| 文章从简化的干热岩裂隙储层模型出发,给出了一维初边值微分方程及其解析解,计算裂隙水温度与位置及时间的关系,得出了干热岩开发过程中生产井的出水温度的影响因素及其影响方式。实验结果表明,生产井与注水井之间距离要足够大,才能开采出温度较高的热水,并能有足够的开采年限。在理论上对干热岩开发二维、三维模拟计算及实际开发有一定的作用。 |
| 英文摘要: |
| In this paper, we use a simplified fissure reservoir model of the hot dry rock and derive the 1D differential equation of initial boundary value and its analytic solution. The temperature and position of the fissure water and the relationship with the time are calculated. From the result we can obtain the influencing factors of the fissure water temperature of the injection well during the development of the hot dry rock. The experimental test result demonstrated that the distance between production well and injection well should be far enough, then the fissure water with higher temperature can be extracted, and will have long production life years. In theory, it has certain instructive effects on 2D and 3D simulation calculation of the hot dry rock and real hot dry rock development. |
