成岩作用

Organic acid played an important role in the process of reservoir diagenesis.

6有机酸在储层成岩过程中起着重要的作用。

The grain size of sediments has an important role in the early diagenesis of nitrogen.

在氮的早期成岩过程中，粒度也起着非常重要的作用，沉积物的粒度越细，沉积物中有机氮的分解速率越小，即细粒度沉积物中有机氮的分解矿化速率最小，易于富集有机氮。

ABSTRACT As a significant kind of fluid medium, the geofluids play a very important role in the processes of diagenesis and mineralization....

地质流体作为重要的流体相介质，在各种成岩成矿作用过程中起着十分重要的作用。

Strong compaction is the most typical diagenesis as well as the principal factor of reduing porosity.

压实作用强烈是北山地区侏罗系煤系砂岩最具特色的成岩现象，也是使孔隙减少的最主要因素。

The result shows that the oil-water contact is controlled by the structure,fault,sand distribution,petrophysical property and diagenetic epigenesist and is an irregular dip plane;reserves distribution is well related to the distribution of braided channel micro-facies in the.

结果表明：油水界面受构造、断裂、砂体展布、物性和成岩后生作用等多因素控制，为一不规则的倾斜面；储量分布与扇三角洲平原亚相的辫状水道微相分布具有较好的相关性；辫状水道微相是下一步扩边挖潜的有利目标。

The result shows that the oil-water contact is controlled by the structure, fault, sand distribution, petrophysical property and diagenetic epigenesist and is an irregular dip plane; reserves distribution is well related to the distribution of braided channel micro-facies in the fan delta plain; the braided channel micro-facies is a favorable target of extension in next step.

According to the experimental results of Watson (1978), and Ryerson and Hess (1980), pertaining to the distribution of trace elements between basic and acidic liquids in the temperature above magmatic liquidus, and the investigation of Webster (1997) on the melt inclusion in pegmatitic quartz from Ehrenfriedersdorf ore district, Germany, it should be drawn that there probably exists the liquid immiscibility in the early stage of pegmatitic evolution, due to the perphosphorus content in the magmatic systems. The perphosphorus feature of the melt is of great impact on the petrogenesis and matellogenesis of pegmatites.

1997对德国Ehrenfriedersdorf矿区伟晶岩石英中熔体包裹体的研究成果，我们推断在富磷岩浆体系中，在其演化的早期将出现由磷引起的液相不混溶作用，它对伟晶岩成岩和Be的成矿具有重大的影响。

According to the mineralization of Cu-Ni and Pt-Pd deposit, Cu-Ni sulphides were formed by liquation in the late phase of fractional crystallization of magma chamber, and the Pt-Pd mineralization mainly occurred on the process of fluid action after diagenetic stage.

就铜镍和铂钯矿化而言，铜镍硫化物形成于岩浆房分离结晶晚期的熔离作用，而铂钯矿化则主要在成岩期后流体作用阶段形成。

Study of the gas generation and petroleum systems indicates that these two depressions have good gas reservoiring conditions and are very important prospects for gas exploration in the western Taiwan Basin.

通过对烃源岩成烃作用和含气系统的分析认为，以上2个坳陷具备天然气成藏的良好时空配置，是台西盆地天然气勘探的重要前景区。

There are three evolution paths for the kaolinitic rocks in the diagenesis:one is that kaolinite is transformed to the mixed minerial of kaolinite/dickite and dickite in the acid environment; the second is to be trnasformed to the ammonium illite,chlorite and pyrophyllite in alkaline environment;The third is to be transformed to well ordered kaolinite in the superfacial environment. The highly orderization of kaolinite may be related to the hot solution underground.

提出煤系高岭岩三种成岩演化轨迹；一种是在酸性环境下朝高岭石/地开石间层矿物和地开石方面演化；另一种是在碱性环境中朝氨伊利石、绿泥石和叶腊石方向演化；第三种是在表生环境种朝高度有序高岭石方向演化，高岭石的高度有序化可能与热水溶液作用有关。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
