Simulated experiment evidences of the corrosion and reform actions of H2S to carbonate reservoirs： an example of Feixianguan Formation, east Sichuan

The reservoir of Feixianguan Formation of the Lower Triassic in the Sichuan Basin is the deepest buried carbonate reservoir in China, with developed secondary corrosion holes, high quantities carbonate reservoir, maximum effective carbonate reservoir thickness. Also Feixianguan gas reservoir has the highest quantities of H2S. Research discovers that there are close relationships between the formation of reservoir and H2S. The mutual actions between acidity fluid and carbonate promoted the forming of secondary carbonate holes. Through the experiment of corrosion of the samples of Feixianguan carbonate reservoir in saturated aqueous solution of hydrogen sulfide, the porosity and permeability increased greatly, porosity increased 2% and permeability increased nearly two quantity degrees, also the density became light, which confirm the corrosion and reform actions of H2S to carbonate.     

Main controlling factors of distribution and genetics of marine reservoirs in China

Marine reservoirs are mainly made up of clastics and carbonate reservoirs, which are distributed widely in central Tarim, Sichuan, Ordos basins from the Pre-Cambrian to Cenozoic, mainly in Palaeozoic. Marine clastic reservoirs are developed in foreshore and nearshore, tidal flat and delta environment. The sedimentary facies are important controlling factors for reservoir quality. Compaction, pressolution and cementation are factors of decreasing porosity, and low palaeo-temperature gradient, early emplacement of oil and gas and dissolution are favorable for preservation of pore. Carbonate reservoirs are divided into reef and bank, karst, dolomite and fracture reservoirs. Dolomitization, dissolution, TSR and fracture are important factors of controlling carbonate reservoirs＇ quality.     

安徽南陵—铜陵地区茅口期碳酸盐孤立台地沉积特征分析

本文分析了安徽南陵-铜陵地区茅口期的沉积特征。描述和讨论的主要岩石类型有亮晶生物屑灰岩、泥晶海百合丘灰岩、含有机质藻粒泥晶灰岩、放射虫硅质岩及含钙质生物硅质岩。结合古生物和其它各种相标志,共划分出五个微相,即深水盆地、盆地边缘、碳酸盐缓坡、生屑浅滩和泻湖-潮坪相。研究区茅口期的沉积模式是一个被深水盆地包围的碳酸盐孤立台地。其地貌特征可与现代大巴哈马滩类比,所不同的是它发育了布满海百合灰泥丘的缓坡带。该孤立台地的沉积演化表现为向上变浅的海退序列。     

春风化雨 润物无声——专业教师班主任工作案例偶拾

2007年的9月,我怀着激动的心情做了电子0701班的班主任,近三年的班主任工作中,我经历了所有班主任都经历过的棘手问题,并在领导和同行的帮助下摸索出了一套自己的方法,现就以下三方面内容向大家汇报： （1）助学金发放;（2）大学生心理脆弱;（3）突发事件的处理。     

武广高速铁路风化花岗岩微观变化特征研究

结合工程实例,研究了风化过程中花岗岩的微观变化特征,采用光学显微镜、扫描电镜等测试手段,以风化剖面上的钻孔岩心为样本来源,揭示了花岗岩从弱风化演变为强风化过程中,微结构由粒状堆砌微结构演变为粒状架空微结构,粒间联结力由紧密演变为疏松,微裂隙由不发育演变为很发育,蚀变产物增多,粘土矿物大量增加,表明风化作用正是通过在改变了岩石的矿物成分、化学成分的基础上改变了岩石的微观结构特征,才最终改变了岩石的宏观力学性能.     

黔南下寒武统喳拉沟组黑色岩层风化特征

黑色岩层是一种广泛分布且具有特殊性质的岩石,探讨黑色岩层的风化特征,为黑色岩层边坡治理提供理论依据。选取黔南三都地区下寒武统喳拉沟组黑色岩层为研究对象,利用浸泡试验、水质分析试验模拟黑色岩层的水岩化学作用过程,通过黑色岩层风化中的矿物特征、化学成分特征来确定其风化阶段。研究结果表明:研究区黑色岩层在水岩作用中涉及多个复杂的化学过程,通过溶解、水解、水合作用逐步形成稳定的黏土矿物及次生矿物;黑色岩层的化学风化已完成去Na、Ca阶段,并初步进入中期的去K风化阶段。     

乐山大佛千年不朽之谜

四川凌云山的乐山大佛，大家都知道吧？它的身高足足有71米，那可是将近20层楼的高度啊。雕凿乐山大佛的石头，是一种很容易引起风化的红砂岩。可是一千多年过去了，乐山大佛为什么还好好地坐落在江边，而没有被大自然风化成一堆碎石块呢？它那跟山一样高大的佛像，当初又是怎样建造起来的呢？
