Based on the study of development of gas source faults and cap rocks, active state of fault and formation period of sealing ability, time and space matching relation between gas source faults and cap rocks and its controlling action on gas accumulation in Xujiaweizi Depression were studied. The result shows that the space matching relation between gas source faults and mudstone cap rocks of K1d2 is good, but the space matching relation between gas source faults and volcanic cap rocks on the top of K1yc1 is bad. The time matching relations of gas source faults with mudstone cap rocks of K1d2 and volcanic cap rocks on the top of K1yc1 is good. The space matching relation between gas source faults and cap rocks influences the gas accumulation layer and location, while the time matching relation between gas source faults and cap rocks influences the gas accumulation degree.
