Abstract: The magmatic rock buried-hill gas reservoir in the central uplift zone of northern Songliao Basin is one of the important areas for risk exploration of deep natural gas, and the characteristics and controlling factors of high-quality reservoirs are still unclear, thus severely restricting the gas reservoir exploration process. Based on the drilling, logging, seismic data and analytical test data, this paper analyzes in detail the reservoir characteristics of magmatic rock buried-hill and the controlling factors of high-quality reservoirs in the central uplift zone. The research results show that the magmatic rock buried-hill in the central uplift zone can be vertically divided into weathered accumulation layer, weathering-leaching layer, fracture layer and tight magmatic rock layer, showing the characteristics of reservoirs with low-porosity and ultra-low permeability. The reservoir spaces include the intergranular dissolution pores, intragranular dissolution pores, quartz primary intergranular pores, structural fractures and micro-fractures. The micron and nanoscale pores communicating with micro-fractures can provide storage space for natural gas. The NNW-, NNE-, NE- and NW-trending fractures are mainly developed in the study area, with the medium to high dip angles. Granite and cataclastic granite reservoirs have relatively good physical properties, well-developed fractures, and high degree of fracture opening, and are the dominant lithologies of magmatic rock buried-hill reservoir in the central uplift zone. The controlling factors such as multi-stage structural superposition, weathering leaching, organic acid dissolution, and structural high locations have controlling effects on the development of high-quality reservoirs in magmatic rock buried-hill of the central uplift zone of northern Songliao Basin. The research results provide a reference for promoting the natural gas exploration and development in magmatic rock buried-hills.
