1、图分类号:TE347单位代码:11414学号:2014292019题目深海断块油藏开发方案设计—以A油田为例学科专业油气田开发工程研究方向油气田开发理论与系统工程硕士生阿娜尔指导教师李相方教授二○一七年五月摘要摘要随着当今世界经济快速发展,我们对于能源的需求逐渐扩大,针对深海断块油藏的开发也提上日程。但是,由于海上油田自身的特殊性,国内又缺乏深海油田开发相关经验,深海油气田的开发面临巨大挑战。本文以国外A油田一个中孔中渗砂岩中轻质低粘深海断块油气田为例进行深海小断块油藏开发方案设计,经过研究得出四项成果:(1)设计了一套适合深海小
2、断块油田的开发设计方案;(2)准确研究了A油藏的各方面特征,其中包括其储层物性、流体性质、孔隙结构、层位分布、构造特征、和压力系统等,经过这些研究对类似深海小断块油藏有了更加深刻的认识;(3)建立了包含地质构造、断层特征、及储层物性的三维地质模型,并得出了适合类似A油藏的深海小断块油藏的地质建模方法;(4)针对A油藏提出了三套开发方案,经过对比分析得出了最优开发方案,其中推荐全区新布5口水平,并将部分探井改造为生产井。通过总结国际深海断块油藏开发的经验,并结合中国海上油田开发特点,形成了一整套深海小断块油藏的开发技术,对海上油田的
