摘要
随钻VSP是制用钻井过程中旋转钻头与地层摩擦产生的振动作为井下震源,进行VSP资料采集的一项新技术。为了应用和推广这一新技术,我们做了随钻VSP模拟试验,即地表浅层炮井随钻地震速度测量。文中介绍了随钻VSP模拟试验的方法、仪器设备及其功能和试验的效果。
VSP in drilling is a new technique that collects VSP data by taking as a downhole source the vibration created because the revolving bit acts upon formation.In order to spread this technique,I have made trial VSP modeling during shothole drilling: shallow seismic velocity survey during shothole drilling.The article sketches out the procedure for trial VSP modeling during drilling,the involved instruments and their functions,and the trial effect.
