}他约会。模拟结果表明，花岗岩地块的过滤参数是控制流体运动动力学的主要因素，因此也是控制热水相对年龄的主要因素。还发现断裂带的过滤特性对热水的排放温度有很大影响。
