摘要/Abstract

摘要：

通过对不同物性的岩心样品进行核磁共振分析和驱替实验，探讨了渤海湾盆地柳赞地区古近系沙河街组Es₃²⁺³油藏地层倾角与含水率对驱油效率的影响，并通过构建以注采参数为核心的二维模型，揭示了影响气液界面稳定性及驱替效果的关键因素。研究结果表明：①柳北Es₃²⁺³高倾角油藏水驱转气驱过程中，顶部注气技术提高了约20%的驱油效率，主要受控于重力分异作用所形成的稳定气顶及其所主导的非混相驱替机制，而直接重力作用对驱油效率的提高相对有限。②通过适当提升注采比可增强气顶压力及气体渗入微孔隙的能力，从而改善气液界面的稳定性。③稳定注气速度公式可有效预测注气重力驱的最佳注气速度范围，可实时分析注气开发动态。

Abstract:

By conducting nuclear magnetic resonance analysis and displacement experiments on core samples with different physical properties, the influence of formation dip angle and water cut on oil displacement efficiency in Es₃²⁺³ reservoir of Paleogene Shahejie Formation in Liuzan area of Bohai Bay Basin was explored, and a two-dimensional model focusing on injection-production parameters was established to reveal the key factors affecting gas-liquid interface stability and displacement efficiency. The results show that: （1） During the transition from water flooding to gas flooding in high-dip angle reservoirs of northern Liuzan area, the top gas injection technology improves oil displacement efficiency by 20% approximately，controlled by the stable gas cap formed by gravity differentiation and the immiscible displacement mechanism dominated by it, while the improvement of oil displacement efficiency by direct gravity is relatively limited. （2） Appropriately increasing the injection-production ratio can enhance gas cap pressure and the ability of gas to penetrate micro-pores, thereby improving gas-liquid interface stability. （3） The equation for stable gas injection rate can effectively predict the optimal range of gas injection rate for gravity drive，and can analyze the development dynamics of gas injection in real time.
