| 1. | It include three systems tracts . respectively , the systems tracts are lowstand systems tract , transgressive systems tract and highstand systems tract
型层序包括三个体系域，分别为：低位体系域、水进体系域和高位体系域。 |
| 2. | Better reservoirs are developed in lowstand systems tracts while better source beds and cap rocks are developed in transgressive and highstand systems tracts
低位体系域发育分选良好的储层，而水进体系域和高位体系域沉积则往往是良好的生油层和盖层。 |
| 3. | This prograding complex consists of several small prograding bodies . the transgressive system tract is consist of three retrogradational parasequence sets . the highstand system tract is mainly about aggradation
层序低位域是在强制性湖退背景下形成的，由三个进积型准层序组构成。 |
| 4. | The sequence corresponds to the upper submember of member of shahejie formation ( forminglow - stand system tracts , water transgressionsystem tracts and highstand system tracts ) is a complete cycle
其中，层序相当于河街组四段上亚段，发育低水位体系域、湖侵体系域和高水位体系域，是一个完整的旋回。 |
| 5. | The sequence represents the lower sub - member of member of shahejie formation , characterized by lowstand system tracts undeveloped , only lacustrine transgressionsystem tracts and highstand system tracts developed
层序代表的是沙三段下亚段沉积，低位体系域不发育，只发育湖侵体系域和高水位体系域。 |
| 6. | Lowstand system tract , transgressive system tract and highstand system tract are all have characteristic of changing gradually in tune and space . it ' s the new theory of sequence stratigraphy applying on the continental sedimentary basin
低水位、水进及高水位体系域都具有时间、空间渐变的特征，这是层序地层学理论应用于陆相沉积盆地的新认识。 |
| 7. | From the beginning of sq9 ' s development , the sedimentary environment turn to be lake basin bog . with water becoming shallow , coal seam appeared in lowstand system tract , delta plain and delta front are the main sedimentary bodies in highstand system tract
从层序9开始，水体开始变浅，向湖沼环境过渡，低水位体系域和水进体系域出现了煤线，高水位体系域以三角洲平原及三角洲前缘沉积为主。 |
| 8. | Lowstand fans and lowstand wedges formed in lowstand system tracts of sq5 and sq6 ( that is damoguaihe formation ) and deep water turbidite fans deposed in late trangrassive system tract and early highstand system tract are the major reservoir with good physical characteristics
层序5和层序6 (相当于大磨拐河组下段)低水位体系域沉积的低水位楔和低水位扇及水进晚期、高水位早期出现的深水浊积扇具有良好的储集物性，也是主要的储集层。 |
| 9. | In the interim from highstand systems tract to transgressive systems tract , faulting is violent in the basin , different kind of fluids coming from dissimilar position of lithosphere enter into synsedimentary faults served as a place fluids mixed to form ore - bearing hydrocarbon alkali - fluids
在从高水位体系域向海侵体系域的盆地相迅速转化时，盆地内断裂构造活动强烈，断裂沟通不同部位的热水流体，使成矿烃碱流体沿断裂上升，在海底沉积成矿。 |
| 10. | Directed by the advance theories of sequence stratigraphy , reservoir beds sedimentology , seismic stratigraphy and petro - geology , measured by exactitude seismic procession , analysis of seismic facies , analysis of single well lithfacies and sedimentary facies , study of macro and micro character of reservoir and diagenesis , this paper study comprehensively the stratigraphy sequence , the type and distributiong of sedimentary facies , reservoir properties , the diagenesis and the evolution of pores of the 2nd and 3rd parts of pingdiquan formation of permian in wucaiwan - shishugou region in jungan basin . we can optimum seek favourable target area and apply the study results on oil field production in order to solve the difficult questions . we mainly achieve several views as follows : l ) establish the sedimential sequence framework of permian formation in studying area and delimint the jiangjunmiao formation of middle dyas series as lowstand system tract , the lower of the second part to the third part of pingdiquan formation of middle dyas series as transgressive system tract , the upper of the second part to the first part of pingdiquan formation as highstand system tract
以层序地层学、储层沉积学、地震地层学、石油地质学的先进理论为指导，以地震资料精细目标处理、地震相分析、单井岩相分析、沉积相分析、宏观和微观储层特征分析及成岩作用研究为手段，对准噶尔盆地东部五彩湾? ?石树沟地区二叠系平地泉组二、三段的地层层序、沉积相类型及展布、储层物性特征、成岩作用及孔隙演化进行综合研究，优选出有利勘探区带，并将研究结果应用到生产中，解决生产中的难题，主要取得了以下几点认识：建立了工区内二叠系沉积层序框架，把中二叠统将军庙组地层划为低水位体系域，中二叠统平地泉组二段下部三段地层为水进体系域，二段上部一段地层为高水位体系域。 |
