查询词典 dawsonite

In Surennuoer faulted zone, the authigenic mineral assemblage of dawsonite and ankerite are formed during the mutual action between CO2 fluids and sandstone, and then the reservoir properties of dawsonite-bearing sandstone becomes poorer.

苏仁诺尔断裂带CO2流体在与砂岩相互作用过程中，形成了片钠铝石和铁白石的自生矿物组合，导致研究区含片钠铭石砂岩储层物性变差。

Based on the study on the reformation of Dawsonite sandstones with CO2 fluids at different temperature (100℃, 200℃ and 300℃) and different the CO2/H2O/sandstone systems in inclosed containers, it is suggested that the corrosion intensity of dawsonite sandstone will gradually be enhanced as the temperature increases.

不同温度（100℃，200℃和300℃）下CO2流体对含片钠铝石砂岩的改造作用研究显示：随着温度的升高，砂岩的溶蚀、溶解程度逐渐增强，样品中片钠铝石的稳定性逐渐减弱。

The solubility experiment for dawsonite indicated that under the stratigraphic condition, the temperature for the solution of dawsonite in 100~150℃,and the generation of some carbonate and other new mineral can occur after the reaction.

片钠铝石的溶解实验表明，地层条件下片钠铝石发生溶解的温度区间为100~150℃，且反应后有碳酸盐及其他矿物生成。

The solubility experiment for dawsonite indicated that under the stratigraphic condition, the temperature for the solution of dawsonite in 100-150℃,and the generation of some carbonate and other new mineral can occur after the reaction.

片钠铝石的溶解实验表明，地层条件下片钠铝石溶解的温度区间为100-150℃，且反应后有一些碳酸盐矿物和其他新矿物生成。

Based on the analysis of the mutual action between CO2 fluids and sandstone, it is found that the higher content of dawsonite is the main cause for poorer reservoir properties, and the dawsonite is formed later than other authigenic minerals and no erosion occurres after the pores filling, which are the basic factors resulting in poor reservoir properties.

分析CO2流体与砂岩的相互作用发现，片钠铝石含量较高是储层物性变差的直接原因，而片钠铝石生长时间晚于其它自生矿物且在充填孔隙后没有发生溶蚀是储层物性变差的根本原因。

Abundant instances and experimentations on synthetic dawsonite indicate that carbonic acid or excess carbon dioxide is necessary for generating dawsonite. Therefore, occurrence of dawsonite is always associated with carbon dioxide gas reservoir.

大量的实例及人工合成片钠铝石实验表明，片钠铝石的形成需要碳酸溶液或过量的CO2气，片钠铝石的分布往往与CO2天然气藏相伴生。

At the same time, the SEM study shows that gibbsite occurs on the sample surface. At 200 ℃, as dawsonite sandstone is being dissolved authigenic siderite forms. At 300℃, chlorite deposit on parts of the sample surface. The weak solution of dawsonite sandstone at 100℃ and the formation of siderite at 200℃ illuminate that CO2 being in carbonates in the strata can not be released when CO2 phase is adding to the system.

同时，各温度下样品表面均有一水软铝石放射状集合体沉淀。200℃时，随着片钠铝石的溶解有自生菱铁矿生成，300℃时样品局部有绿泥石沉淀。100℃下片钠铝石的微弱溶解及200℃下菱铁矿的形成表明，在地层条件下以碳酸盐矿物形式捕获的CO2，不会由于CO2的二次注入而重新释放。

The morphology, occurrence and components of dawsonite were described, and the paragenetic sequence of sandstone and origin of CO2 forming dawsonite were investigated by polarization microscope, scanning electron microscope, Xray diffraction and MAT251 stable isotope mass spectrometer.

利用偏光显微镜、扫描电镜、X射线衍射分析仪和MAT251稳定同位素质谱仪，详细描述了片钠铝石的形貌、产状和成分，确定了含片钠铝石砂岩的成岩共生序列和形成片钠铝石的CO2的成因。

However, dawsonite can be acted as trace mineral suggesting migration or accumulation of fluids with abundant carbon dioxide to whatever origin it belongs. In geological background, occurrence or enrichment of dawsonite indicates that migration or accumulation of carbon dioxide with large scale has happened.

然而，不论源于有机成因CO2气还是无机成因CO2气，片钠铝石均可作为富CO2流体运移或聚集的"示踪矿物"，地质过程中片钠铝石的出现或富集表明该区曾存在大量CO2运移或聚集。

Dawsonite is an orthorhombic, hydrated sodium aluminium carbonate appearing as radial, bunchy, trichoid platy collective and so on, filling in the pores among the grains, or as replacement of feldspar and detritus partly or on the whole, dawsonite is a kind of authigenic mineral which formed latest.

片钠铝石是一种斜方晶系、含水、钠和铝的碳酸盐矿物，砂岩中的片钠铝石是最晚形成的自生矿物之一，一般以放射状、束状、毛发状、板状等分布于砂岩的孔隙中或交代长石和岩屑等。
