摘要
Volcanic rocks are characterized by complex structure, rapid change of lithology and facies, and strong heterogeneity of reservoirs, thus geologic modeling is very hard. Based on the experiences of the geologic modeling of the volcanic reservoirs in the Xushen gas field, the authors carried out the geologic modeling of the volcanic reservoirs in the Songnan gas field, Songliao Basin. The study results, in combination with those of the comprehensive geologic research, were utilized to build structural models and attribute models of the study area. The results have also been validated by the follow-up development drilling. It provided a strong foundation for strategic decision making of gas field development.
