摘　　要：针对D229块超稠油油藏厚度相对较薄、地层具有一定倾角的地质特点,利用油藏工程、数值模拟、分析类比等方法,对其SAGD试验进行优化部署设计。研究结果为:采用双水平井SAGD方式部署,注汽井位于采油井的斜上方,水平井走向与构造线方向平行,水平井排距70～100m,水平段长度360～450m。预计SAGD阶段可生产6a,试验区最终采收率达59.63%。该项研究对具有一定倾角的中深层超稠油油藏的开发具有重要的指导作用。Aimed at the geology characteristics of thin bed and the stratum with a certain inclination in super heavy oil reservoir of Block D229, this paper uses the reservoir engineering, numerical simulation, analysis analogy and other methods to optimize the deployment of SAGD pilot design. The results show when it uses the double horizontal wells in SAGD pilot to deploy, the steam injection wells locate at the top of the ramp production wells, horizontal wells run parallel to the direction of structure, horizontal wells distance is from 70m to 100m and the length of the horizontal section from 360m to 450m. SAGD phase is expected to produce for six years and the ultimate recovery of test area will be up to 59.63%. The study has a certain guiding role for the development of deep extra-heavy oil reservoir with a certain inclination.
