First, we investigate the methods of sepiolite s purification from ore , from which we get the incompact short fibrous sepiolite for the experiment ; the prime activatited term is also obtained through this experiment. We use activated sepiolite to process the absorption experiment on heavy meatal ion ( Ni2+, Cr6+, Pb2+, Cu2+, Cd2+), noble metal ion, dynamite cotnposton in water and industrial oil. we take Ni2+ for example to confirm the prime adsorbent term , from the experiment we get the adsorbent isotherm . Make the dynamic absorption experiment and regenerate experiment using sepiolite on the heavy metal(Ni2+) on the base of static absorption experiment.
我们首先研究了从矿石中提纯海泡石的方法,制得供实验用的松散短纤维状海泡石;通过实验确定了最佳活化条件;进行了活化后的海泡石对重金属离子Cr~(6+、Pb~(2+)、Cu~(2+)、Cd~(2+)、贵金属离子、水中炸药组份、工业油的吸附实验;以Ni~(2+)为例选择了最佳吸附条件;通过实验作出了以上各组分的吸附等温线;在静态吸附实验的基础上进行了海泡石对重金属Ni~(2+的动态吸附实验及再生实验。

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。
