Abstract

The eruption cycle of volcanic rocks based on virtual reality technology is studied to reveal the spatial distribution of volcanic rocks and the genetic relationship between different lithologic assemblages, and effectively guide volcanic exploration. Taking Xujiaweizi fault depression and Yingshan depression in Songliao Basin as the research area, the monocular vision method of virtual reality technology is used to collect data from the study area. Then, the three-dimensional dynamic scene of the study area was constructed. Based on this, combined with the research steps and division basis of the volcanic eruption cycle, the eruption cycle of the volcanic region in the study area is studied. According to the characteristics of volcanic activity, volcanic facies sequence, and rock rhythm combination in Xujiaweizi fault depression, the first and three sections of Yingcheng formation are divided into three eruption periods according to the contact relationship between sedimentary strata and volcanic rocks in the eruptive intermittent period. Y1C1, Y1C2, Y1C3, Y3C1, Y3C2, and Y3C3 are respectively from bottom to top. Yingshan volcanic rocks in Yingshan depression are divided into three cycles and six periods. Each stage has significant stages and differences, and the eruption intensity is different. The overall performance is gradually enhanced, and the internal cycle is characterized by the first strong and then weak.

Summary

Introduction

With the development of oil and gas exploration, volcanic oil and gas reservoirs have become an essential part of oil and gas exploration. Volcanic rocks are complex in rock type, uneven in regional distribution, and fast in lateral lithology. Volcanic oil and gas reservoir exploration technology is a difficult point in petroleum technology research today (Zhu et al, 2017). The volcanic gas reservoirs in the Songliao basin are controlled by space-time matching relationship between source rocks, volcanic traps, and fault transport channels, which provides a basis for finding desirable exploration areas for volcanic rocks. Stages and differences characterize the volcanic eruption, lithology, and structure are complex and diverse, and physical properties are different. Volcanic eruption cycle study can reveal the spatial distribution of volcanic rocks and the genetic relationship among diverse lithologic assemblages, which provides useful guidance for volcanic exploration (Tian et al, 2017)
