激光雷达在油气直接勘查中的应用前景

在油气藏上方的近地表处,存在许多可用现有遥感手段捕捉到的烃类物质微渗漏异常信息,而且也存在着因油气压造成的烃类气体扩散异常现象。利用遥感直接探测油气藏上方的烃类气体异常,是一种直接而快捷的油气勘查方法,所采用的遥感技术,是目前己用于大气监测、气体化学分析等方面的激光雷达技术。由于激光雷达是激光技术与雷达技术相结合的产物,有着许多独特的特性,并随着这项技术的理论研究逐步深入和应用技术逐渐成熟和提高,将其用于油气直接勘查已成为可能。可以预言,激光遥感的时代不久将到来。文中对激光雷达系统及其定性、定量探测原理以及应用的可行性做了简述。笔者认为,激光雷达是一种远距离探测效果极强的手段,有着广泛的应用前景,并将成为油气资源遥感勘查方面的一个重要的发展方向。

LADAR APPLICABLE PROSPECT IN THE DIRECT EXPLORATION OF OIL AND GAS RESOURCES

Above oil-gas reservoir-on the earth's surface, there is abnormal concentration of hydrocarbon gas because of the pressure of oil-gas and hydro carbon microseepage. Where there is hydrocarbon gas, there is various earth's surface anomalies that can be obtained by remote sensing technique at Present. Based on this Principle, Ladar is a kind of more effective means by direct detecting quantity of significant gas. Combining techniques of Laser and Radar make Lader possess superior distinct property. With continuous development and perfect of Its technique, Ladar has been possible to be used in direct exploration oil and gas resources. In this paper, Ladar system, basic principles and detecting method are presented and applicable feasibility is discussed. To this end. we belive that Ladar is a more powerful tool and must have an extensive applied prospect in the exploration of natural mineral resources as well.
