砒砂岩筑坝施工方法初步试验研究
|
| 3. | The reservoir from the lower part of qiketai formation to xishanyao formation is mainly composed of feldspathic litharenite , which is the second lithologic section
七克台组下部-西山窑组储集层以长石岩屑砂岩为主，属于第二岩性段。
|
| 4. | The petrographic and xrd analysis reveals that the reservoir of the upper part of kongdian formation mainly consists of feldspathic and minor amount of lithic sandstone . the feldspar is consisting mainly of na
岩石学与xrd全岩分析表明，孔店组上段砂岩主要为长石砂岩，此外还发育少量岩屑砂岩。

| 5. | The feldspathic sandstones belong to this formation of composite sources metamorphic , sedimentary , and igneous sources , but mainly from metamorphic source due to the high abundance of brown cl colors of quartz
上述情况表明，研究区长石砂岩物源母岩包括变质岩、沉积岩与火成岩，但从发育大量棕色石英颗粒来看，物源以变质岩为主。
|
| 6. | According to rock and mineral analysis , the formation consists dominantly of detrital feldspathic fine - sandstone with medium and silt sandstone secondly . lithologically , the content quartz is lower than those of feldspar and detritus , and the cement is dominated by clay , which gives the feature of low compositional maturity and low textural maturity
馆上段储层岩性以岩屑质长石细砂岩为主，其次为中细砂岩和粉砂岩，岩石中石英含量低，而长石、岩屑含量高，胶结物以泥质为主，表现出低成分成熟度和低结构成熟度的特点。
