| 1. | Channel and point-bar sands may be clean and well-sorted . 河道砂和河曲沙坝砂可以是干净的和分选良好的。 |
| 2. | These may eventually coalesce to form an anastomosing system of channel sands within a broad valley . 最后它们在宽阔的河谷内连接起来,形成一个交织的河道砂系统。 |
| 3. | A case study is made for low sinuosity of distributary channel sandbody 对低弯度分流河道砂体开展了建模实例研究。 |
| 4. | A study of fine geological modeling of braid fluvial sandbody in the dense drilling zone 密井网区辫状河道砂体精细地质建模方法研究 |
| 5. | A typical case study on the sand body to subaqueous distribution river course and its oil enrichment 一个典型的水下分流河道砂体展布与油气富集规律 |
| 6. | The channel sandstones are as efficient reservoirs for its better reservoir quality , while the flood plain as the sealed beds 河道砂体因物性好而成为有效储层,而泛滥平原则成为封盖和遮挡层。 |
| 7. | Large scale salt - water intrusion has been occurred since late 1970 ' s due to freshwater exploitation by human activity 20世纪70年代末期以来,随着对地下淡水的过度开采,淡咸水水头压力差减小,卤水通过古河道砂层快速南侵。 |
| 8. | Major reservoir included sand bodies of subaquatic distributary channels in deltas , braided deltas , fan deltas , and sand bodies of turbidtte in deep lake 主要的储集层有:三角洲、辫状河三角洲、扇三角洲前缘水下分流河道砂体和深湖浊积岩砂体。 |
| 9. | 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。 |
| 10. | 5 . through the send granularity test of an ancient riverway in jinsha site , we obtain the ancient river is a snaking stream that can reflect a drouthy environment 通过对遗址中古河道砂的粒度分析,可以反映出当时的该古河流是一条反映较干旱环境的曲流河。 |
