松辽盆地孤店二氧化碳气田储集砂岩中含有大量片钠铝石，根据其特征可以查明注入CO2气形成的自生矿物与CO2成因之间的联系。

Optical microscope, scanning electron microscope and X-ray diffraction analysis have revealed that dawsonite mainly occur in the feldspar-rich sandstone and pyroclastic rocks, either as cements filling inter-grain pores as radical, bunchy, rosette, intricately trichoid, and platy collectives, or as replacement of feldspar and lithic grains with bunchy and paty shapes.

片钠铝石主要发育在油气储层或CO2气储层中富含长石的砂岩和火山碎屑岩中。在含片钠铝石砂岩和火山碎屑岩中，片钠铝石以放射状、束状、杂乱毛发状、球状和板状等集合体充填孔隙，或呈束状和板状交代长石和岩屑。片钠铝石及其共生的铁白云石都是最晚形成的自生矿物组合。

By integrating the multi-discipline methods of petroleum geochemistry, sedimentology, hydrogeology, petroleum geology and experimental geochemistry, the thesis has carried out experiments of microcline dissolution in solutions with organic acids, crude oil, brines with high total dissolved solids , and has dealt with Al distribution between the crude oil and the brines after the experiments.

In Sample TVG-1,aragonite is replaced by calcite and the pseudomorph of the former is observed,suggesting that this sample was formed earli...

扫描电镜显微结构特征显示，自生矿物主要是通过细菌的厌氧氧化作用，直接从冷泉中沉淀出来的。

According to authigenetic mineral association and nowadays stratum geochemistry character, combining the diagenesis character of sandstone in coal measure strata, it is thought to the fluid of outcrop sandstones went through ealy acidity- acidity-alkality-surficial acidity 4 fluid phases, the fluid evolution of core sandstones is ealy acidity- acidity- nowadays alkality 3 fluid phases.

由自生矿物组合以及现今地层水地球化学特征，结合煤系地层砂岩成岩作用特征，认为露头砂岩的流体经历了早期酸性－酸性－碱性－地表酸性4个流体阶段，岩芯砂岩的流体演化为早期酸性－酸性－现今碱性3个流体阶段。

The temperature of authigenic minerals is a key to quantitative research of diagenetic history.

自生矿物的形成温度是成岩史定量研究的敲门砖。

Authigenic mineral assemblage formed in different ambients is distinct to each other.

两种环境下形成的自生矿物组合截然不同。

Secondly, the authigenic mineral hydrocarbon inclusion technology is in application, which makes hydrocarbon phase state during secon.

其次，是自生矿物烃类包裹体技术的应用，对于油气二次运移中烃类相态的判断，更加明确和可靠。

Chlorite is a common authigenic mineral lining the pores of sandstones.

绿泥石是一种常见的自生矿物，作为砂岩孔隙的内衬。
