The surface of the fragment developed a botryoidal or oolitic form.

铁碎片的表面呈现葡萄状或者鲕粒状。

The authors summarize the dolomization genetic model of oolitic beach reservoir.

海平面频繁的变化是发生混合水白云石化作用的主要动力。

Mixed water dolomization is the basis of platform fringing oolitic beach reservoir of Feixianguan group.

残余鲕粒白云岩是飞仙关组鲕滩气藏最有利的储层。白云石化作用是有效储层形成的关键因素之一。

Original porosity is typified by the intergranular porosity of sandstones and the intercrystalline and oolitic porosity of some limestones.

原生孔隙度以砂岩粒间孔隙度和某些石灰石的晶体粒间和鲕状孔隙度为代表。

其中具有储集意义的仅为多期次埋藏交代成因的成岩白云岩，包括鲕粒白云岩和晶粒白云岩两种主要结构类型。

Due to a series of large or oversize scale oolitic gas pools were found in Feixianguan Formation in NE Sichuan Basin, the gas exploration have a good prospect. The questions about origin and accumulation of the natural gas in oolitic reservoir have been one of the focus in the field of petroleum geology.

四川盆地东北部飞仙关组一系列大型、特大型鲕滩气藏的发现，显示出该区巨大的勘探潜力和良好的勘探前景，有关鲕滩天然气的成因、来源及成藏等问题，是当前油气地质学研究的热点之一。

The beach body of Lower Triassic Feixianguan Formation in northwestern Sichuan can be divided into platform marginal oolitic beach and intraplatform point beach. The water is relatively deeper at the forming of most of platform marginal oolitic beach which is not transformed by the diagenesis of fresh water and mixed water and has poor reservoir properties. However, a part of oolitic beach formed under shallow water environment, and it is transformed by the diagenesis of fresh water and mixed water and well dolomitized, which can form excellent reservoir.

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。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.
