摘　　要：为探讨东海南部中生代油气勘探前景,开展了东海及邻近陆域中生代油气勘探现状、区域构造和烃源岩条件等对比分析。结果显示,海陆中生代深部地质结构存在较大差异,二者在中生代地层分布的面积与厚度、岩浆岩的分布与强度以及烃源岩条件等方面均表现出明显的不同。综合分析认为,海域中生代构造更稳定、地层分布更广、厚度更大、烃源岩条件更好,因而推测其具有好的油气勘探前景。For discussion on the Mesozoic hydrocarbon potential of Sourthern East China Sea （SECS）,we made the comparative analysis on the hydrocarbon exploration situation,regional tectonics and source rock conditions between SECS and its adjacent terrestrial areas.The results show that Mesozoic deep geological structure has big differences between the offshore and the onshore.They have obvious differences of the Mesozoic strata in distribution and thickness,of igneous rocks in distribution and activity intensity,and of source rock conditions.In terms of comprehensive analysis,it is concluded that the offshore Mesozoic tectonic movement is more stable,the strata are more widespread and larger in thickness,and the source rock conditions are much better.Therefore,the Mesozoic offshore hydrocarbon potential could be better than that of onshore in the SECS.
