摘要
根据以往三维地震勘探在村镇条件下存在的问题,提出了有效提高村镇区域内地震采集工作效率与质量的方法和措施:采用密集检波器接收,炮点微调、增加炮数以及开动大排列的方法来保证地下反射点的叠加次数;采用聚能弹激发,增强有效信号,避免或减少对村镇内建筑物的破坏;选择噪音较小的时段施工,避免干扰信息;对检波器采用石膏固化法埋置。
In allusion to issues existed in town and village thick zone 3D seismic prospecting, put forward methods and measures to improve data acquisition efficiency and quality effectively： using close-spaced geophone receiving, shot-point fine adjustment, shot number increasing and lengthening arrangement to ensure stacking fold of reflection point; using shaped-charge shot to enhance effective signal, prevent or reduce building destruction in towns and villages; operating within time-span with less noise to avoid interferences; gypsum cementation of geophone setting to improve coupling between geophone and ground to improve seismic recording quality.
