摘要/Abstract

摘要： 油藏型储气库协同天然气驱油一体化建设是近年来兴起的重要方向，其通过重力分异、混相驱替及萃取抽提等作用，可在有效提高原油采收率的同时，形成大规模季节性调峰能力。以冀东油田PG2储气库为例，系统开展建库地质条件评价、盖层及断层密封性分析、储气库注采能力设计与库容参数优化等研究，论证该类油藏改建储气库的可行性。研究结果表明，目标区块储层厚度大、物性较好、流体性质优良，区域盖层发育稳定和封闭能力强，综合评价地质体动态密封承压上限达44.9 MPa，具备良好的建库地质基础；方案最终工作气量可达9.0×10⁸ m³以上，日调峰能力达到近0.1×10⁸ m³，预计提高原油采收率约20个百分点（较水驱开发），证实块状挥发性油藏改建储气库技术可行、经济有效，形成的相关技术方法可为同类油藏协同提高采收率与储气调峰提供重要借鉴。

Abstract: The integrated construction of oil reservoir-type gas storage coupled with natural gas flooding for enhanced oil recovery has emerged as a significant direction in recent years. Through mechanisms such as gravity segregation, miscible displacement, and extraction, this approach can effectively improve crude oil recovery while establishing large-scale seasonal peak-shaving capacity. Taking the PG2 Underground Gas Storage of Jidong Oilfield as an example, this paper systematically conducts geological condition evaluation for gas storage construction, sealing analysis of cap rocks and faults, design of injection-production capacity, and optimization of storage capacity parameters, thereby demonstrating the feasibility of converting such oil reservoirs into gas storage facilities. The results indicate that the target block features thick reservoirs, favorable physical properties, excellent fluid characteristics, and regionally stable cap rocks with strong sealing capability. The comprehensive evaluation shows that the dynamic sealing pressure limit of the geological body reaches 44.9 MPa, providing a solid geological foundation for gas storage construction. The proposed scheme achieves a working gas volume of over 9.0×10⁸ m³, a daily peak-shaving capacity of nearly 0.1×10⁸ m³, and an expected increase in crude oil recovery of approximately 20 percentage points compared to water flooding. These results confirm that converting blocky volatile oil reservoirs into gas storage is technically feasible, economically effective, and the associated methodologies can serve as an important reference for similar reservoirs aiming to simultaneously enhance oil recovery and provide gas storage peak-shaving services.

Key words: massive volatile oil reservoirs, underground gas storage rebuilt from oil reservoir, trap sealing property, storage capacity parameters, feasibility studies
