摘　　要：针对评价阶段渤海稠油油藏产能评价研究中,冷采测试产能与流体性质矛盾问题,冷采测试油藏黏度技术界限问题,如何利用冷采测试资料配置热采产能的问题进行研究。通过研究,确定冷采测试产能与流体性质矛盾原因。通过统计渤海稠油油藏冷采测试数据,结合油藏工程理论公式计算和数值模拟方法确定稠油油藏冷采测试黏度技术界限。结合渤海稠油油藏热采开发规律,确定稠油油藏冷采测试产能与热采产能关系倍数,在此基础上形成了渤海稠油油藏产能评价方法。Aiming at the contradiction between cold production test productivity and fluid properties in Bohai heavy oil reservoir productivity evaluation at evaluation stage.Technical limit of reservoir viscosity testing in cold production.How to use cold production test data to allocate thermal production capacity is studied.Through the research,the reasons for the contradiction between cold production test productivity and fluid properties are determined.Based on the statistics of cold production test data of Bohai heavy oil reservoir,the technical limit of viscosity in cold production test of heavy oil reservoir is determined by combining reservoir engineering theory calculation and numerical simulation method.Based on the thermal production development law of Bohai heavy oil reservoir,the relation multiple of cold production test productivity and thermal production productivity of heavy oil reservoir is determined,and the productivity evaluation method of Bohai heavy oil reservoir is formed on this basis.
