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。

Based on the study of hydrochemical characteristics of formation water, the distribution of palaeohydrodynamic field in main oil-gas migration period and its influence on hydrocarbon migration and accumulation in Gaoyou sag were discussed.

By the types of oil or gas reservoirs, three kinds of oil or gas accumulation models fit to Wuerxun depression. They are the model of oil or gas migrating and accumulating in sandstone lens or fracture traps of source rock, the model of oil or gas accumulating in fault-block or fault-screened traps through vertical migration, the model of oil or gas accumulating in structural-lithological traps migrating laterally in short instance through sandrock.

在此基础上，根据油气藏类型总结出乌尔逊凹陷南二段油气成藏模式有①源内砂岩透镜体或裂缝圈闭油气运聚成藏模式②油气沿断裂垂向运移于断块或断层遮挡圈闭成藏模式③油气沿砂体短距离侧向运移于构造—岩性圈闭油气藏模式。

Fluid dynamics is the dynamic frame and background of hydrocarbon migration and accumulation,and is fundamental factor influencing migration and accumulation of hydrocarbon.

流体动力学构成了油气运聚成藏的动力学框架和背景[1]，通过开展以流体势和异常高压为主要内容的流体动力研究，有助于分析油气的运移、聚集和成藏作用。

A important feature in research region is: synsedimentary motion of faults result fault block"tilting movement"and change hydrocarbon migration direction as well as forming fault-bock trap in the center of resource rock, This is favorable for fault-block traps to accumulate hydrocarbon.

本区的另一个重要特征是断裂同沉积活动引起的掀斜运动改变了区域油气运移的方向，在烃源岩发育的沉积中心形成掀斜断块构造圈闭，有利于油气的聚集。

Let students to be familiar with the basic characteristics and formation mechanisms of oil-gas, to grasp the evaluating indexes of source rock, reservoir, seal and oil-gas reservoir, to grasp the styles of source-reservoir-seal association, the features of oil-gas migration, the conditions of forming oil-gas reservoir, the factors of oil-gas reservoir damage and the regularity of oil-gas reservoir formation.

Fluid flow and component transport in fractured porous media are very important for understanding metallic ore formation,oil and gas migration,and transportation of pollutes and has attracted extensive investigations in recent two decades.

：断裂多孔介质中的流体流动和组分输运过程对于理解金属成矿过程、油气运移、污染物质的输运和分布十分重要，近 2 0年来得到了广泛的研究。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
