SQUID在石油勘探中应用的可行性分析

Feasibility analysis of SQUID in petroleum exploration

近年来,利用磁测找油已经成为了非地震油气物探的一种重要方法。由于地下油气藏的存在会引起微磁异常,这些磁异常在经过数据处理之后,可以提供与油气藏之间高度的相关性依据。超导量子干涉仪(Superconducting quantum devices,常缩写为SQUID)作为灵敏度高、噪声低的磁测仪器,给精密磁测提供了很好的物质基础。文中在分析了SQUID的结构功能和磁测在找油方面的作用后,对SQUID在石油勘探中应用的前景进行了分析与展望。

In recent years, the use of magnetic measurement for oil has become an important method of non - seismic geophysical exploration of oil and gas. Due to the existence of underground reservoirs, they can cause micro magnetic anomaly. The magnetic anomaly, after being processed, can provide a high degree of correlation between micro magnetic anomaly and reservoir. Superconducting quantum interferometer, with its high sensitivity and low noise property, provides a good material basis for precise detection. Based on the analysis of the structure and function of SQUID and magnetic survey, this essay analyzed the role of SQUID in oil exploration and presented the prospect of the SQUID application in oil exploration.
