川中公山廟地區(qū)高密度三維地震勘探資料采集方案與應用
[Abstract]:With the development of seismic exploration technology, the requirement of precision is also increasing, and conventional 3D seismic exploration has been unable to meet the requirements of geological tasks. Taking the Gongshanmiao area of Sichuan Basin as an example, the region is rich in oil and gas resources. In the past ten years, many rounds of seismic exploration projects have been deployed, and the results obtained support the deployment of more than 80 oil wells in this area. But because the reservoir is thin and the reservoir formation is controlled by fractures and pores, the conventional seismic technique can not completely solve the problem of exploration and development in this area, which to a great extent limits the progress of exploration and development of Jurassic reservoirs in central Sichuan. Therefore, it is urgent to carry out new research on seismic technology, break through the technical bottleneck of existing conventional earthquakes, and further enhance the ability of seismic data to depict fine structures. Therefore, as a new technique which can effectively improve the accuracy of seismic data, high density 3D seismic technology has been applied in Gongshanmiao area. Through the detailed investigation and analysis of the characteristics and application examples of high-density seismic acquisition technology, the main achievements are as follows: it is clear that the core idea of the technology is to no longer distinguish the interference wave from the effective wave in the acquisition stage. The seismic signal is sampled with full wave field nondestructive sampling, which has the characteristics of single point excitation, single point receiving, small plane, wide azimuth, etc. The effect of the pertinence technology used in indoor processing is discussed. Through theoretical research and practical data comparison, it shows its advantages in improving the accuracy of seismic data and depicting fine structures, which indicates that the high-density seismic acquisition technology has a good application prospect in Gongshanmiao area. After considering its application effect and technical characteristics, some reasonable suggestions are put forward for the application of high-density seismic exploration technology in the future.
