查询词典 metasomasis

There is a symmetric sedimentary rhythm with a polyhalite center in this deposit,formed by the cogenetic metasomasis of relic concentrate d brine with gypsum in shallow basin of the gypsum flat environment above tidal level and the evaporation sedimentation of the mixture of gypsum flat drainage water with rilic concentrate brine.

矿床具有以杂卤石矿为中心的对称沉积韵律，一方面是潮上膏坪环境浅水盆地中的残余浓缩卤水与石膏发生同生交代作用形成，另一方面又是膏坪汇流水与残余浓缩卤水混合蒸发沉积而成。

Depth of the research section is from 2100m to 4200m, which change is larger and types of diagenetic including compaction pressure,solution, cementation, metasomasis, re-crystallization and the transformation of clay minerals.

研究区段埋深2100m—4200m，变化较大，成岩作用类型有压实压溶、胶结、交代、重结晶和粘土矿物的转化。

Diagenesis types include compaction,cementation, solution and metasomasis.

成岩作用类型主要包括压实作用、胶结作用、溶解作用和交代作用，其中胶结作用使储层原生孔隙迅速变差，而溶解作用是次生空隙发育的主要因素。

Base on core observation and grain size analysis, and under associated consideration of logging trace characteristics, Chang8 reservoir in study area is classified into three sedimentatal microfacies, subsea river, mouth bar and river flank.3.The mian diagenesis in study area are: mechanical compaction, cementation, metasomasis and denudation in late diagenetic phase.4. In allocation of reservoir macroscopic heterogeneity, more heterogeneticer reservoir, class 1 and class 2, mainly locate in the center of subsea river or crook and divaricate of the river; class 3 and class 4 mainly locate in river flank, and the physical property of these locality are better.5. Diagenesis of reservoir have influence on the pore structure which influences the reservoir microscopic heterogeneity. The better the pore structure is, the slighter the reservoir microscopic heterogeneity is; on the contrary, the reservoir microscopic heterogeneity is serious.

本次研究所取得的主要成果及熟悉有：1、将合水地区长8储层细分为6个小层：长8_1~1、长8_1~2、长8_1~3、长8_2~1、长8_2~2和长8_2~3.2、依据岩心观察和粒度分析，并结合测井曲线特征，研究区长8储层分为水下分流河道、河口坝和河道侧翼四种沉积微相。3、研究区主要经历的成岩作用有：机械压实和压溶作用、胶结作用、交代作用、晚成岩期溶解作用。4、从宏观非均质性平面展布特征来看研究区宏观非均质较强的1类和2类区主要分布于水下分流河道中间或河道拐弯和分又处。3类和4类往则主要分布于水下分流河道侧翼，这些地方储层均质性相对较好。5、储层成岩作用影响储层的孔隙结构，储层的孔隙结构又对储层的微观非均质性有不同程度的影响，孔隙结构越好，则储层的均质性越好，储层的孔隙结构差，则非均质性强。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
