Due to the complex surface seismic geological conditions and complex deep seismic wave field and structural characteristics，the overall seismic data signal-to-noise ratio in the southern margin of the Junggar Basin is low，making it difficult to accurately analyze the structure，which has seriously affected the oil and gas exploration process. With the significant breakthrough of the GT1 well in the lower combination，the overall deployment of the area has implemented wide azimuth，wide bandwidth and high density seismic exploration project covering more than 3 800 km² in steps over the past five years. In the seismic data acquisition phase of these exploration projects，a series of targeted technologies have been applied，including surface conglomerate survey techniques，laser radar aerial information—assisted shot points pre-design，and well-seismic mixed source efficient acquisition techniques. These technologies have enabled the annual increase in shot density within the affordable cost range. After several years of integrated technical breakthroughs，the imaging effect of seismic data in this area has been greatly improved，and the well-seismic error has been significantly reduced. The seismic acquisition technology in the dual complex area on the southern margin of the Junggar Basin is of great reference significance for similar seismic acquisition projects in exploration areas.

The southern piedmont belt of Junggar Basin is rich in oil and gas resources. However，seismic exploration is faced with such problems as high implementation difficulties，low efficiency，high risks and high costs of field acquisition，due to the highly undulating surface conditions and complex underground structures. Therefore，the LiDAR technology was introduced to improve quality and efficiency in seismic acquisition. The functions of mountain excitation type division，mountain shot point pre-design，fine surface survey design，mountain vehicle navigation design and risk classification can be rapidly completed through the "far-looking" functionality of LiDAR images and high precision elevation data. With the application of this technology in mountain seismic acquisition，vibroseis has access into mountains，which effectively improves the excitation ratio of vibroseis in mountainous areas and the efficiency of field acquisition operations to improve quality and efficiency in the field. Looking ahead，it is believed that the LiDAR technology will play a greater role in seismic acquisition operations in complex mountainous areas. The high precision coordinates and elevation models of LiDAR images are expected to replace traditional measurement processes in field acquisition. The high resolution coordinates and elevations can improve the accuracy of surface modeling inversion. Rapid construction of digital outcrop models can be delivered with high definition imaging and digital elevation platforms. This technology promotes the upgrading of seismic exploration processes，the implementation of efficient exploration in mountainous areas，and data improvement for complex moutainous structures.
