盆地东部地区盐下油气藏规模、储量较大，大中型油气藏主要与石炭系两套海相碳酸盐岩层（KTⅠ和KTⅡ）有关。

The large - and / or moderate-sized reservoirs are mostly relative with the both beds of Carboniferous marine carbonate rock , the target horizons , KT - ⅰ and KT - ⅱ .

河南铝土矿为上古生界石炭系本溪组的G层铝土矿，分布在三门峡郑州平顶山这个三角地带。

Henan bauxite , which belongs to G layer bauxite of Benxi Formation , Carboniferous , Upper Paleozoic , developed in Sanmenxia Zhengzhou Pingdingshan triangle belt .

新生界松散岩类孔隙含水层系统和石炭系-侏罗系碎屑岩类裂隙含水层系统的交替循环深度较小（一般小于300m）。

The Cenozoic groundwater system and the clastic fissure groundwater system in Carboniferous and Jurassic have shallow circulation depth ( less than 300m ) .

鄂尔多斯盆地石炭系厚0～600m，属潮坪三角洲相。

The Carboniferous strata , is up to 0 ~ 600 m thick in Ordos basin , are ascribed to the tidal-delta sediments .

石炭系产层经济极限条件是渗透率大于0.5×10-3μm2或导压系数大于0.01m2/s。

And the economically-limiting conditions of forming productive formation in the Carboniferous in East Sichuan are that the permeability must be larger than 0.5 × 10 - 3 μ m 2 or the pressure transmitting coefficient 0.01 m 2 / s.

从地质和工程方面分析了塔河油田S100井三叠系、石炭系地层钻井过程中井眼易失稳的原因，给出了其钻井液及工程技术措施。

This paper analyzes causes of sloughing during drilling through Triassic and Carboniferous systems of well S100 in Tahe Oilfield proceed from geology and engineering aspects and presents the corresponding muds and engineering measures .

根据工作面附近的地质构造推断，突水通道为延伸到奥陶系与石炭系不整合面的铲状滑动断层（该断层最大落差只有7m左右）。

According to the structural characteristics , it is concluded that a spade shape fault , which extends the unconformity boundary between Ordovician and Carboniferous , and whose maximum fault throw is 7 m , is responsible the accident .

该油田的主要油层为石炭系，深度为2800～3800m左右。

The reservoir of this oilfield is mainly in the Carboniferous system , and its depth is between 2800 - 3800 m.

石炭系储集条件良好，孔隙度为5.01%～7.78%，平均渗透率为2.5×10－3μm2，有效储层厚度14.7～30.35m，分布较稳定，储层类型为裂缝&孔隙型；

The storage condition is good , porosities being 5.01 % ~ 7.78 % , average permeability 2.5 × 10 - 3 μ m 2 and effective reservoir thicknesses 14.7 ~ 30.35 m ; the distribution of the reservior bed is stable and it belongs to the porous fractured one ;

根据宽带约束反演及岩性约束反演得到地震资料约束反演（DCI）剖面，由DCI剖面求出岩石密度衰减系数及其与石炭系厚度的乘积（储层CDT值）。

Restrictive inversion and lithology restrictive inversion may be used to produce seismic data controlled inversion section , from which rock density attenuation coefficient and reservoir CDT ( product of the coefficient and the thickness of Carboniferous system ) are derived easily .

塔里木哈德地区石炭系地层深度为5005-5015m，两个油层厚度均为1-2m，属低压、低渗透油气藏。

Reservoirs in the carboniferous system of 5005-5015 m in Hade area of Tarim are low pressured and low permeable , with oil bearing thickness of 1-2 m.

由于该区石炭系目的层埋深大（超过3500m），特别是上覆二叠系巨厚盐丘造成速度横向、纵向剧烈变化，从而导致石炭系构造畸变。

Since the deep depth of Carboniferous targets in the region ( deeper than 3500m ), especially the rapidly changed velocity in both lateral and vertical direction resulted from significant thickness of overlying Permian salt dome leads to imaging distortion of Carboniferous structures .

通过典型样品的氢同位素、δ13C2和轻烃异庚烷值指标关系分析，说明腐泥型气只能来自奥陶系，不可能来自石炭系。

Based on argon isotope and the relation of iso-heptane value with δ 13C2 , the sapropelic gas in mixed gas of the central gas field can but come from Ordovician , not Carboniferous .

构造沉积背景分析表明，塔里木盆地北部石炭系含盐层系主要形成于干旱炎热气候条件，受海平面变化控制的滨岸潮间蒸发泻湖环境，厚度为80～221m。

On the analysis of tectonic depositional setting , the Carboniferous salt bearing set in North Tarim Basin mainly formed in the hot and dry evaporating lagoon environment of beach intertidal zone controlled by sea level changes with the thickness of 80 ~ 221 m.
