地震勘探中表层低速带测定方法探讨

【摘要】 地震勘探中,表层低速带对地下反射波有较大影响,为消除影响就要了解表层速度,因此就要用多种方法来对表层低速带进行测定,提供表层低速带参数,提高静较正质量。在实际地质情况下要用综合方法测定低速带,地震微测井和新的小折射方法是目前应用较多的两种方法,也取得了一定的效果。更多还原

【Abstract】 Seismic exploration,surface low velocity zone on the ground floor reflected wave with considerable influence,we should understand the impact of the elimination of the surface velocity and therefore needs to be used on a variety of methods to determine the surface low velocity zone,the surface low velocity zone to provide parameters to enhance the quality is more static.The actual geological conditions of use of integrated approach to determinate low-speed zone,seismic micro-logging and new small refraction method is the application of more two methods,and achieved some success.更多还原
