為了評估CO2地質封存場址的安全性及穩定性，必須先了解場址儲氣層之現地應力為重要的課題。本研究考慮不同條件下以音射法(AE)與變形率變化法(DRA)推估岩石預應力，唯不同的岩石有不同的AE及DRA適用性，實際應用在現地之前必須加以探討其可行性。研究場址為台灣中部鐵砧山，根據中油公司的調查，該場址具有CO2地質封存潛能，故本研究以該場址之儲氣層魚藤坪砂岩露頭做為試驗材料，試體可分為直徑5公分及直徑2.28公分尺寸，利用室內反覆應力加載於試體上，使應力記憶於試體之中，再以音射法(AE)與變形率變化法(DRA)推估其室內預應力大小，探討將來運用AE與DRA法結合三維應力場，推估魚藤坪砂岩現地應力的可能性。強度方面則進行高溫高壓三軸試驗，在不同溫度條件下求出符合地溫梯度的破壞準則。

The geological storage of CO2 is a technique to reduce greenhouse gas emissions. To estimate the storage pressure of a CO2 geological storage site, we must evaluate the in-situ stresses of reservoir rock. Acoustic Emission (AE) and Deformation Rate Analysis (DRA) are new core-based techniques to measure the pre-stress of the rock. However, the applicability of AE and DRA on the pre-stress evaluations is different from rock to rock and must be checked. In addition, the CPC indicates that Yutengping sandstone at Tieh-chan-shan is a potential site for CO2 geological storage in central Taiwan. Thus, cyclic loads are applied on the sandstone specimens to memory the pre-stress to the specimens. Then, AE and DRA are applied to the pre-stressed samples to estimate the pre-stress. In the practical applications, delay time can be defined as the time, from which the specimens taken in-situ site to the laboratory. Therefore, the impact of different delay time on the accuracy of pre-stress evaluations must be discussed. The study found that Yutengping sandstone is classified as a weak rock. The Kaiser Effect of AE method on the Yutengping Sandstone is insignificant. But, DRA estimates the pre-stress of the sandstone with the error less than 20%. Additionally, the estimated pre-stress of Yutengping sandstone decreases as the delay time increases.
