摘　　要：介绍了近年来磁法勘探在石油工程 (如井场、输油管线等 )调查中的应用实例和效果分析 ,并从理论上进行了分析和验证。结果表明 ,磁法勘探用于井场调查是一种十分有效的方法 ,特别是当井场周围海底表面或以下存在有铁磁性物体时 ,磁法勘探都能对其进行有效地探测 。In this paper, the cases to apply the magnetic detection to site survey and the effect analysis are introduced, and the theoretic analysis and validation of the applications are also made. It is shown from the survey results that the application of magnetic detection to site survey is a quite effective method, and especially when there are ferromagnetic objects located above or below the sea bottom about the well site, the objects can be probed effectively by using the magnetic detection method, and their positions can also be determined precisely.
