分析了砂岩型铀矿的国内外研究现状和发展趋势,尝试从成矿系统演化论的角度提出新的研究思路：即,以系统观为指导,以物质迁移的动力学为主线,从区域地质背景演化,特别是构造动力演化、岩相古地理等方面入手,恢复矿前期、成矿期、矿后期的区域古地形格局。运用融入了地下水流动系统理论的古水文地质分析方法,重建区域演化进程中各地质时期的古流场。着重从区域尺度上研究矿质的源-迁移-汇（成矿）-保存的动力学过程。     

Fractal-like adsorption kinetics of Pb^2＋ in rocks

The adsorption kinetics of Pb^2＋ in rocks has been studied using ion selective electrodes and atomic absorption spectrophotometer. The results showed that the adsorption process is a fractal-like reaction. The adsorption rate was relatively high before 30 minutes, and then dropped. The saturated adsorption capacity （a） of Pb^2＋ and kinetic parameters （b, a, D and k） increased with increasing initial concentrations of Pb^2＋. These parameters （except a） decreased while Na^＋ was present in the solution. Furthermore, the smaller the rocks were in grain size, the bigger these kinetic parameters would be, though the parameter a was almost constant.     

Formation Dynamics and Quantitative Prediction of Hydrocarbons of the Superpressure System in the Dongying Sag

Based on the theory of formation dynamics of oil/gas pools, the Dongying sag can be divided into three dynamic systems regarding the accumulation of oil and gas： the superpressure closed system, the semi-closed system and the normal pressure open system. Based on the analysis of genesis of superpressure in the superpressure closed system and the rule of hydrocarbon expulsion, it is found that hydrocarbon generation is related to superpressure, which is the main driving factor of hydrocarbon migration. Micro fractures formed by superpressure are the main channels for hydrocarbon migration. There are three dynamic patterns for hydrocarbon expulsion： free water drainage, hydrocarbon accumulation and drainage through micro fissures. In the superpressure closed system, the oil-driving-water process and oil/gas accumulation were completed in lithologic traps by way of such two dynamic patterns as episodic evolution of superpressure systems and episodic pressure release of faults. The oil-bearing capacity of lithologic traps is intimately related to reservoir-forming dynamic force. Quantitative evaluation of dynamic conditions for pool formation can effectively predict the oil-bearing capability of traps.

天然气溶解过程中组分分馏模型及其应用

天然气不同组分在水中溶解度的差异,导致溶解相与残留游离相天然气组分组成不同,即发生组分的溶解分馏效应。溶解分馏效应在天然气水溶运移、溶解散失等过程中均有发生。揭示天然气组分的溶解分馏规律、建立定量分馏模型,有助于天然气气源对比和成藏过程示踪。以Henry定律为依据,对不同组分溶解特征分析,提出了溶解度分数的概念,并建立了溶解分馏模型。根据该模型和各组分的溶解度分数和天然气溶解量,可计算各组分的溶解分馏量,恢复天然气初始组成特征。计算表明,威远震旦系气藏初期的天然气组成为:CH4为72.70%,C2H6为0.09%,CO2为22.41%,N2为4.07%,干燥系数(C1/C1-5)为99.876%。溶解作用使天然气中CO2含量显著降低,烃类气体含量增加,而天然气干燥系数降低。结果有助于天然气成因判识和气源对比等。     

准噶尔盆地西北缘克-百地区不整合面及其动力学条件

不整合及其性质和强度的确定对理解克拉玛依至百口泉地区构造变形历史和油气聚集规律具有重要意义。根据地震资料研究显示,该区二叠纪至中生代地层中存在多个不整合面,且多为构造运动的反映。其中对克-百地区构造形成具有重要影响的有四期,其一发生在中二叠统下乌尔禾组沉积后,主要表现为冲断掀斜运动,使其前的二叠纪沉积向南东方向掀斜抬升,遭受剥蚀;其二发生在三叠纪末期,对克百断裂上盘大侏罗沟断层至百口泉段的构造有重要影响;其三发生在中侏罗世末,该期构造运动在克百断裂带及其上盘表现最为清楚,以冲断为主,局部地区有褶皱现象;其四发生在早白垩世末期,表现为掀斜运动,褶皱和断裂作用相对较弱。克-百地区不同时期、不同构造部位变形的差异性与构造动力条件密切相关。     

应用生烃动力学法研究川东上二叠统烃源岩生烃史

现今川东上二叠统烃源岩生烃史研究具有局限性.首先,没有对上二叠统Ⅰ-Ⅱ1型灰岩生油、Ⅲ型泥岩的生气史分开评价;其次,海相镜质组反射率通过拟合公式换算成镜质体反射率评价烃源岩成熟度具有局限性.针对上述不足,笔者通过热模拟实验,利用化学动力学方法,标定出两类源岩生油、生气的动力学参数,并结合川东地区的埋藏史及热史,模拟出源岩有机质的成烃转化率曲线.研究表明:上二叠统灰岩、泥岩有机质在距今200 Ma和190 Ma分别进入了生油、生气门限,而在距今170 Ma和140 Ma生烃结束.
