These data are incompatible with the excursion scenario unless (1) carbonates deposited during a negative δ13C excursion are more susceptible to later δ18O metamorphic alteration in proportion to their negative δ13C value, or (2)δ18O of sea water decreases as δ13C of sea water decreases to produce an array that fortuitously resembles the Cenozoic lithification domain Fig.
这些数据与想象的同位素漂移情况不一致,有两个因素应当考虑在内。1。碳酸盐在δ13C存在负值漂移时沉积更加容易受到后期δ18O变质交代作用的影响,这种影响与δ13C成比例。2。海水δ18O与δ13C的同步减少使得数据出现在图表上的近似新生代成岩作用区域,这种情况属于偶然情况。

Diagenesis types include compaction,cementation, solution and metasomasis.
成岩作用类型主要包括压实作用、胶结作用、溶解作用和交代作用,其中胶结作用使储层原生孔隙迅速变差,而溶解作用是次生空隙发育的主要因素。

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。
