为了在东海陆架盆地中寻找煤炭和油气资源,以层序地层学、煤田地质学为指导,结合构造地质学、沉积学的相关理论,探讨了东海陆架断陷盆地形成过程中的聚煤模式。结果表明:东海陆架盆地含煤建造的沉积类型众多,沉积环境具有多样性。总体上北部以陆相含煤建造为主;南部以滨海相和海陆过渡相为主。煤层具有多相带,多煤层中心展布的格局。区域构造格架、构造背景控制着断陷盆地形成发展过程的聚煤作用,沉积构造控制着聚煤盆地的构造格架与聚煤作用。

In order to explore coal and oil-gas renounces in the East China Sea shelf basin, based on the sequence stratigraphy and the coalfield geology as the gu ide, in combination with the structural geology and sedimentology related theory, the coal-accumulation model in the formation process of theEast China Sea shelf fault depression basin was discussed.The results showed that there were many types of sedimentary coal bearing structures in East China Sea Basin and the sedimentary e nvironment with variety.Generally there was a continental facies coal bearing structure mainly in the north and there was lttoral facies and marine & terrestrial transition facies mainly in the south.The seams would have multi facies zone and would be in a pattern of a multi seam central distribution.The regional structure frame and the st ructure background controlled the coal-accumulation function of the fault depression basin formation and development process.And the sedimentary structure controlled the structure frame and coal-accumulation function of the coal-accumulation basin.
