Abstract: The three-dimensional graph of proved oil and gas reserves can reflect the spatial distribution of oil and gas reservoirs, which is an important part of the three-dimensional “one map” of natural resources, and provides important support for the management and decision-making of oil and gas mineral resources. Four kinds of three-dimensional graphic representation methods are proposed, including oil and gas area + well location + structural line, oil and gas area + well location, oil and gas area + structural line, well location + structural line. Among them, oil and gas area + well location + structural line is suitable for oil and gas fields with stratified data of oil and gas area and rich drilling data and regional structural research data; oil and gas area + well location is applicable to oil and gas fields with stratified data of oil and gas area, complex regional structure but rich drilling data; oil and gas area + structural line is applicable to oil and gas fields with oil and gas bearing area layering data and rich regional structure research data but lacking drilling data; well location + structure line is applicable to oil and gas fields without oil and gas area data, but with well location and structure line data. In the actual operation process, according to the oil and gas field data, combined with the type of oil and gas reservoir and the overlaying relationship of vertical strata, the appropriate characterization method is selected. This study is of great significance for clarifying the spatial relationship between oil and gas mineral resources and various protected areas, and comprehensively grasping the supply capacity and development and utilization potential of oil and gas resources.
