Process Simulation of Carboniferous Volcanic in Jinlong Area, Junggar Basin

Abstract:

The Jinlong area is located in the northwestern margin of Junggar Basin. Volcanic is widely distributed in Carboniferous layers, showing well petroleum resources prospects. The distribution of volcanic reservoirs is obviously controlled by the distribution characteristics of volcanic lithofacies. Therefore, through the analysis of core observation, thin section identification, data of well logging and mud logging, and interpretation of seismic data, this paper studies process simulation of Carboniferous volcanic in the Jinlong area, which is located in the northwestern margin of Junggar Basin. Based on the characteristics of volcanic materials and comparison of profile facies, the paper restores distribution characteristics of lithofacies of Carboniferous in the study area: The study area mainly develops volcanic lithofacies such as effusive phase and explosive phase. The thickness between wells varies greatly, which is affected by eruption mode and fault development. The vertical and horizontal changes of lithofacies are discontinuous and the phase transformation is fast. The volcanic activity of Carboniferous gradually weakened. There are multiple volcanic eruption centers in each period, which are controlled by crack and distributed in beads. In addition, an intermediate-mafic composite volcanic-crack eruption edifice was developed in the southern zone of the study area. Because of strong tectonism in the area near the crater, there are many dissolvable components in volcanic, which can form favorable hydrocarbon reservoir bodies and become the most favorable target zone in the Jinlong area.
