摘要
The seismic data’s quality is decided by gathering rationality and integrity. The main purpose is that choice reasonable excitation position. In mountainous slop-wash zone,scattering of seismic energy is serious,the shotpoint should be underneath the talus, well completion and cementing of earthquake are difficult, and charge pellet cannot arrive at reasonable position,in view of these actual problems, the authors improve well completion drilling tool and optimize the observation method.
