Abstract

Abstract:

The development of high-quality shale in Wufeng-Longmaxi formation in Wulong area is characterized by wide distribution, large thickness, moderate burial depth, high organic matter abundance and moderate thermal evolution. It is a favorable shale gas exploration area. Due to the typical southern China’s mountainous landform in Wulong and the influence of large obstacles such as Wujiang river and nearby towns, the explosive source is limited, resulting in the emergence of the so-called “data skylight”. The advantages of seismic wave generated by the spark source, such as the rich high-frequency information, good waveform repeatability, good time consistency, safe and free from contamination, meet the source requirements for seismic exploration in the Wulong area. After the application of spark source, the coverage fold of large obstacle area increases and the section gap decreases. The energy of the spark source is 200 ~ 800 kJ, which is equivalent to the energy of the 2 ~ 4 kg well gun（14 kg, 21 m）. A high quality reflection signal can be seen above 2 s of the single shot record, and the effective frequency band is up to 80 Hz. The spark source can effectively make up for the “data skylight” in Wulong and Tukan town, and meet the requirements of 3D geological exploration.

Key words: mountains in southern China, shale gas, data skylight, spark source, effect analysis
