| 英文摘要 | Accurate and rapid tight reservoir permeability measurements are important for unconventional gas production. However, traditional transient pressure pulse attenuation techniques take a long time to measure reservoir cores with nano-Darcy scale permeability. In this study, a novel radial-flow transient technique is proposed to achieve fast and accurate measurements of tight-structure rocks. Two gas containers of the same volume and two pressure pulses of the same size and opposite direction are designed for permeability measurement. Based on this, a mathematical model is established to verify the feasibility of the novel transient technology. Through the analysis of the model, the fluid attenuation law of space and time is compared with that using the traditional technique. The results show that the attenuation of radial fluid pulse is significantly faster; and compared with axial flow attenuation, the measurement time can be reduced more than 10 times. One more advantage of this method is that it can effectively eliminate gas compressed storage and adsorption-induced permeability measurement error. The proposed technique was experimentally verified and proved to be a fast approach for laboratory permeability measurements; meanwhile, the technique is capable of accurately characterizing the gas flow behavior and then reliably used for determining the permeability of gas sink in the range of nano-Darcy scale. |
