摘　　要：塔河油田为岩溶缝洞型碳酸盐岩油藏,储集体类型以溶洞为主,非均质性极强。为提高油藏勘探开发效果,在大量岩芯、测井以及地震的基础上,结合井间连通性、生产动态资料对岩溶发育的控制因素进行了研究,地质构造演化不仅控制了岩溶分布,且决定了岩溶发育的环境;裂缝是岩溶发育的关键因素,构造裂缝为岩溶发育提供了通道,而非构造裂缝则加速了岩溶作用;水动力条件则控制了塔河油田地表以及地下岩溶发育的格局。Tahe oilfield is a fractured-vuggy carbonate reservoir, whose reservoirs are mainly composed of vast karst caves, and the heterogeneity is very serious. In order to improve the effect of exploration and development of Tahe oilfield, based on a comprehensive research on rock core, logging and seismic,combined with inter well connectivity, production dynamic data multidisciplinary approach, a comprehensive study is used in the karstification development in this process, the distribution of karst controlled by the geological and structural evolution, also determined the environment of karst development; and fracture was the key factor which controlled the karst development, structural fractures provided channels for karst development, moreover, non-structural fractures accelerated development of karst; and hydrodynamic condition had controlled the development pattern of surface and subsurface of Tahe oilfield.
