摘要： 从板块运动、水动力条件入手,对塔河油田奧陶系古岩溶地貌的形成机制进行了探讨,指出该区孔洞缝发育最有利的地带是溶蚀沟陡岸、凹岸及地势较高的缓坡带,其次是地势较高的残丘群,再其次是洼地周边地带、溶蚀洼地及斜坡带。指出本区古岩溶地貌形成的重要因素是以板块运动为动力,以隆起为背景,以断裂和水为条件,时间是关键,脚洞是大的孔洞发育带形成的基础。

Abstract: In view of plate movement and hydrodynamic conditions, a mechanism of forming ancient karst land-form of Ordovician in Tahe oilfield is discussed. It is pointed out that the most favorable developed zones of pores, caves and fractures are firstly the steep coast and concave coast of solution channel as well as gentle slope zone of higher relief; secondly the monadnocks of higher relief; finally the zones such as pothole surroundings, dissolution potholes and slope area. The important factors for forming ancient karst landform in Tahe area are powered as plate movement, back grounded as uplift，conditioned as faulting and water, of which the key is timing, while foot cave is the foundation of forming big cavity-developed zones.
