技术采用显微镜细节创造连续应变型材，从而提高了地下油和天然气系统的安全性和生产效率

ROANOKE, Va.--(BUSINESS WIRE)--Oct. 15, 2020-- Luna Innovations Inc..（纳斯达克：LUNA）今天宣布，与Shell的GameChanger™早期技术计划合作，它开发了一种创新概念，用于使用其光纤传感解决方案测量地下岩石的原位应力。部署时，该技术将以无与伦比的一致性和深度分辨率提供关键测量，允许更安全，更高效的操作。

Businesses that rely on underground operations, such as the petroleum and geothermal industries, require accurate estimates of in-situ stress, which refers to the existing pressure that exists underground before a hole is drilled. This affects drilling, surveying, and fluid injection (hydraulic fracturing, water flooding, CO2 sequestration) as well as phenomena such as fault re-activation and induced seismicity.

The new technology, Luna’s Continuous Horizontal In-situ Stress Logger (CHISL), uses Luna’s high-definition fiber optic sensing (HD-FOS) and ODiSI® product to obtain direct, high-resolution strain measurements of induced micro-fractures and borehole deformation. New algorithms then process the strain measurements at the borehole to estimate in-situ maximum and minimum horizontal stress and their orientations.

“这种新技术的发展 - 使用现有的Luna光纤传感器和我们的ODISI仪器 - 让石油和天然气行业评估患有不可测量的关键参数，” 斯科特格雷夫, President and Chief Executive Officer of Luna. “We greatly appreciate Shell GameChanger for its support as well as its expertise with use cases in the oil & gas industry. Together, we show how the industry’s toughest test, measurement, and analysis challenges can be tackled with ideas like CHISL.”

Luna的ChiSl传感器将光纤传感器集成到柔性液压套筒中，该液压套筒将压力施加到钻孔壁，直到形成小的纵向骨折。与液压压裂不同，其中流体流入裂缝并导致它们远离钻孔的长度，ChISL不允许流体流入诱导的骨折。

“对原位应力的可靠估计对于石油和天然气行业的许多应用至关重要。例如，液压压裂在Shales中的成功大大取决于所产生的骨折高度，这又通过深度的应力变化强烈控制。Luna的技术将允许使用前所未有的解决方案来估算压力深度型材，“评论说 Alexei Savitski，壳牌的地质力学主题专家。“最大水平应力是最不确定的地下特性之一，通常从其他数据推断出来。但是，CHISL将使这种不确定性显着减少，这对于评估故障重新激活和诱导地震性的风险至关重要。“

CHISL传感器将提供新型数据，可以利用以提高未来地下工程系统的安全性，生产效率和优化。使用粗糙化传感器的未来现场操作可以为前所未有的钻孔长度和比传统的液压压裂技术更少的时间产生原位应力测量。除了岩层的应力分析外，还为液压压裂规划，其他应用包括石油井的完整性感测，以及复杂油井的优化钻孔。
