摘要
本文根据岩性组合、测井曲线和沉积标志,研究了菏泽地区晚古生代含煤地层沉积环境,将研究区划分为四类沉积体系:潮坪沉积体系、障壁-泻湖沉积体系、河控浅水三角洲沉积体系、河流-湖泊复合沉积体系。该研究区经过水下三角洲平原、边缘三角洲潮汐平原、边缘三角洲沼泽平原、下三角洲平原、上三角洲平原五个演化过程。
Based on lithologic combination, logging curve and sedimentary marks, this paper studied sedimentary environment of Late Paleozoic Coal-bearing strata in Heze district, and the study area is divided into four main sedimentary systems： tidal flat depositional system, barrier-lagoon depositional system, fluvial-dominated, shallow water deltaic depositional system and fluvial-lacustrine depositional system. The sedimentary environment experienced five sedimentary stages,that is,under water delta plain, marginal delta plain, marginal delta tidal plain, low delta plain and up delta plain, which generally formed a progradational sequence.
