With the investigation of the domestic and foreign literature systematically, the bases on the domestic and foreign present research and the comprehensive utilizations of the various knowledge of fluid mechanics in porous medium, reservoir engineering, mathematical physics, perforation completion, numerical simulation and so on, this article takes numerical simulation of gas reservoir of water solubility as the research aim which has completed following research works and obtained the corresponding research results: it analyzes the nature of the Water-soluble gas and formation water as well as the influent factors of the solubility through the study of massive materials; It establishes mathematical models three-dimension, the dual medium, the gas-water phase through the way of finite difference in the migration of water-soluble gas, which describes the entire process of release, migration and production in formation, where it considered the problems of variable bubble point; According to the numerical models of gas reservoir of water solubility it provides solution procedure that based on black oil model; It discovers that there will obtain the good effects in the lowly speed of development through simulation; the reinjection of formation water may largely enhance the produce degree of water-soluble gas when we consider reinjection in simulator; It considered the influence of perforated completion on development so as to increase the simulator"s versatility, It discovers that the simulator may reflect the conditions of development when we exanimate he simulator"s reliability with the empirical datum.
本文以水溶性气藏数值模拟研究为研究目标,在系统调研国内外文献、深入分析国内外研究现状的基础上,综合利用渗流力学、油气藏工程、数学物理方法、射孔完井以及数值模拟理论等多方面的知识,完成了以下研究工作并取得相应的研究成果;①通过对大量的资料调研,分析了水溶气、地层水性质、储层地质性质以及影响气体在水中溶解度的因素。②考虑到由于高压产生的大量水力裂缝,采用有限差分方法建立水溶气运移的三维、双重介质、气-水两相全隐式数学模型,该模型描述了水溶气在地层中的释放、运移和采出的整个过程。③在原有黑油模型的基础上,根据水溶性气藏数值模型编制了该数值模型的求解程序,该程序可以求解单重、双重介质两种情况。④通过模拟不同开采速度对水溶气开发效果的影响,发现开采速度较慢的时候可以取得较好的开采效果。⑤在模拟器中考虑了注水对水溶性气藏开发的影响,地层水回注可以大幅度提高水溶气的采出程度。⑥为增加模拟器的通用性,在模拟器中考虑了射孔完井方式对开采的影响。⑦检验模拟器计算的可靠性,发现在使用实验数据对水溶性气藏进行模拟时,模拟器可以很好的反映气藏开发的状态。

The dramatist and musical characters and the perfect combine between music and drama are the purports. The thesis is divided into three parts: the preface, four chapters and the conclusion. In the preface it is explained that what in this thesis is expounded and what kinds of study about the opera there are in Chinese and in the other area of the world. The first chapter is a summary about Gounod and his"Faust", which is the typical work in lyric operas. In the second chapter analysis on drama, the character and figures of the roles in the opera is made, and the characteristic of the plot ,the creation of opera and framework is put together. In the third chapter the music in the opera is studied, and the characteristics are put together on the base of particular analysis on typical passage of aria chorus ensemble. In the last chapter, perfect combine between drama and music is presented by study on Faust's character and psychology,and it is discussed that music implied the plot. And the conclusion is a whole comment of the opera and it's musical characteristics

Pillared montmorillonite, as a representative of Sandwich like pillared interlayered clays ,caught many scientist"s attention not only because of its special structure of two-dimensional sheets but also its excellent activity of catalysis and adsorption. It is well documented that the method to prepare PILM, ion-exchanging, needed a long periods and was affected by many factors, and that the product had low thermal stability especially hydro-thermal stability which was the primary obstruction of its using in large-scale production. At the same time, PILM was well documented prepared with Na-montmorillonite, while there were a few documents about PILM prepared with Ca-montmorillonite. The large cost of remodel of Ca-montmorillonite to Na-montmorillonite was another obstacle of the application of PILM, while Ca-montmorillonite was widely distributed in nature, as a result, to prepare PILM with Ca-montmorillonite has practical significance. What"s more, PILM was mainly studied as a catalyst in oil refining process till now, but rarely documented in other catalysis reactions, especially in coal liquification filed which also needed high activity catalyst.
以柱撑蒙脱石为代表的具有"三明治"结构的柱撑粘土矿物因其特殊的二维孔道结构和优良的催化和吸附性能近年来成为国内外广泛关注和研究的热点,但是目前国内外大量报道的PILM制备大多采用离子交换法,生产周期很长,影响因素很多,并且产物热稳定性不够高,特别是水热稳定性较差,这是其不能在实际中大规模生产和应用的主要障碍,因此制备一种高稳定性的PILM意义非常;文献中大量报道的都是钠基蒙脱石合成的柱撑粘土矿物,传统的离子交换法必须将钙基蒙脱石钠化改型,其成本相当高,而自然界中大量存在的却是钙基蒙脱石,直接用钙基蒙脱石合成柱撑粘土矿物有很现实的意义,但目前这方面的报道却很少见;另外,迄今为止,PILM作为催化剂的研究领域主要在石油的炼制中应用,而在煤炭的液化中却鲜有报道,如果能在煤炭转化领域应用这一成果,其影响也将是相当大的。
