项目摘要

When cold fluid flows into fractures within a rock, the rock cools down and the cooling causes thermal contraction of the rock around the fractures. As a result, the fractures are likely to open and to be more permeable. We analyze the effect of remote compressive stresses on fracture opening associated with cold fluid flow by using a 2D FEM code. The results show that the fracture opening will be suppressed by remote compressive stresses, but even in such a condition, the considerable increase in fracture opening and permeability will appear when the temperature of injected fluid is smaller than a critical value T_c. This value is given as a function of remote compressive stresses, fracture pressure, and elastic properties of rock. In order to verify the theoretical prediction, we carried out laboratory experiments using a cylindrical specimen. There exists an artificial fracture passing through the specimen in the axial direction, and the experiments were proceeded as follows ; (i)apply a confining stress to the specimen, (ii)elevate the specimen's temperature to a certain level, (iii)inject cold water into the fracture by a constant pressure, and measure the injection rate, (iv) estimate the fracture permeability from the measured injection rate. From the results of experiments, we confirmed that the fracture permeability increases gradually with decreasing the injection temperature, and the increasing rate changes dramatically when the injection temperature becomes lower than the critical value T_c as theoretically predicted.
当冷流体流入岩石内的裂缝时,岩石冷却下来,并且冷却引起裂缝周围的岩石的热收缩。因此,裂缝可能会打开,并且更具渗透性。我们使用二维有限元程序分析了远程压应力对冷流体流动下裂缝张开的影响。结果表明,远场压应力会抑制裂缝的张开,但即使在远场压应力作用下,当注入流体温度低于临界值Tc时,裂缝张开度和渗透率仍会显著增加。该值作为远程压缩应力、破裂压力和岩石弹性性质的函数给出。为了验证理论预测,我们进行了实验室实验,使用圆柱形试样。在试件的轴向存在一条贯穿试件的人工裂缝,实验过程如下:(i)对试件施加围压,(ii)将试件的温度升高到一定水平,(iii)以恒定压力向裂缝中注入冷水,并测量注入速率,(iv)由测量的注入速率估算裂缝渗透率。实验结果表明,随着注入温度的降低,裂缝渗透率逐渐增大,当注入温度低于理论预测的临界值Tc时,裂缝渗透率的增大速率发生急剧变化。
