%X There is great oil and gas perspective in the coal series of Carboniferous-Permian in the North China. Up to now where oil and gas is discovered, where shallow intrusive rocks are also drilled. The intrusive rocks are mainly diorite porphyrite and lamprophyre. Hydrocarbon source rocks including coal in the Carboniferous-Permian came into hydrocarbon generation threshold primarily during Triassic and Jurassic, but the oil and gas were not preserved because the accumulation condition was not available. Since Eocene the source rocks have been buried bellow the threshold of second hydrocarbon generation, coal-derived gas and some light oil have been accumulated in the Gubei, Suqiao and Linqing areas. The gas is geochemically special with high ratio of isobutene/butane, high content of cycloparaffin and aromatics, heavy carbon isotope composition. The authors believed that interaction between the intrusive rocks and source rocks impressed the second generation of oil and gas from the coal series, conducted a series of thermal simulation on hydrocarbon generation from the coal sample and from the coal mixed with the diorite porphyrite or with lamprophyre, and discovered that the productions of gaseous hydrocarbon were increased notably, the gaseous hydrocarbon compositions were similar to those produced from the drilling wells. They concluded that the intrusive rocks (such as diorite porphyrite and lamprophyre) involved the hydrocarbon generation from the coal series, and suggested that coal-derived gas exploration on the Carboniferous-Permian should consider the factor of intrusive rocks on hydrocarbon generation from the coal-series source rocks.
