| 1. | The sequence develops a three - divided system tracts
层序发育三分体系域。 |
| 2. | Transgressive system tracts and related reservoir bodies of paleogene in western qaidam basin
柴达木盆地西部古近系湖侵体系域及相关储集体 |
| 3. | Yaojia formation and the member - one nenjiang group are lake expanding system tract of sequence 2
姚家组和嫩江组一段是层序2的湖泊扩张体系域。 |
| 4. | But , because the exploration exists larger dangerous in low stand system , it is not thought much
一般来说，低水位体系域砂体发育，是很好的储层。 |
| 5. | Water body is shallow and sediments are coarse in lst and hst , but in tst , being deep and fine
低水位体系域和高水位体系域水体较浅，沉积较粗，而湖进水位域则水体较深，沉积较细。 |
| 6. | 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。 |
| 7. | It is condensed section with shells , downlap surface and ravinement surface that constitute the critical boundaries in dividing the system tracts of matuo formation
含有介壳的凝缩段、下超面及沟蚀面是划分玛托组体系域的关键界面。 |
| 8. | Hence , tracing this boundary and searching for the delta distributary channel sands in lst and tst will be the key for petroleum exploration in this area
厘定追踪该界面并寻找该界面之上的低水位体系域和水进体系域的三角洲分流河道砂体是勘探的关键。 |
| 9. | 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。 |
| 10. | The sequence architecture and the distribution of depositional systems tracts were mainly controlled by a variety of tectonic activities during the formation and evolution of the basins
层序构成和沉积体系域的发育分布受到盆地形成演化过程中各种构造作用的控制。 |
