摘要
常规海上钻探工作不仅工期长、难度大,往往受成本限制不能布置太多数量的钻孔,而且钻探方法只能揭露钻探点的地层情况,不能推断整个工区海域地层分布情况。为了辅助对海上风电场工程进行地质勘探,通过某海上风电场工程实例介绍利用浅地层剖面法对工区海域进行地层探测,查明工区海域内地层分层、古河道分布和基岩面埋深等。通过与钻探资料对比,结果表明,浅地层剖面法取得了较好的探测效果,为海上地质勘探提供了一种快捷、低成本、准确的物探技术手段。
Conventional offshore drilling not only has a long construction period and great difficulty,but also can not arrange too many boreholes due to cost constraints.Moreover,the drilling method can only reveal the stratum at the drilling points and can not infer the stratum distribution in the whole work area.In order to assist the geological exploration of an offshore wind farm project,through an example of a offshore wind farm project,this paper introduces the stratigraphic exploration of the sea area in the work area by using sub-bottom profiler method to find out the stratum stratification,ancient river distribution and bedrock surface depth.Compared with drilling data,the results show that the sub-bottom profiler method has achieved good detection effect,which provides a fast,low-cost and accurate geophysical prospecting technology for offshore geological exploration.
