蜀南地区南井构造井9系统茅口组气藏气水关系研究 摘要 碳酸盐岩储集层是世界上主要的储集层之一，也是世界上产出油气最多的储集层。在经历了沉积、成岩、成岩后生变化(充填与溶蚀)和构造变形等复杂演化过程之后，形成了碳酸盐岩缝洞系统。在四川盆地碳酸盐岩缝洞系统中，溶洞是主要的储集空间，而缝洞是主要的渗滤通道。本文运用各种已知资料对蜀南南井构造井9缝洞系统茅口组气水关系进行研究。首先划分各井的生产层段，研究产层段岩性特征，然后画出连井剖面图，对区域原始气水关系有一个直观的了解。之后对区域各口井以及整个缝洞系统进行详细地气水关系研究以及储量计算。最后提出对于该缝洞系统气水分布的认识，以及对整个区域生产的建议。 关键词：蜀南；南井构造；茅口组；碳酸盐岩储藏；缝洞系统；气水关系  Study on gas-water relationship in Maokou of the Ninth well system in Nanjing .in southern Sichuan province Abstract：Carbonate reservoir is one of major reservoirs, and it is also the most productive reservoir. After the sedimentation, diagenesis, post-diagenetic changes (filling and erosion) and the evolution of tectonic deformation, the carbonate fracture-vuggy system come into being. In carbonate fracture-vuggy system of Sichuan Basin, cave is the main reservoir space, while the fracture is the main permeable channel. In this paper, a variety of data is used to research the gas-water relation of Maokou of the second well system in Nanjing of southern Sichuan province.First of all, the productive layers are divided. Then we study on the lithology characteristics of the productive layer and plot (profile of well). After we have an intuitionistic understanding of the original gas-water relation of this area, we(the paper ) start a detailed reaserch on the gas-water relation of the wells in this area and the fracture-vuggy system, and begin to do reserve calculation.Finally, we bring forward our understanding of the gas-water distribution of the fracture-vuggy system, as well as the advice on the production in the whole area. Key words: the southern Sichuan Province;Nanjing; Maokou; Carbonate reservoir;fractured - vuggy system; gas-water relationship. 目录 摘要 I 第1章 前言 1 1.1 选题依据以及研究意义 1 1.2 碳酸盐岩缝洞系统气藏气水关系研究简介（前言中没有国内外研究现状吗） 1 1.3本文研究的主要内容和技术路线 2 1.3.1主要内容 2 1.3.2技术路线 3 第2章 研究区域概况 4 2.1自然环境 4 2.2勘探开发简况 5 第3章 气藏地质特征 7 3.1构造特征 7 3.2储层特征 8 3.3 流体与流体分布 10 3.4压力与温度 11 第4章 井9缝洞系统气水关系分析 11 4.1生产概况. 11 4.2产层段划分 13 4.3单井动态特征分析 15 4.3.1井2井 15 4
