Examples
- According to synthesize evaluate , the distributary channel sandbodies and river mouth bars are best reservoir
通过综合评价认为，水下分流河道和河口砂坝微相为本区最好的储集层。 - The delta front mainly developed in chang 6 , which includes microfacies , such as distributary channel sandbodies , river mouth bars , distal bars and so on
长6期是三角洲建设的高峰期，发育三角洲水下分流河道与河口砂坝砂体及远砂坝微相。 - According to analysis of sedimentology , we think the most benefit environment to reservoir is under - water branch and river mouth bars microfacies , which often form thick sand bodies of high porosity of permeability
从沉积相分析认为，有利于储层发育的沉积环境是水下分流河道和河口砂坝微相，水下分流河道控制了砂体的走向及分布区。 - According to observing the core and well logging facies analysis , yanchang 4 + 5 sector to yangchang 3 mainly developed underwater distributary channel , river mouth bars , underwater natural levee , underwater crevasse splay , interdistributary bay , far bars , etc . and some shallow lake subfacies
根据岩芯观察以及测井相分析，认为长4 + 5 ?长3期以水下分流河道、河口砂坝、水下天然堤、水下决口扇、分流间湾和远砂坝等沉积微相以及部分浅湖亚相沉积为主。 - Yanchang 4 + 5 sector to yanchang 3 sector lithofacies palaeogeography pattern was stable , because the constitution background was steady , and the source direction had no change , and supply was abundant . in those sectors the basin development was in lake retreat , and in the period of extinction gradually , and formatted construction delta deposit , but in yanchang 33 period the sedimentary speed were greater than construction speed , showing that overriding river mouth bars were abundant
长4 + 5 ?长3期湖盆发展处于湖退、萎缩逐渐消亡时期，由于构造背景稳定，物源来源方向没有变化，物源供给充分，所以岩相古地理格局基本一致，形成建设性三角洲沉积，但长3 ~ 3期沉积速率大于构造沉降速率，表现为叠置河口砂坝极其发育。
