1) oolitic beach
鲕粒滩
1.
The beach body of Lower Triassic Feixianguan Formation in northwestern Sichuan can be divided into platform marginal oolitic beach and intraplatform point beach.
川西北下三叠统飞仙关组滩体分为台地边缘鲕粒滩和台地内点滩2种类型,多数台地边缘鲕粒滩形成时水体相对较深,未经大气淡水和混合水的成岩改造,储集性能较差,局部鲕粒滩形成时水体较浅,在经过大气淡水和混合水的成岩作用改造后,白云石化好,可形成储集性能极好的储集体;台地内点滩白云石化较好,储集性能也较好,但分布狭窄,厚度较薄,无规律可寻。
2.
It is thought that: the reefs are transgressive reefs formed during the regional sea-level rise and vertically mainly distributed in the middle and upper parts of the Changxing Formation, and the oolitic beaches mare mainly regression beaches developed in the process of regional sea-level fall and ver.
本文对四川盆地北部长兴组礁和飞仙关组滩特征和分布及其控制因素作了较为深入的探讨,研究认为生物礁为海平面上升过程中形成的海侵礁,其在纵向上的分布主要位于长兴期中晚期;鲕粒滩主要是在区域海平面下降过程中形成的海退滩,其在纵向上位于飞一—飞三。
2) oolitic bank
鲕粒滩
1.
Diagenesis of oolitic bank of the Feixianguan Formation of Lower Triassic in Luojiazhai Gas Field,northeastern Sichuan Province;
川东北罗家寨气田下三叠统飞仙关组鲕粒滩成岩作用
2.
On the basis of the sedimentary characteristics and reservoir distribution law in Feixianguan Formation of Upper Permian-Lower Triassic,East Sichuan Basin, it can be determined that the characteristics and distribution of Changxin reefs and Feixiangguan oolitic banks are tighly relevent to the fluctuation of sea-level.
据四川盆地东部上二叠统—下三叠统飞仙关组沉积特征和储层分布规律 ,认为区内长兴组生物礁和飞仙关组鲕粒滩特征和分布与海平面升降有关。
3) oolitic beach
鲕粒滩坝
4) oolitic shoal
鲕粒浅滩
5) oolitic bank reservoirs
鲕粒滩体
1.
The research of seismic attribute shows that the oolitic bank reservoir in Feixiangan Formation has the characteristics of high amplitude,high frequency attenuation and abnormal phases,and the oolitic bank reservoirs mainly distributed in the eastern area of D4-h16-h19 wells.
在沉积与储层基本特征研究的基础上,利用多种地震预测方法对川东北黄龙场气田下三叠统飞仙关组鲕滩储层的分布进行了预测:利用地震剖面层拉平方法,恢复了黄龙场气田飞仙关期东高西低的沉积古地貌,自东向西依次发育台地边缘、台缘斜坡及陆棚相带;根据地震响应特征,识别出4种不同的地震相类型,并且利用神经网络波形聚类技术,指出了不同地震相的平面分布;通过均方根振幅、波形及弧长等地震属性的提取与处理,发现飞仙关组鲕滩储层具有强振幅、高频衰减、强相位异常等特征,揭示了鲕滩储层主要分布于东部的D4井—hl6井—hl9井一带;应用井约束稀疏脉冲反演方法,指出飞仙关组鲕滩储层低速异常明显,主要分布在距飞四底反射层0~60ms范围内;利用三维地震数据体追踪点集,雕刻了飞仙关组鲕粒滩体的三维空间分布特征。
6) Oolitic shoal
鲕滩
1.
Diagenesis and pore evolution of the oolitic shoal reservoir in the Feixianguan Formation in northeastern Sichuan;
川东北飞仙关组鲕滩储层成岩作用和孔隙演化
