【摘要】 针对油田城镇区地上和地下设施多、炮检点难以布设、井炮震源无法施工、近地表改造严重等特 点,采用探地雷达剖析近地表结构,优选激发和接收条件;井炮震源和可控震源联合施工、井炮垂直叠 加办法改善激发效果;加密检波线、检波器地面和下井联合接收的办法改善接收效果;合理布设炮检点、 适当加密炮点改善观测效果。获取了高信噪比和高精度地震资料。更多还原

【Abstract】 In consideration of tne cnaracteristics of many suriace ana grouna iacinties, onset points being hard to be arranged, the source being hard to be operated and severe surface reconstruction in the towns of oilfields. A surface detecting radar is used to analyze the surface structure, optimal excitation and receiving conditions are used. Offset source is combined with controllable source in operation and vertical stack is used to improve the excitation effect, infill geophone line, receiving by combination of geophone surface and downhole receiving are used to improve the receiving effect. The observation effect is improved by rational arrangement of offset points and proper infill of shot point, by which high precision seismic data of high signal to noise ratio are obtained.更多还原
