摘要
通过分析渤海稠油油藏冷采测试数据,结合油藏工程理论公式及油藏数值模拟计算,确定渤海稠油油藏冷采测试黏度参数限值。在此基础上,利用油田冷采产能测试资料,评价热采产能,形成渤海稠油油藏热采产能评价方法。研究成果可应用于评价油田是否适合冷采测试和指导油藏合理产能配置,从而节省勘探成本、提升油田开发效益。
Due to the limitation of thermal production technology and cost in offshore oil fields,cold production test is often used to obtain production capacity of Bohai heavy oil reservoir in evaluation stage.By analyzing the cold production test data of Bohai heavy oil reservoir,combining reservoir engineering theory formula calculation and reservoir numerical simulation calculation,the technical limits for cold production test viscosity of Bohai heavy oil reservoir are determined.On this basis,the thermal production capacity of Bohai heavy oil reservoirs is evaluated using the cold production capacity test data of the oilfield,and a thermal production capacity evaluation method is developed.The research results can be used to judge whether the oilfield is suitable for cold production test and guide the reasonable production capacity allocation of the reservoir so as to save exploration cost and improve oilfield development benefit.
