The evolutionary model organic beach or reef reservoir, controlling factors of which are sedimentation, digenesis and tectonics ,are established according to the result of sedimentary facies and digenesis. At last regional distribution of reservoir has been predicted. Comprehensive study indicates the dark, 50-300 m thick upper Permian series, which is rich in the organic material and biota , is beneficial to formation and protection of petroleum and natural gas. Moreover the stratigraphy possess with better reservoir ability. The reservoir distributed in shallow glacis along Beichuan Tongkou - Guangyuan Changjianggou ,He 12 well - She 1 well - Jiange - Cangxi Yongningpu -Long 4 well - Bian 1 well in Wujiaping stage and in platform edge beach along Beichuan Tongkou - Jiangyou Shuigentou - Jiange -Cangxi Yongningpu - Nanjiang .

综合以上，本文认为研究区上二叠统地层厚50—300m，颜色较深、生物含量多、富含有机质，并且该套地层自形成后，大多直接进入埋藏成岩环境，是一套十分有利于油气的形成与保存的地层；同时该套地层的局部层段具有一定的储集性能，在吴家坪期储层主要分布在北川通口—广元长江沟、河12井—射1井—剑阁—苍溪永宁铺—龙4井—扁1井一带，在长兴期储层主要分布在北川通口—江油水根头—剑阁—苍溪永宁铺—南江一线。

Dolomitization is the important forming mechanism of buried hill reservoir.

白云石化作用是潜山内幕储层的重要形成机理，冶里一亮甲山组储集层与埋藏成岩过程的白云石化作用，尤其是与粒屑的优先白云石化造成的体积收缩作用有关。

The intraplatform point beach experienced good dolomitization and has good reservoir properties, with little development and thin thickness. Beach facies is only the basic condition for reservoir development.

由此可见，滩相沉积体仅是储层发育的基本条件，滩体最终能否形成有效的储集体，还要取决于后期成岩作用的改造。

The result shows that the oil-water contact is controlled by the structure,fault,sand distribution,petrophysical property and diagenetic epigenesist and is an irregular dip plane;reserves distribution is well related to the distribution of braided channel micro-facies in the.

结果表明：油水界面受构造、断裂、砂体展布、物性和成岩后生作用等多因素控制，为一不规则的倾斜面；储量分布与扇三角洲平原亚相的辫状水道微相分布具有较好的相关性；辫状水道微相是下一步扩边挖潜的有利目标。

The result shows that the oil-water contact is controlled by the structure, fault, sand distribution, petrophysical property and diagenetic epigenesist and is an irregular dip plane; reserves distribution is well related to the distribution of braided channel micro-facies in the fan delta plain; the braided channel micro-facies is a favorable target of extension in next step.

This process (mylonitization, migmatization and granitization) leads to mobilization and migration of gold.

深层次推覆构造带为一复杂的花岗质岩石的成岩带和金等有色矿产的成矿带。

According to the experimental results of Watson (1978), and Ryerson and Hess (1980), pertaining to the distribution of trace elements between basic and acidic liquids in the temperature above magmatic liquidus, and the investigation of Webster (1997) on the melt inclusion in pegmatitic quartz from Ehrenfriedersdorf ore district, Germany, it should be drawn that there probably exists the liquid immiscibility in the early stage of pegmatitic evolution, due to the perphosphorus content in the magmatic systems. The perphosphorus feature of the melt is of great impact on the petrogenesis and matellogenesis of pegmatites.

1997对德国Ehrenfriedersdorf矿区伟晶岩石英中熔体包裹体的研究成果，我们推断在富磷岩浆体系中，在其演化的早期将出现由磷引起的液相不混溶作用，它对伟晶岩成岩和Be的成矿具有重大的影响。

At the stage of platform, the "higher Pb-Zn source bed" would be formed in the plantform-type carbonatite forma tions, especially in the first carbonatite position after every large-scale ingression, by enrichment of weathering deposition, diagenesis, biogenesis and organogenesis.
