- We suggest that the favorable reservoir facies within Ganchaigou Formation in West Qaidam Basin are delta front facies, fan-delta front facies, dam-and-beach facies of the littoral and shallow lake, lacustrine floor fan facies and carbonates facies. 强调了三角洲相前缘、扇三角洲相前缘、滨浅湖滩坝、湖底扇以及碳酸盐岩沉积是西部地区干柴沟组有利的储集岩相带。
- The fan delta front sheet sand and the slump turbidite system that arecontrolled by the cascade fault landform of the actic region is the advantageous areaof seeking a section of lithologic trap of the Dongyi interval. 陡坡带断阶地貌控制下的扇三角洲前缘砂体及滑塌浊积体是寻找东一段岩性圈闭的有利地区;
- The favorable reservoirs are mainly involved with lowstand fan，lowstand wedge，highstand delta front，highstand fan delta front and the turbidity fan in these two secondorder sequences. 这2个二级层序内的低位扇、低位楔，高位三角洲前 缘、扇三角洲前缘沉积以及湖底浊积扇体系是形成油气藏的有利部位。
- The exploration practice indicates that this area developed delta front slump turbidite fan and deep-water turbidite fan, as well as transportation systemand favorable mudstone seal. 勘探证实，东营凹陷东部发育三角洲前缘滑塌浊积、深水浊积扇等砂体类型，同时发育断裂型、砂体型、不整合面型等多种输导体系和良好的泥岩盖层。
- Main reservoir bodies include the river sandbodies of sublacustrine fan and the subaqueous distributary channel sandbodies in the delta front as well as sandstone dam in coast and shallow lake. 储层砂体主要为湖底扇河道、三角洲前缘水下河道及滨浅湖砂坝沉积。
- They are widely developed in delta front, and they usually overlap vertically and occur in belts regionally. 它们在三角洲前方广泛发育，垂向上相互叠置、平面上成带出现。
- Seismicity can damage the stability of delta front and form liquefied fluxoturbidite and faulted fluxoturbidite. 其中地震作用可以破坏三角洲前缘的稳定性，形成液化滑塌浊积体和断阶滑塌浊积体。
- It has a two-layer structure, i. e. braid-river delta plain subfacies and braid-river delta front subfacies. 它明显分为两层，即辫状河三角洲平原亚相和辫状河三角洲前缘亚相。
- During the abandonment period of delta, sediments of delta front were usually rebuilt by tidal action. 在三角洲废弃期，三角洲前缘沉积物常被潮汐作用改造。
- In contrast , the regular and good reserved delta front is disadvantaged to form fluxoturbidite. 相反,形态规则、保存完好的三角洲前缘反而不利于滑塌浊积岩的形成。
- The sedimentary facies is the underwater distributary channel of delta front with good accumulation ability. 针对该地区探井少、地震资料品质较差等特点，开展了储层综合预测技术应用研究。
- The reservoirs in the study area are mainly delta plain distributary channel sand body and delta front underwater distributary channel sand body. 研究区储层主要为三角洲平原分流河道及三角洲前缘水下分流河道砂体；
- The braided nyc delta front subfacies located on the south slop area is developed in the braided rive delta which progrades from south to north. 利用沉积体制方法研究丁沾化凹陷孤南洼陷沙三段中亚段中部沉积体系平面分布规律。
