摘要通过分析凝析气藏的相图,建立了凝析液饱和度随压力降的变化规律,并回归得出了相应的公式;同时通过对气体压缩因子、黏度随压力、温度的变化,建立了这些参数和无因次压力的关系;在双重介质地层假设的基础上,建立了在试井过程中凝析气相对渗透率随凝析液饱和度变化的凝析气藏试井解释数学模型,采用隐式迭代的方法进行了求解并进行了参数敏感性分析;结果表明:凝析液的饱和度对凝析气藏试井的压力及压力导数曲线有着很大的影响,早期由于凝析液的析出,阻碍了气藏的流动,导致压力及压力导数曲线上升;在凝析液饱和度达到峰值之后,随着凝析液的挥发,凝析气的相对渗透率逐渐恢复,压力及压力导数曲线又回归到正常的径向流位置;由于裂缝和基岩之间的压力差,使得裂缝弹性储容比在测试过程中发生变化,进而影响了压力及压力导数;窜流系数和裂缝弹性储容比的变化决定了窜流段发生的早晚和程度;而基岩中气体黏度的变化使得窜流的发生稍微滞后。

Experiment shows that both the dry plate pressure drop and the wet plate pressure drop increase with the increase of the kinetic energy factor in plate hole but have no influence of the height of cap. The wet plate pressure drop linearly ascends as the clear liquid height increases. Liquid lift-up increases at first then decreases with the increasing of the kinetic energy factor in plate hole, increases with the clear liquid height increasing and the height of cap decreasing, but as the kinetic energy factor in plate hole increased, the influence of height of cap will gradually decreased.

5The distribution patterns of rare earth element compositions in the hydrothermal components are similar to that of pacific seawater. This infers the complex and significant interactions of hydrothermal fluid with surrounding seawater during its diffusing process. Dissolved trace metals in the hydrothermal fluid can be removed by settling terrigenous or biogenic particulates and precipitated quickly from the hydrothermal plume round the vent. On the other hand, hydrothermal particulates would also scavenge some elements from the seawater to coprecipitate into the sediments.

The results indicated that both binary interactive parameters of water/isobutanol system from this work and the parameters of water/ethanol from literature can be used to precdict the liquid-liquid equilibria of water/ethanol/isobutanol. But the parameters of ethanol/isobutanol from the literature were not appropriate for the prediction. Furthermore, the model parameters from 30℃ can can be used to predict the liquid-liquid equilibria under 35 ℃. The model parameters of water/isobutanol are independent on the temperatures, so constant parameters irrelative to temperature can meet prediction accuracy. Othmer-Tobias/Bancroft equation was also used to fit the liquid-liquid data of water/ethanol/isobutanol system, but it didnt possess the performance of predicting the liquid-liquid equilibria.The partition coefficients of dipotassium glycyrrhizinat were determined in the liquid-liquid two-phase system of water/ethanol/isobutanol and corrected by experiential equation.
