您要查找的是不是:
- coaly mudstone 煤系泥岩
- Sequence V is Miocene swamp variegated silt, mudstone interbedded by coaly shale and coal seam. The Oligocene middle grain silt probably deposited in the bottom. 层序V,为中新统沼泽相的杂色砂泥岩夹炭质页岩、煤层,往下可能还含有少量渐新统中细砂岩。

- The cover rocks are marine mudstone from Pliocene to Quaternary. 储层发育有砂岩、灰岩(礁灰岩)、基岩等。
- Sha 4 submember Kongdian Formation mudston is regional cap rock. 区域盖层为馆陶组、沙河街组四段及孔店组的泥岩层。
- Cretaceous sandstone and Eogene mudstone are the main reservoir and caprock. 油气从油气田东部注入 ,由东向西运移并差异聚集 ,依次形成凝析气藏、带油环凝析气藏和挥发性油藏。
- The reservoir is usually lamina sandstone interbbeded with mudstone. 储层砂岩与泥岩大多呈薄互层状。
- The main rocks are sandstone, mudstone and muddy siltstone or silty mudstone. 岩石类型主要有砂岩、泥岩及泥-粉砂过渡岩类。
- The dark mudstone deposited in this time is the favorable source rock. 同时,该层序内沉积的暗色泥岩也是有利的烃源岩。
- The coal and coaly organic matter are believed mainly to be hydrocarbon souce of the basin in the middlelow Jurassic of the Turpan-Hami basin. 吐哈盆地中下佛罗统煤及煤系有机质被确认为该盆地的主力烃源岩。
- Eocene through lower Oligocene lacustrine shales and Oligocene through lower Miocene lacustrine and deltaic coaly shales are the mature source rocks. 始新世到渐新世湖泊页岩、渐新世到中新世到湖泊和三角洲页岩都是成熟的矿源岩。
- The coaly muddy water is difficult to use,the main reason is the small grainy coaly mucl is amassed in the coaly muddy water for a long time. 细粒煤泥在煤泥水中的长期积聚是影响煤泥水处理效果的主要原因。
- The sediments are mudstone, shale, carbonaceous mudstone and marl of deep and semi-deep lake facies. 烃源岩已进入成熟阶段,处于生油高峰期。
- According to the analysis to the coaly facies,the coal lithotypes,the coal rock composition,the text discusses the influence factor of coal endogenic crack. 文中通过对煤相、煤岩类型、煤岩成分的分析,论述了煤中内生裂隙的影响因素。

- The Upper Shihezi formation with a vast thick mudstone layer can be taken as a very good seal, so it is difficult for natural gas to pass through. 近年来,相继在盆地东部的石千峰组地层中发现了一系列次生气藏,其形成机理逐步引起了勘探家的关注。
- Gases from Triassic coaly source rock accumulated during Laramide and original gas pool formed.During Himalaya, thrusting movement promoted the shallow reservoir storage ability. 来自上三叠统煤系源岩的天然气聚集主要在燕山期,形成原生气藏或下生上储型气藏;
- It passes mainly through the purple--color soft sandrock and mudstone in Triassic or Dyas Systems. 隧道主要通过三迭系、二迭系紫红色软质砂岩、泥岩岩层。
- Results show that the main factors influencing methane desorption include pressure,gas content,coaly moisture content,matrices size and temperature etc. 结果表明:影响解吸的因素主要是压力、含气量、煤的水分含量、基块尺寸、温度等;
- The seal rocks are developed widely,and the Neocene marine mudstone is the regional seal. 盖层发育广泛,区域性盖层是新近系海相泥岩和渐新统泥岩。
