| 2. | Locally dolomite and anhydrite are important as cements, together with minor authigenic quartz . 在局部地方白云石和硬石膏也是重要的胶结物;还有少量自生石英。 |
| 3. | There are five stages of cements in qianmiqiao buried hill carbonate strata 通过千米桥地区的研究,认为其胶结物世代存在五期。 |
| 4. | They changed the porosity characteristics of sandstone , engendering new benefit storing beds consisted with secondary porosity 浊沸石矿物是长6砂岩中普遍的胶结物,它的形成与火山物质水化有关。 |
| 5. | Chemical compaction and cementation are the other two important factors caused the loss of porosity . the main cements include carbonate and quartz overgrowth 在胶结物中,碳酸盐和次生石英胶结物是影响储层物性变差的主要胶结物。 |
| 6. | The evidence that the fluid comes from the down earth ' s crust and mantle did not found by studying fluids ( water , glued thing and natural gas ) in the basin 川西前陆盆地流体(水、胶结物和天然气)的研究,未发现来自下地壳及地幔的深部流体地球化学证据。 |
| 7. | The process of diagenesis controlled partly by sedimentation , the evolution of pores influenced by it . the affection of origin ingredient and structure in sand to sediment and solution in gooey be exhibited 长6储层砂体中沉积作用对于成岩进程的控制,主要表现在砂岩的原始成分和结构对于胶结物的沉淀和溶蚀的影响。 |
| 8. | The activity area of sediment and solution in gooey is distributary river , which has gigantic water power , good degree of sorting and roundness , gruff grain . lower mud and mica content 分流河道的主体部位水动力较强,分选性和磨圆度较好,粒度粗,云母矿物和泥质含量较低,是胶结物沉淀和溶解的活跃区,因而也是物性相对较好的地方。 |
| 9. | This kind of adglutinate mixed with u expansion admixture can grip anchor bolts tightly even underwater , as can be seen from the pull - out type tests for anchor bolts when the mortar age is over 10 days . ( 2 ) the author lays the supporting piles as a arched shape 将掺加了u型微膨胀剂的砂将作为锚杆水下胶结物,由锚杆龄期10天的抗拔试验结果可以看出,这种胶结物的握裹效果很好。 |
| 10. | Researches of more than four decades in the field , especially from the early 1980s on , during which the analysis of the isotopes in fossil brachiopods and early diagenetic cements has contributed much to the knowledge , achieved appreciable progress 40多年的研究结果,尤其是进入80年代方解石质的腕足化石壳体和早期成岩胶结物等特殊样品的应用,取得了若干重大研究进展,但同时也发现了一些新的问题。 |
