摘　　要：针对冷41块在超稠油藏开发中存在严重底水锥进等一系列问题,在综合研究油藏地质特征的基础上,采用水平井钻井技术,通过精心设计、组织和施工,取得显著的开发效果。为提高超稠油藏储量动用程度,提供一条新的技术途径。同时为水平井钻井技术在类似油藏中的应用提供了有益的借鉴作用。A series of problems existed in Leng 41 block during the development of super heavy oil reservoir, such as serious bottom water coning and so on. On the basis of studying the geologic characteristics of the reservoir, horizontal drilling technology was used in development of Leng41 - Pingl2 well. With elaborate design, organizing and construction, remarkable development effect was obtained . This kind of technology can provide a new approach to improve the producing degree for the super heavy oil reservoir. At the same time, it also can provide helpful ref- erence for the similar reservoir.
