摘要
文章结合胜利探区地层衰减规律和环境噪音情况、国内外检波器的技术发展及工艺水平现状,针对东营凹陷的高精度地震勘探检波器选型及仪器采集参数的确定展开讨论。建议该区高精度勘探使用频率10Hz或14Hz的速度型超级检波器、组串方式6串2并;SN388仪器前放增益选12dB,入口电压范围为0.40μVRMS^0.40V RMS;采样率选1ms,通频带范围为1Hz^412Hz(最小相位)、1Hz^250Hz(线性相位)时较理想。在辛镇地区应用后取得较好的效果。
The selection of geophone pattern and instrument parameters for the high resolution seismic exploration in Dongying Depression is discussed according to the attenuation and ambient noise in Shengli prospect area and the level of technology of geophone at present. The 10/14 Hz of natural frequency with 6 serial and 2 parallel pattern geophone is ideal for the high resolution seismic exploration in Dongying Depression. The parameters of SN388 are as follows: the preamplifier gain is 12 dB, the entrance pressure is 0.40 μVRMS～0.40 VRMS, the sampling rate is 1 ms, and the transmission band is 1Hz～412Hz of minimum phase and 1 Hz～250 Hz of linear phase. And it has good application effect in Xinzhen oilfield.
