Carbonate rocks are predominantly composed of intra - clastic dolostone , chert dolostone and sand - bearing dolostone 碳酸盐岩以内碎屑白云岩、燧石白云儿和含砂白云岩为主。
2 ) the contraction action of granulations can form the pore of dolostone reservoir in the course of dolomitization 2 )在白云石化过程中岩石粒屑的收缩作用可以形成白云岩储层孔隙。
This distinct difference can benefit the organizations of specialized , big - sized and commercialized productions 尤其是石灰岩、白云岩找矿前景好，且远景规模大，质量好，宜露天开采。
The feixianguan formation of evaporative carbonate platform is a set of sulfate - bearing evaporative tidal sediments with aboundant dolomite 飞仙关组蒸发台地为一套含硫酸盐的富白云岩的蒸发潮坪沉积层系。
The feixianguan gas reservoirs in the luojiazhai gas field , northeastern sichuan province , are composed of the porous oolitic dolomites 摘要四川东北部罗家寨气田的储层为下三垒统飞仙关组孔隙性鲕粒白云岩。
Technique for prediction of dolomite fractured reservoir has been quite urgent for petroleum exploration and development in biyang sag 摘要白云岩裂缝型储集层预测技术是目前在勘探开发中迫切需要解决的问题。
Selecting natural dolomite as raw materials , the authors made a new kind of pearl nuclei through mechanic grinding and surface treatment 摘要筛选天然白云岩为原料，采用机械磨削和表面处理等工艺，制成新型珠核。
According to the mechanism of dolomitization , it can be divided into penecontemporaneous dolostone and post - penecontemporaneous dolostone 白云岩可据白云石化作用的机理和时间分为准同生白云岩和准同生后白云岩两大类。
It used to be considered that the loushanguan formation was composed of thick - bedded dolomite , which is very difficult for division 传统上认为湘黔交界处的中寒武统?下奥陶统娄山关组为均一性极强的厚层白云岩，可分性极差。
According to whether remnant grains exist , post - penecontemporaneous dolostone can be divided into remnant grain dolostone and crystalline dolostone 准同生后白云岩根据残馀颗粒的有无可分为残馀颗粒白云岩和晶粒白云岩两大类。
