The tectonic setting of the study area was aulacogen in Mesoproterzoic to Early Paleozoic, and impactogen in Late Paleozoic.The lithostrtiagaphic units contain Jingyuan Formation,Yanghugou Formation and Taiyuan Formation during Late Carboniferous in Hulusitai section of Ordos basin.Based on the study of high reselution sequence cycle and depositional systems,sixteen T R high reslution sequence cycles occur from Namurian C stage to Stephanian stage in Late Carboniferous strata.There developped barrier lagoon systems (Jingyuan Fm.and Yanghugou Fm.),barrier lagoon with carbonate platform composite systems (Jingyuan Fm.and Yanghugou Fm.)and tidal delta systems(Taiyan Fm.).They average about 1.9 Ma and range from 1.1~3.3 Ma in length,reflecting forth order relative sea level change cycles,and belong to High resolution Sequence Cycles.Each T R sequence is composed of transgressive system tract,early highstand system tract,later highstand system tract,with a few record of forced regression system tract.In general,lowstand ersional sequence bondary and transgressive surface are merged,with no or few record of the lowstand system tract.Transsion came from Qilian Sea during early middle stage of Late Carboniferous.Qilian Sea and Huabei Sea were merged in Late Taiyuan stage.But they are not coincident with forth order sea level fluctuation.It is charcterizied of forth order sea kevel change by the slow rising firstly and then dast rising with interenvening period of fall,and then fast falling with a few forced regression.The third order sea level change reflects that transgression began in Namurian C stage and reached maxium transgrssion in Wesphalian stage and occoured regression in the end of Carboniferous.So,the relative sea level change from the record of the stratigraphy sequences are the composite sea level change with small order cycles superimposed with high order cycles subsidence and sediment influx.Finally,sequence stratigarphic model of paleocoastal plain environment has been proposed.

鄂尔多斯盆地西缘呼鲁斯太剖面上石炭统包括靖远组、羊虎沟组和太原组,发育有堡岛、堡岛—台地和潮控三角洲三种沉积体系,自下而上可以划分出16 个海进- 海退层序旋回,每个层序旋回的时限为1 .1 ~3 .3 Ma ,平均1 .9 Ma ,相当于四级相对海平面变化旋回,属高频层序旋回。每个层序由海侵体系域和早期高位体系域、晚期高位体系域组成,偶发育有强制海退体系域。晚石炭世早期海侵来自祁连海,太原晚期,祁连海与华北连通。研究区古海平面变化表现为先慢速后快速海侵和快速海退,少数为正常海退,并由此建立了古海岸平原的层序地层模式。

The interaction of tectonics,change of global sea level and climate controlled the sediment supply and the scale of filled accommodation.On the ramp margin of forced regressive background,no by_pass sediments were migrated to basin floor during falling of the relative sea level.However there was a set of descending stepwise wedges known as forced regressive systems tracts in the basin.Donghe sandstone equivalent of Manxi Block in Tarim Basin was distinguished on the sequence boundary (unconformity), and it has...

The interaction of tectonics,change of global sea level and climate controlled the sediment supply and the scale of filled accommodation.On the ramp margin of forced regressive background,no by_pass sediments were migrated to basin floor during falling of the relative sea level.However there was a set of descending stepwise wedges known as forced regressive systems tracts in the basin.Donghe sandstone equivalent of Manxi Block in Tarim Basin was distinguished on the sequence boundary (unconformity), and it has shown iso?_chronology and changes of lithological and litho?_facies in the different places.The sequence SQ1 of Donghe sandstone equivalent was resulted from long_term falling of sea level and reinforced by tectonics.It shows a broadly developed basin_scale unconformity.The development of SQ1 was controlled distinctly by sea level changes.The marine ingressive systems tract was developed during fast rising period of sea level,and the forced regressive systems tract was developed during slow falling of sea level.Donghe sandstone of Manxi Block characterized by forced regressive systems tract was the composite sandstone body on the background of marine regression.The composite sandstone bodies were distributed in very complicated shapes,and most of them were developed in point_shape or cake_shape bodies.The oil_target reservoirs of the sandstone body were mainly distributed on the coastal zone and belonged to the shore face sediments.

构造运动、全球海平面变化和气候的相互作用控制了沉积物供给量以及可容空间被充填的规模。在强制海退情况下的缓坡边缘上 ,相对海平面下降期间过路沉积物未被输送到盆底 ,而被沉积为一组逐级下降的前积楔 ,形成强制海退体系域。塔里木盆地满西区块的东河砂岩等时段是基于东河砂岩段上部和下部所存在的层序界面 (不整合面 )而划分的 ,具有等时性 ,但岩性、岩相在不同位置、不同地区会有变化。东河砂岩等时段所属的层序SQ 1的层序界面是海平面长期下降的结果 ,并受到构造运动的加强作用 ,表现为一个盆地范围内广泛发育的不整合面。层序SQ 1的发育演化明显受到海平面变化的控制 :在海平面快速上升时期发育海侵体系域 ;在海平面缓慢下降时期发育强制海退体系域。满西地区的东河砂岩是强制海退体系域的沉积产物 ,是在海退背景下发育的复合砂体 ,其展布非常复杂 ,多数呈点状或块状展布。层序SQ1的油气储集体主要分布于海岸带附近 ,它们是前滨—临滨沉积砂体。

The concept of forced regression and its significance for traditional sequence stratigraphy have been generally reviewed by the authors during this study. The feasibility of quartation for system tract and main sedimentary characteristics of forced regression system tract have been discussed, based on the new advances in researches on forced regressive deposits at home and abroad.
