摘　　要：钻头随钻地震技术是利用钻井过程中钻头冲击地层产生的振动作为震源的井中勘探技术.它凭借不中断钻井作业这一特点,可以实现连续的逆垂直地震剖面(Reverse Vertical Seismic Profile,RVSP)测量,以达到实时监测钻头位置、预测钻头前方地层地质参数、前瞻成像等目的.钻头随钻地震的本质是RVSP技术,因此本文通过常规RVSP技术引出钻头随钻地震,对钻头随钻地震的基本原理、采集技术和处理技术的优化进行重点介绍,并简单介绍部分应用实例.最后结合钻头随钻地震的优势和局限对其未来的发展方向做出展望.The Drill Bit Seismic While Drilling(DB-SWD)is an in-well exploration technology that uses the vibration generated by the drill bit as seismic source during the operations.Through the continuous drilling,the DB-SWD can acquire real-time Reverse Vertical Seismic Profile(RVSP)records.Furthermore,the DB-SWD determines the drill-bit location,predicts the formation characteristics ahead of the drill-bit position,and performs prospective imaging,among others.This article covers the DB-SWD basic principles,acquisition and processing optimization,as well as some real case applications.Finally,we explore the advantages and limitations of the method,and evaluate its direction for further development.
