Application of shale gas seismic exploration in butu-zhaojue area, xichang basin
摘要：The Butu-Zhaojue area of Xichang basin is distributed in the southwest margin of Sichuan basin, and belongs to the upper Yangtze region tectonics. The basin has undergone a long and complex evolution process, forming a tectonic pattern of north and south blocks and east and west zones. The geological situation in the basin is complicated. The north-south fault is well developed and the transverse fault is strongly cut. However, the structure in Butuo-Zhaojue area is relatively stable, with only 4 north-south faults developed. Basin is located in the our country the first rung of the Qinghai-tibet plateau Hengduan mountains along the border with the second step in Sichuan basin, strong erosion by rivers, rolling hills, ravines crossbar, showing typical deep cutting-alpine valley geomorphology, seismic geology condition is complicated,exploration facing surface condition and underground complex geological "double". According to the above situation, the jue-ZhaoJiao shale gas seismic exploration area, through the detailed test work, take targeted measures, optimizing acquisition parameters, preliminary formed such complex area of "high, small, low, wide, long" earthquake acquisition observation method and form a complete set of processing technology, has achieved good effect in the practical exploration data.
