新场气田沙溪庙气藏现今的产气井全部落在古构造范围内,说明古构造对气藏分布范围和边界有明显的控制作用。从构造低部位到高部位,天然气中甲烷含量、重烃含量、干燥系数、ΔR3值以及CO2和H2S含量均呈现规律性变化,说明古构造对天然气的运移方向也有很强的控制作用。今构造对古构造虽有较强的破坏作用,但基本上没有改变天然气的分布格局,对天然气的控制作用不明显,仅在局部地区(古今构造高点叠合部位)有所反映。
The gas production wells in Shaximiao gas reservoir in Xinchang gas field all fall within the range of paleostructure, indicating that paleotectonics have significant control over the distribution range and boundaries of gas reservoirs. The methane content, heavy hydrocarbon content, drying coefficient, ΔR3 value and CO2 and H2S contents of natural gas show a regular change from the low part to the high part, indicating that paleotectonics also have strong control over the gas migration direction. Although this structure has a strong destructive effect on Paleo-tectonics, it has basically not changed the distribution pattern of natural gas and has no obvious control over natural gas. It is only reflected in some areas (ancient and modern superimposed parts of structural highs).
