With the development and prosperity of the oil industry, our country put more and more power to increase the strength in the aspect of exploration. In order to continuously increase our reserves of oil and gas resources, further expanding exploratory areas, the geophysical exploration workers of our country have shift their attentions from the eastern region to the western region gradually. The western hold the very rich oil and gas resources, especially in Junggar Basin. It is the most important position of exploration in oil and gas resources, and it has become a major region of resource exploration. The Junggar Basin is a typical oil and gas exploration in complex areas in our country. It has varied topography and complex surface structure. The fracture development and the formation dip Angle is big. Seismic wave field is more complex and strong interference waves. All of these factors are leads to the low signal to noise ratio of seismic data. As well as surface consistency poorly, statics problem prominent, complicated structure, imaging difficultly. To solve these problems, we should combined with the actual situation, and then further looking for an effective method for seismic data processing. It will help to improve and accelerate the process of resource exploration in Junggar Basin.In this paper, we mainly discuss and research acquired seismic data, analyze data characteristics. Focusing on the methods of wavelet processing, static correction, improve the signal to noise ratio, and other key technologies. We hope to solve problem with those techniques, then improve seismic signal. We take on the basis of data analysis, and make good selection of processing parameters, then optimize the process. Pay attention to denoising in prestack, static correction, deconvolution, velocity analysis, migration imaging, etc. With those techniques, improve and perfect the processing method, further put forward good measures to resolve a series of problems. Established static correction processing technology, and improve related theories, and applied to this study region. Find the advantages and disadvantages. Eventually we gain the good results of seismic data processing.
