地质录井岩屑描述英文

Lithology description

Description cutting by microscope显微镜下描述岩性, check color颜色, grain size粒度, roundness圆度, hardness硬度, texture结构，Structure构造, porosity孔隙度, cement胶结, content 含有物，mode of occurrence产状。

1.Color颜色:example例如: gray灰色，light gray浅灰色，dark gray深灰色，greenish gray绿灰色，olive greenish gray橄榄绿灰色，brownish gray褐灰色, green绿色, brown褐色, black黑色,red红色, white白色, off white无色, mottled 杂色的，etc等等.

2. Litho logy name 岩性定名：

clay stone 泥岩，siltstone 泥质粉砂岩，very fine sandstone粉砂岩，fine sandstone 细砂岩, medium sandstone 中砂岩，coarse sandstone 粗砂岩，very coarse sandstone 砂砾岩，granule 细砾岩，小砾岩，pebble 鹅卵石（中砾岩），couble大砾岩，boulder 巨砾岩。Coal 煤, lignite 褐煤，limestone 灰岩，mudstone 泥灰岩，packstone 泥粒灰岩，iolite 鲕粒灰岩，wackstone 灰泥石灰岩，grainstone 颗粒石灰岩，boundstone 粘结岩，crystalline carbonate 结晶碳酸岩，dolomite 白云岩，basalt 玄武岩，tuff 凝灰岩，magna 岩浆岩，metamorphic rock, 变质岩，gypsum 石膏，anhydrite 硬石膏，igneous rock 火成岩，chart 燧石，quartzite 石英岩，

Check grains by microscope with grains chart,显微镜下观察粒度并与粒度板对比确定岩屑粒度。Grain size as follow （FIG1）粒度见下及图1:

3．Roundness

very angular , angular 棱角状，sub angular 次棱角状，sub rounded 次圆状，rounded 圆状，well rounded，as show in FIG 1见图1

4 sorting:

very well sorted 分选极好的，well sorted 分选好，moderately sorted分选中等，poorly sorted 分选差。

5．hardness determine hardness by needle 用钢针来判断，岩石硬度：

very soft 极软，soft 软, firm较软, moderately hard 较硬, hard硬, very hard 极硬.

6. cement胶结and cement 胶结物:

clay 粘土, argillaceous泥质，kaolinite 高岭土（高岭石），chalk白垩土，glauconite

海绿石，calcareous灰质, siliceous 硅质的。

Unconsolidated 疏松，very poorly 极差，poorly差，moderately 中等，well 好，very well 极好。

7. calcareous bearing 含钙情况:

put cutting onto porcelain and drop ten percent hydrochloric acid on it and check the reaction 把岩屑放到磁盘上,滴10% 的盐酸，观察反应情况。non calcareous不含钙, slight calcareous微含钙, calcareous 含钙。

8. The way to distinguish cement and cutting ,区别水泥和岩屑的方法：

Put cutting onto porcelain and drop liquid of phenolphthalein on it , if the color turn into red , that means there is cement in the cutting

把岩屑放到磁盘上，滴酚酞溶液，如果颜色变红，说明岩屑里有水泥。

9. porosity 孔隙度：

very poor 极差，poor差，fair 中等，good 好，very good 极好。

10. direct fluorescence and cut fluorescence 荧光直照和系列对比：

Put cutting onto porcelain, and drop some chloroform (chlorothene) on it , then put porcelain under fluorescent lamp check 把岩屑放到瓷盘上滴上氯仿，然后放到荧光灯下观察。

11. oil bearing description含油描述:

color颜色, odor气味, stain浸染痕迹, percentage of cutting含量,

direct fluorescence and crushed cut fluorescence , nil无(no show), trace少量, poor 差, fair中等, good好,very good 很好。

12. content 含有物：

argillaceous含泥, sandy含砂, salty含粉砂, carbonaceous speck含炭屑,calcareous 含钙, shell含贝壳, igneous fragment火成岩碎块（岩屑）, glauconite海绿石, kaolinite高岭石, chalk白垩土, pyrite黄铁矿, algae海藻, ammonite菊石。Mica云母

14. Structure 构造：

foraminifer 虫孔，karts 喀斯特，microfra裂隙，conchoid
