چکیده
It’s very important in the seismic operations, amount of charge and pattern of the wells and also vibration energy source parameters. Therefore, will be investigated these parameters usually at the beginning of the project and or sometimes due to the complexity of the geology in the area, during the various steps of seismic and the known as operational field testing. In the field testing, will be investigated land response to waves generated by the energy source and being basic of work, the most optimum mode of charge, depth and pattern of the wells and vibration parameters to achieving the appropriate ratio of the signal to noise (S/N). In this study, selected the middle part of a seismic project for testing and two locations of mountainous and flat for drilling energy sources and data recording. Become spread receivers used over 3 lines and with 319 points on the limited area of the project and recorded and aquisited data by recording system. Finally, depth of 10 meters by charging 19 kg is amount of suggested for the minimum depth and charging as the dynamite energy source parameters. It is worth noting in many cases, frequency waves ground roll is less than 19 Hz that simply can be removed from data in during of the processing.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
