| 1. | The reservoir sandstone was believed to have been deposited in a littoral environment .
储集层砂岩就被认为是近海环境的沉积。 |
| 2. | Reservoir sandstone diagenesis of memeber 6 to 8 in yanchang formation triassic , xifeng oilfield , ordos basin
8段储层砂岩成岩作用研究 |
| 3. | Authigenic minerals and their occurrence in the meso - cainozoic reservoir sandstones were observed and analyzed by optical microscope , sem , epma and xrd
采用光学显微镜、扫描电镜、电子探针及x射线衍射观察分析了塔里木盆地中新生界储层砂岩自生矿物及其在岩石中的产状。 |
| 4. | In the second part , permeability of reservoir sandstones was investigated by using fractal theory , which is one of powerful tools for dealing with complicated , anomalous phenomena and processes
第二部分，主要利用研究复杂的、不规则现象和过程的强有力工具分形理论，对储层渗透率加以研究。 |
| 5. | There are two types of fluid inclusions : petroleum inclusions and aqueous inclusions in the reservoir sandstones . the homogenization temperatures of the aqueous inclusions associated with petroleum inclusions range from 107 to 141
与石油包裹体共生盐水包裹体均一温度107 - 141 ，结合受热史推断出成藏时间在2 . 5my以后。 |
| 6. | The feldspar of the reservoir sandstone in the study area consists of a higher percentage of na feldspar that of k . feldspar . the sandstone is composed of certain little rock fragments such as pyrite , mica , siltstone , mudstone , chert , and volcanic fragments
砂岩内长石由钠长石与钾长石组成，以钠长石为主；岩屑由黄铁矿、云母、粉砂质、泥质、燧石与火山岩屑构成。 |
