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。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
