New ideas and methods in the paper:1 The formulas on perforated casing collapse strength were deducted, which offereda convenient method to analyze the relationship between casing collapse strength and perforation;2 The stress and displacement formulas on the system of casing, cement anddeformation under the non-uniform load were deducted, which offered the theoretical found for designing optimally casing string;3 The relationship between structure in-situ field of whole oil field and casing failurewere studied, which offered the scheme for the prediction of casing failure. The process of study in the paper:1 For simulating the relationship between the structure in-situ field and the casingfailure in the oil-deformation, the tests of the uniaxial tensile, compress, tnaxial compress and dilatability were made on the samples of the drill cores from deformation of casing failure position in Yuejing II oil field.

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。
