First, For the coronary artery stent, two kinds of loads, including the pressure named 〓 derivatively from the balloon and the counterforce named 〓 on the wall edge of the stent, have been taken into account in the analysis of the stent.〓 and 〓 were changing as the stent expanding. So, the expansion process of the stent could be considered as the process composing of many extremely short equilibrium processes, where 〓 and 〓 could be regarded as constants and the stresses, the strains and the displacements were obtained using NFEA in every processes. Then, the stresses, the strains and the displacements obtained in every processes or steps were added up to get the final structure of the coronary stent.
首先,解决了支架有限元分析的载荷非线性问题,认为医用心血管支架受到两种载荷的作用:球囊直接传递的压力〓和球囊对不锈钢支架丝壁边缘的反作用力〓,这两种载荷在支架分析中必须都考虑进去;〓为非线性载荷,随着支架扩张不断变化,处理时将支架扩张的整个过程看成由37个很短的平衡过程组成,在每个过程中取〓为常量,采用有限元法获得应力、应变、位移,最后将各过程的应力、应变、位移迭加起来就获得了不锈钢支架总的应力、应变和位移;本研究用变分法和有限元法模拟杆件拉伸证明了上述方法是合理的。

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。
