[Abstract]:In recent years, the exploration of natural gas in the deep water area of the Southeast qiongnan basin of the South China Sea has made a major breakthrough. The first self exploration of the deep water field, Lingshui 17-2 gas field, is found in our country. However, in the description of the gas reservoir in the deep water gas field, the sand body deposition model is still complicated, the portrayed sand body is difficult, the lateral velocity of the formation is changed greatly and the structure falls. In order to improve the accuracy of the description of the deep water gas reservoir and to accurately evaluate the reserves of the deep water gas reservoir, this paper, based on the three key key technology in the description of the deep water gas reservoir, has solved the gas reservoir in the deep water area in order to improve the accuracy of the description of the deep water gas reservoir and accurately evaluate the reserves of the deep water gas reservoir. The paper, based on the Lingshui 17-2 gas field reserve research project, has studied the deep water reservoir description. The description of sand body and waterway portrayed, time depth conversion, reservoir and gas bearing prediction. In view of the problems of multi sand body deposition, multi channel erosion, complex sedimentary model and difficult sand body characterization in deep water area, first of all, it is guided by regional depositional law, combined with seismic coherent slice and frequency fusion section interpretation to carry out large scale. On the basis of the portrayal of Canyon and waterway, the description of sand body under small scale is carried out, micro interpretation is guided by macro law, the spatial form of Canyon and waterway constrains the interpretation range of each sand body, and the fine depiction of sand body is carried out by the full three-dimensional visual seismic interpretation technology, and the vertical and horizontal direction of the sand body and the waterway in the deep water area is accurately implemented. In order to solve the difficult problem of transversal velocity anomaly in deep water area and difficult time depth conversion, a variety of time depth conversion methods commonly used in the industry are compared. On the basis of implementing the law of formation velocity in deep water, the applicability of various time depth conversion methods in the deep water area is analyzed, and the method of velocity body modeling is selected as the time to apply to the deep water area. Deep conversion method. Based on the speed body modeling method, the optimization method of velocity body and the details of speed modeling are studied. On the basis of speed body optimization, the quality of speed body is optimized by median filtering algorithm on the basis of the analysis of the original speed quality, and the optimal filter window and filter times are optimized. In the field of velocity modeling, the optimization study of the modeling layer is carried out. According to the characteristics of the tectonic deposition in the area, the optimal model control layer is selected. Finally, the time depth conversion of each sand body is completed by the speed model obtained by high precision modeling, the real structure of the underground sand body is reduced, and the method of cross well verification is used to analyze the method. In view of the low number of drilling in deep water and the difficult problem of reservoir prediction and gas bearing prediction caused by insufficient well control, starting with the analysis of the physical characteristics of drilling rock, the reservoir prediction research based on pre stack inversion is carried out, and the reservoir inversion results are used in combination with the sedimentary recognition and drilling Statistics Law on the plane. The transverse distribution characteristics of sand body and the spatial distribution law of reservoir physical property are predicted. On the basis of reservoir implementation, the gas bearing prediction research based on the semi quantitative to quantitative gas prediction based on amplitude analysis is carried out based on the spectral decomposition technique, and the multi angle prediction results are combined to predict the gas bearing boundary of the sand body, and the structure is described with the structure. The gas range of the sand body is verified by cross validation, and the gas range of each sand body is carried out accurately. After this study, the fine depiction of sand body, the implementation of time depth conversion method, the reservoir and gas bearing prediction are solved. The technology of velocity body optimization based on median filtering and the high precision speed modeling technique of well controlled layer control are first applied. The technique is applied to the deep depth conversion in the deep water area; the reservoir and reservoir distribution of the turbidite sand body are accurately predicted by the gas prediction research combined with amplitude quantification, spectral decomposition and attribute analysis in the deep water area for the first time. The results provide a reliable data basis for the reserves evaluation of Lingshui 17-2 gas field in the first self operated deepwater atmosphere field. This provides effective technical reference for the ongoing exploration of deep sea natural gas in China Sea oil.
