海拉尔油田使用油藏开发设计_毕业论文初版.doc

摘 要 油藏开发设计是油田开发的总体规划和具体实施的全面系统的计划和部署，是油藏投入开发的基础和依据。海拉尔油藏属于典型的低渗透古潜山油藏，具有良好的勘探前景，所以设计科学、先进、合理的开发方案是海拉尔油田始终遵循的一条基本原则，也是油田开发取得高水平、高效益的首要关键。 本文主要阐述了海拉尔油田的概况，油田地质特征，油藏工程设计以及方案实施要求等内容。本设计首先介绍了海拉尔油田的地貌特征以及生成的油气藏组合，为以后的设计提供了初步的判断；然后分析了油藏的构造特征与储集特征，为以后的设计提供依据；接着根据实际的情况判断出该油藏属于正常压力与温度下的油藏系统以及原油的性质；然后根据储集层的渗流物性特征做出相对渗透率曲线。最后，通过不同的方法确定了该油田的开发方式，井网与井距以及采收率。 关键词：油田开发，方案设计，采收率 Abstract Reservoir development design is the overall planning of oilfield development and the implementation of the comprehensive system plan, deployment, and it is the basis for development of reservoir input. Reservoir of low permeability is typical of the reservoir belongs to the Ancient hide reservoir, and it has good exploration prospects, So design science, advanced and reasonable development plan is always a basic principle of Reservoir of Haliar , it is also the primary key to have a high level of oilfield development. This paper expounds the general situation of the oil field, oil field geological characteristics, reservoir engineering design and plan implementation requirements, etc. This design first introduced the features of the landscape, oil field features and generated combination of reservoir, design provided the preliminary judgment for the following; Then analyzed the structural characteristics of the reservoir and reservoir characteristics, provides the basis for the following design; Then according to the actual situation of the judgment that the reservoir belongs to the normal pressure and temperature and the nature of the crude oil reservoir system; And then based on the reservoir physical property characteristics of seepage make relative permeability curve. Finally, through the different methods to determine the oilfield development mode, the well nets and well spacing and recovery.
