Hydrogenated acrylonitrile butadiene rubber (HNBR) has been widely used in many products that serve as sealing components for downhole operations in the energy industry, especially downhole permanent packers. A reliable methodology needs to be developed to predict operational limits for the elastomer during various tool deployments and operations. These operational limits are mostly based on laboratory life prediction tests derived from industry standards meant for material selection or screening. However, the conventional life prediction method cannot capture the effect of size/shape/stress and adequately predict the sealing performance of an actual elastomeric component under downhole operations. To fill this gap, a lifetime prediction methodology for a downhole HNBR packer was developed based on fundamental material behavior such as viscoelasticity, hyperelasticity, chemical/physical degradation from laboratory aging tests, and finite element analysis. Thereafter, the proposed methodology was used to develop an operational limit for the downhole packer in completion brine, calcium bromide. The results showed that the proposed methodology was not limited to the size or shape of the elastomeric product and can be readily extended to develop a successful operational limit for various elastomeric components in the energy industry.

预测能源行业井下应用氢化丁腈橡胶封隔器元件操作极限的新方法

氢化丁腈橡胶（HNBR）在能源行业作为井下作业密封件的许多产品中得到广泛应用，尤其是井下永久封隔器。需要开发一种可靠的方法来预测弹性体在各种工具部署和操作期间的操作限制。这些操作限制主要基于源自用于材料选择或筛选的行业标准的实验室寿命预测测试。然而，传统的寿命预测方法无法捕捉尺寸/形状/应力的影响，也无法充分预测实际弹性体部件在井下作业下的密封性能。为了填补这个空白，井下 HNBR 封隔器的寿命预测方法是基于基本材料行为开发的，例如粘弹性、超弹性、实验室老化测试的化学/物理退化和有限元分析。此后，所提出的方法被用于制定井下封隔器在完井盐水溴化钙中的操作限制。结果表明，所提出的方法不限于弹性体产品的尺寸或形状，并且可以很容易地扩展到为能源工业中的各种弹性体部件制定成功的操作限制。溴化钙。结果表明，所提出的方法不限于弹性体产品的尺寸或形状，并且可以很容易地扩展到为能源工业中的各种弹性体部件制定成功的操作限制。溴化钙。结果表明，所提出的方法不限于弹性体产品的尺寸或形状，并且可以很容易地扩展到为能源工业中的各种弹性体部件制定成功的操作限制。
