Abstract：Geological conditions of the mountainous area in Block 71 of Yemen are very complex. The surface of the mountain is covered with thin weathering layer in some places, and the excitation condition is bad. Therefore, the key point of improving the seismic data quality is to optimize the data quality of the mountainous area. The direction and method of optimizing the vitalizing technology was determined through analyzing the former seismic data, and the parameters for dynamite and Vibroseis were decided respectively through comprehensive parameter test. Vibroseis was adopted in the open and wide area and dynamite source was used as supplement where the vacant source points were excessive. Single-line design was performed after scouting the line by means of performing crooked line and changing geometry so as to design as many source points for vibroseis as possible during the real operation. With the new exciting technique, the data quality has been improved greatly.
