In this paper , the author synthetically applied continental lake basin high - resolution sequence stratigraphy , sedimentation , well logging , petroleum geology , mathematics geology , etc , on the basis of studying on the core of the well drilling in the district , fully utilize logging well , well drilling core and testing and analyzing materials , adopting well logging - sedimentary facies automatical identification to study the characters of sedimentary facies and sub - facies further . and study sedimentary facies profoundly , and carry on sedimentary facies contrast well to well , to study yanchang 3 sector and yanchang 4 + 5 sector lithofacies palaeogeography character and evolution further 本文综合应用陆相盆地高分辨率层序地层学、沉积学、测井学、石油地质学、数学地质等理论，在对研究区内有关钻井岩芯观察的基础上，充分利用测井、钻井岩芯以及测试分析资料，并采用测井?沉积相自动识别等方法，深入研究了沉积相、沉积微相特征，并进行井间沉积相对比，进而探讨了长3 、长4 + 5期的岩相古地理特征及其演化。
In this paper , the authors prove the sedimentary environment of every lithostratigraphic unit of devonian , and precisely divide the geomorphic units of petrologic paleogeography of that period , based on the multiple division and detailed study to the petrostratigraphy , biostrtigraphy and sequence stratigraphy of devonian in hubei and its adjacent provinces 摘要通过对湖北及邻省泥盆纪岩石地层、生物地层与层序地层进行多重划分对比和详细研究，以大量实际资料确定该时期各岩石地层单位的沉积环境，准确划分出该时期岩相古地理地貌单元。
According to sedimentary characteristics of the carboniferous taiyuan formation in feicheng coal field , including lithology , size distribution , sedimenta ry structure , geochemistry and paleontology etc . , the carboniferous paleoenvironme nt of this area is divided into carbonate open platform and tidal flat environme nt . it is recognized that the taiyuan formation is formed in the epicontinental c oast which is dominated by the tidal . the peat flat is the important paleoenviron ment for coal accumulation . the tidal channel destroys the coal bed . the pulsative vibration of the crust is the major factor which controls the evolution of the sedimentary environment and the coal accumulation 根据肥城煤田石炭系太原组的岩性、粒度分布、沉积构造、地球化学及古生物等沉积特征，将该区晚石炭世古地理划分为碳酸盐开阔台地和潮坪环境，认为太原组形成于潮汐作用为主的陆表海海岸，泥炭坪是成煤的重要古地理环境，潮渠对煤层有一定的破坏作用，地壳的脉动性振荡作用是控制沉积环境演化和聚煤作用的主要因素。
Yanchang 4 + 5 sector to yanchang 3 sector lithofacies palaeogeography pattern was stable , because the constitution background was steady , and the source direction had no change , and supply was abundant . in those sectors the basin development was in lake retreat , and in the period of extinction gradually , and formatted construction delta deposit , but in yanchang 33 period the sedimentary speed were greater than construction speed , showing that overriding river mouth bars were abundant 长4 + 5 ?长3期湖盆发展处于湖退、萎缩逐渐消亡时期，由于构造背景稳定，物源来源方向没有变化，物源供给充分，所以岩相古地理格局基本一致，形成建设性三角洲沉积，但长3 ~ 3期沉积速率大于构造沉降速率，表现为叠置河口砂坝极其发育。
Abstract : sequence - paleogeographic mapping is to use information gained from integrated pa leogeographic and sequence stratigraphic studies to produce a synchronic or inst antaneous lithofacies - paleogeographic diagram , in which the recognized key bound ary - surfaces , sequences and system tracks are taken as mapping units 文摘:层序-岩相古地理编图就是将岩相古地理的研究和编图与层序地层学的研究紧密结合，利用层序界面和其它关键界面，以体系域、层序或等时界面为编图单元编制等时或瞬时岩相古地理图。
