Analysis Of Volcanic Reservoir Characteristics In Liaohe Periphery Basins

Volcanic rocks are widely distributed in Liaohe Periphery Basins, and a lot of basins have the reservoir conditions for the formation of volcanic rocks.But so far only Long Wantong Depression and Zhang Qiang Depression discovered volcanic reservoir, and carried out on the volcanic reservoir more detailed study. For systematic analysis of the reservoir characteristics of volcanic rocks in Liaohe Periphery Basins, and better at looking for the volcanic reservoir in there, this article from the geotectonic setting and regional structural characteristics and sedimentary basin evolution started, analysis of the structure caused by the volcanic eruption of factors, volcanic rocks of the regional background deposition, the distribution of volcanic rocks and lithological characteristics. And volcanic cited research at home and abroad to drum Long Wantong Depression and Zhang Qiang Depression, described in detail the volcanic reservoir and reservoir characteristics in Liaohe Periphery Basins.In the course of the application of plate tectonic theory and the theory of Liaohe Periphery Basins, where the structure position of the tectonic framework and basin formation, evolution and post-transformation and the role of different types of volcanoes and magma intrusion occurred in the relationship between role. Application of tectono-stratigraphic analysis and structural dynamics of Liaohe Periphery Basins, the structure pattern, regional location and characteristics of sedimentary evolution of the distribution of volcanic rocks and the effects of lithology. Through the stratigraphy, sedimentary facies, rock chemistry research, summed up the volcanic rock types and lithologic features of Liaohe Periphery Basins.After the study of volcanic reservoir characteristics in Long Wantong Depression, an analysis of volcanic rock types and reservoir performance, summed up the volcanic eruption model and the type of volcanic lithofacies of Long Wantong Depression. Reservoir characteristics through analysis of Long Wantong Depression reservoir is volcanic reservoir lithology. Volcanic rocks of the main elements of a comprehensive analysis and rare earth elements identified Zhang Qiang Depression volcanic rocks formed by volcanic rock types and tectonic settings. Application of sedimentology and petrology Zhang Qiang Depression theory of volcanic reservoir space and nature, a detailed analysis of the accumulation of volcanic reservoir control factors. There have a more systematic, comprehensive awareness to the volcanic reservoir of Zhang Qiang Depression.According to the research results, that the volcanic rocks in Liaohe Periphery Basins exploration should be the focus to Long Wantong Depression and Zhang Qiang Depression. As the goal, drawing on the two sunken volcanic reservoir exploration of the successful experience of depression in the search for other similar volcanic reservoir . With the geological theory and the continuous development of exploration technology, , there will find more volcanic reservoir in Liaohe Periphery Basins, which is the focus of future research areas of exploration in Liaohe Periphery Basins.
