【摘要】 钻井、地震、测井及测试资料综合研究认为:渤海湾盆地济阳—临清东部地区石炭—二叠系主要发育一套浅海碳酸盐岩台地相灰岩、障壁—潟湖、潮坪、沼泽及三角洲相陆源碎屑岩和煤层。从纵向发育的沉积特征来看,上石炭统本溪组发育浅海台地相碳酸盐岩和浅海陆棚相(陆表海)砂泥岩,太原组主要发育障壁—潟湖、潮坪、沼泽相碳酸盐岩、陆源碎屑岩和煤的混合沉积;二叠系山西组主要发育三角洲相和三角洲平原沼泽相砂泥岩及煤,下石盒子组和上石盒子组则以发育近海陆相碎屑岩沉积为主,局部有河流沼泽的泥炭和煤发育。沉积环境总体具有自下而上、由南向北由浅海相、海陆交互相逐步过渡为陆相的基本特点。成煤环境以晚石炭世—早二叠世太原、山西期潮坪、潟湖过渡带之潮坪沼泽环境及三角洲平原沼泽环境为最佳。更多还原

【Abstract】 Drilling,seismic,logging and testing data have indicated that,Carboniferous and Permian in the east of Jiyang and Linqing in the Bohaiwan Basin are mainly composed of a set of neritic carbonate platform facies limestone as well as barrier-lagoon,tidal flat,paludal and deltaic facies terrigenous clastic rock and coal bed.Vertically,in the Benxi Formation of the Upper Carboniferous,neritic carbonate platform facies carbonate rock and neritic continental shelf facies sand/mud stone are generated.In the Taiyuan Formation,a combination of barrier-lagoon,tidal flat,paludal facies carbonate rock,terrigenous clastic rock and coal bed is deposited.In the Shanxi Formation of Permian,deltaic facies and deltaic plane paludal facies sand/mud stone as well as coal are generated.In the Lower and Upper Shihezi Formation,offshore continental facies clastic rock is deposited,and in some places are fluvial paludal peat and coal generated.Sedimentary environment changes from neritic facies,marine/continental facies to continental facies,from bottom to top,south to north.The tidal flat,paludal and the deltaic plane paludal environments during the Taiyuan and Shanxi periods are most favorable for coal generation.更多还原
