In recent years, there has been a growing interest in the application of distributed acoustic sensing (DAS) technology in the field of oil and gas geophysics. DAS technology utilizes fiber optic cables as virtual sensors to continuously monitor and detect various physical parameters along the length of the cable. This innovative approach has shown great potential in improving efficiency and accuracy in geophysical surveys.
近年来，对分布式声波传感（DAS）技术在油气地球物理领域的应用产生了越来越大的兴趣。DAS技术利用光纤缆线作为虚拟传感器，可以连续监测和检测沿着光纤长度的各种物理参数。这种创新方法在提高地球物理勘探效率和准确性方面展现出巨大潜力。 One of the main advantages of DAS technology is its ability to provide high-resolution data over long distances, allowing for a more comprehensive understanding of subsurface structures. Traditional seismic acquisition methods often require numerous sensors to be placed at regular intervals, which can be time-consuming and expensive. DAS technology eliminates this need by using an existing fiber optic cable as a continuous sensor, resulting in
significant cost savings and improved operational efficiency.
DAS技术的主要优势之一是它能够在长距离上提供高分辨率的数据，从而更全面地了解地下结构。传统的地震采集方法通常需要将大量传感器安装在规律间隔处，这可能费时费钱。DAS技术通过利用已有的光纤缆线作为连续传感器，消除了这个需求，从而实现大幅降低成本和提高运营效率。
In oil and gas exploration, DAS technology can be used for a variety of applications. It has been successfully applied in seismic imaging, reservoir monitoring, and hydraulic fracture monitoring, among others. DAS technology allows for real-time measurements of pressure, temperature, strain, and vibration along the fiber optic cable. This information can then be used to determine the location and characteristics of subsurface formations and fluid movements.
在油气勘探中，DAS技术可应用于多种领域。它已成功应用于地震成像、储层监测和水力压裂监测等方面。DAS技术能够实时测量光纤缆线上的压力、温度、应变和振动。这些信息可以被用来确定地下构造和流体运动的位置和特征。
Furthermore, DAS technology has the potential to reduce environmental impact compared to traditional methods. The use of fiber optic cables eliminates the need for extensive cabling and reduces the disturbance of natural habitats during survey operations. Additionally, DAS technology allows for continuous monitoring, providing valuable data on any changes or events that occur over time.
与传统方法相比，DAS技术具有减少环境影响的潜力。使用光纤缆线消除了大量布线的需求，并减少了在勘探作业期间对自然栖息地的干扰。DAS技术可以实现连续监测，在时间上提供有价值的数据变化和事件。
In conclusion, the application of DAS technology in oil and gas geophysics has shown promising results. Its ability to provide high-resolution data over long distances, cost savings, and reduced environmental impact make it a valuable tool for exploring subsurface structures and monitoring reservoirs. As technology continues to advance, we can expect further advancements and innovative applications of DAS in the field of oil and gas exploration.
在油气地球物理领域中，DAS技术的应用展示了令人鼓舞的结果。其能够在长距离上提供高分辨率数据、节约成本和减少环境影响使其成为探索地下结构和监测储层的宝贵工具。随着技术的不断进步，我们可以预期DAS在油气勘探领域中将有进一步发展和创新应用。
