摘要:

依据109组水化学数据和31条地球物理探测剖面资料,结合钻孔地层岩性、电测井曲线等资料,对莱州湾南岸海(咸)水入侵界线进行了勘查,结果表明:水化学与地球物理结合的勘查方法对海(咸)水入侵探测效果良好;目前,海(咸)水入侵界线位于台头镇-田柳镇-侯镇-固堤镇-柳疃镇一线;准三维地球物理组合剖面能较好反映咸淡水体在空间上的分布特征,是今后海(咸)水入侵勘查的一种重要方法。

Abstract:

Saltwater intrusion interface was measured according to 109 water samples and 31 geophysical profiles based on lithology and well logging data. The results show that: it reached a good effect on saltwater intrusion measurement with hydro-chemical and geophysical methods; the present intrusion interface was located along a line around Taitou-Tianliu-Houzhen-Gudi-Liutuan towns; saltwater and freshwater bodies were better showed on the combined pre-3D profiles through high-density method which provided a good idea on further study.

Key words: saltwater intrusion, hydrochemistry, geophysics, Laizhou Bay
