Surface geological conditions are very complex in Block 71 of Yemen. The special seismic condition of this area has brought about technical difficulties in construction. In this paper, the author investigated the method of seismic data acquisition in Block 71 through analyzing geophysical conditions and tasks as well as data available and, exemplified by the project of 2D seismic data acquisition in 2006, demonstrated that the adoption of such measures as mixed sources, crooked and linear lines, observation system and excitation parameters could improve the data quality.
