东海陆架盆地油气勘探和研究表明，中生界具备一定的油气勘探前景。根据近年来采集的二维地震资料，结合邻区地质资料，对东海陆架盆地南部中生代地层、烃源条件、储盖条件和含油气系统进行了初步分析评价，认为中生界在本地区分布广、厚度大，发育中—下侏罗统海相烃源岩和下白垩统海侵湖相烃源岩，具备一定的油气勘探潜力。

The present research and exploration conducted in East China Sea Shelf Basin indicate that the Mesozoic has exploration potentials. Based on 2D seismic data acquired in recently and regional geological data, theauthor made a preliminary evaluation the formation, hydrocarbon source condition, reservoir-cap condition and petroleum system in the Mesozoic of the Southern East China Sea Shelf Basin. The results indicate that Mesozoic strata are widely distributed and well developed, with Marine hydrocarbon source rocks in the Lower and Middle Jurassic, as well as the transgression lacustrine hydrocarbon source rocks in Lower Cretaceous. Mesozoic basin of this area has potential for hydrocarbon exploration.
