Characterization Technology and Application of Complex Volcanic Rock Reservoir and Permeability in Kelameili Gas Field

Kelameili gas field is located in the west end of Dinan uplift in the southeast of Luliang uplift in the Junggar Basin. Volcanic gas reservoirs in this area are characterized by complex lithology, rapid spatial change, strong heterogeneity, etc. In recent years, the understanding of structure and reservoir has been deepened in the process of gas reservoir development and production, but it is still difficult to solve the problem of difficult reservoir characterization and inconsistent dynamic and static, which restricts the further development of gas reservoirs. With the gradual improvement of the well network, based on a large amount of well logging, seismic, and production testing data, the technique of combining dynamic and static reservoir characterization has been proposed for the first time. On the one hand, by utilizing static data and integrating well seismic research, a reservoir permeability characterization method is established, which is mainly based on well logging lithology identification and supplemented by waveform clustering seismic attributes; On the other hand, dynamic data is used to distinguish the connectivity between wells, and the control area of a single well is calculated back using the volumetric method. Characterization of Storage and Permeation Bodies by Combining Dynamic and Static Techniques. This provides strong support for the effective utilization of remaining reserves and the improvement of well networks.
