Abstract: A drill-bit seismic method where the seismic receivers are located in the BHA. The data detected by these receivers is processed by a downhole processing unit in order to estimate the interval velocity of the seismic wave between the sensors and between the bit and a sensor. Additionally, the processed data might provide the distance to a seismic reflector close to the borehole and the average seismic velocity between the well and this reflector. The processed data can be transmitted to surface location by mud-pulse telemetry. The pilot signal can be also used to process seismic data recorded by receivers located at the earth surface (or close to it).

Abstract translation: 地震接收机位于BHA中的钻头地震方法。 这些接收机检测到的数据由井下处理单元进行处理，以估计传感器之间和位与传感器之间的地震波的间隔速度。 另外，经处理的数据可以提供靠近钻孔的地震反射器的距离以及井与该反射器之间的平均地震速度。 处理后的数据可以通过泥浆脉冲遥测传输到地面位置。 导频信号还可用于处理位于地表（或靠近地面）的接收机记录的地震数据。
