| 摘 要： | 论述了吐鲁番－哈密盆地辫状河三角洲的沉积特征及孔隙类型。认为辫状河三角洲是辫状河进积到滨浅湖而成的粗粒三角洲，其水上部分为辫状平原，主要由辫状河道组成，水下部分主要为水下分流河道，二者呈三层叠置，其骨架主要为河道砂体；辫状河三角洲由于其储集体分选较好，粒度较粗，泥质含量较低，各个岩相侧向连续性较好而具有极大的油气储集潜力，是今后油气勘探不可忽视的相带。

| Abstract: | Braid deltas are coarse-grained deltas formed by progradation of braid rivers into shoreshallow lakes.Their above water portion is braid plain mainly composed of braided channel and theirsubmarged part is mainly underwater distributary channel,overlying each other.Their skeletons aremainly channel sand bodies.Braid deltas, owing to their better sortinq, coarse qrain and lower mudcontent in the reservoir and the better lateral continuity of various rock phases,have great potential ofoil and gas contents and are can not be neglectaed further exploration of oil and gas. |
