摘　　要：塔河油田奥陶系油藏是大型碳酸盐岩裂缝和岩溶缝洞型油藏。油藏的储渗空间主要为规模不同的溶洞、裂缝带、溶蚀孔隙和微裂缝。油藏开发实践证实,油藏呈现出多缝洞系统、多压力系统、多个渗流单元的特征。针对储集层复杂的特点,提出了利用动态信息分析油藏缝系统与洞系统之间连通性的研究思路和方法(包括油藏压力趋势分析法、井间生产干扰分析法、流体性质差异分析法、井间干扰试井法和示踪剂法等),并结合塔河油田实际资料,进行了流动单元初步划分和分析。The Ordovician reservoir in Tahe field is a large carbonate reservoir with fractures and caves.The reservoir pore spaces are various caves,fractures,solution pores and micro-fractures.The reservoir development practice confirmed that this reservoir is characterized by multi-fractures-caves,multi-pressure systems and multi-flow units.This paper proposes the analytical methods for using dynamic information to analyze connectivity between fracture and cave,including the reservoir pressure trend analysis,the interwell production interference analysis,the fluid property difference analysis,the interwell interference well test analysis and tracer testing analysis,etc.Also,combined with Tahe actual production data,the flow units are classified and analyzed preliminarily.
