摘要： 准噶尔盆地莫北2井区侏罗系三工河组油藏为一典型的气顶油藏,气顶体积是油环的0.91倍。应用数值模拟方法，围绕确定气顶油藏的合理开发方式展开研究。在经过历史拟合修正地质模型的基础上,围绕三工河组油藏采用衰竭式开采、注水开发及注水方式、注采比、气顶开发等进行方案设计模拟。模拟结果表明，该油藏宜采用在油水界面内缘与油气界面外缘部署两排注水井注水开发,注采比保持在1.0,同时应在气顶布署一口平衡气井开发油环可获得较高的采出程度。

Abstract: The Jurassic Sangonghe reservoir in Mobei-2 W ellblock is a typical gas-cap pool where the gas cap volume is 0.91 times as big as itsoil ring's. With the application of reservoir numerical simulation method, the rational development process for gas-cap pool is studied. The sim-ulation and design of various processes such as depletion drive, waterflooding, injection-withdrawal ratio and gas-cap production, etc., are per-formed,based on modified geological model by production history matching of Sangonghe reservoir. The simulated results show that it is themost favorable to adopt waterflooding process that two rows of injection wells are arranged respectively in inner part of oil-water contact and out-er part of oil-gas contact, and keep injection-withdrawal ratio of 1.0; simultaneously, an equilibrium gas well to be drilled on the gas cap for oilring development is available to obtain higher recovery percent of reserves.

Key words: Junggar basin, Gas-cap reservoir, numerical simulation, water flooding, recovery percent
