摘要
海底自然烃渗漏在海洋表面形成的油膜分布对海上油气勘探具有重要指示意义。本文利用3 m分辨率的RadarSAT-2数据在渤海海域开展海洋表面油膜检测同步现场试验,利用机油在海面生成表面油膜,14 min后接收SAR数据,测量并分析海洋表面油膜雷达响应特征。试验结果表明,在适合海况条件下,3 m分辨率SAR数据可以检测到几个微米厚度的表面油膜,此时C波段对海洋表面波有5 dB的阻尼作用。油膜漂移的SAR测量结果进一步证实表面油膜的扩散与漂移受风场、流场影响。
The distribution of natural marine hydrocarbon seepage has great significance for the early stage offshore petroleum exploration. In this paper, a satellite synchronous observation experiment was made. oil slick was made with machine oil and imaged by RadarSAT- 2 SAR data after 14 minutes. Some conclusions have been reached： under a certain suitable sea condition, it is possible for SAR data with resolution of 3 meters to detect oil slick with the thickness of several micron meters, and there is 5 dB relative damping on sea surface wave in this case; SAR measurements can further confirm the influence of wind and current condition on the evolution of oil slick.
