Abstract: LD1 block is an ordinary heavy oil reservoirs of high porosity and permeability with characteristic of small reserves, thin reservoir thickness, and sufficient energy of edge water. With the limit of low single well controlled reserves of vertical wells and high drilling cost, it is difficult to exploit the block. Development and application of horizontal wells have obvious advantages in such reservoirs, so study about horizontal well deployment is started. Edge water has a great influence on exploitation of heavy oil reservoir using steam stimulation. In order to maximize economic benefits, sensitivity study in permeability, oil saturation and water energy are carried out.The length of horizontal well and the height of water avoidance are optimized to improve the effect of single well development and oil steam ratio, delay the water invasion, and provide reference for the same kind reservoirs.

摘要： L D 1区块储量小、 油层厚度薄、 边水能量充足, 为高孔高渗普通稠油油藏。受直井开发单井控制储量 低、 钻井成本费用高等因素限制, 一直处于难动用状态。应用水平井开发此类油藏具有明显的技术优势, 因此开展 水平井部署研究。边水对稠油油藏蒸汽吞吐开发效果具有较大影响, 为了实现经济效益的最大化, 开展渗透率、 含 油饱和度和水体能量等油藏敏感性研究, 优化设计水平井段长度、 避水高度来提高单井开发效果, 延缓水侵, 提高油 汽比, 为同类油藏的开发提供借鉴。
