摘　　要：目前水平井技术在国内外油气田开发中得到了广泛应用,尤其是在直井难于开发的边际超深薄层油藏中能产生很高的效益。同垂直井相比,水平井在油藏中增加的井筒裸露面积使油井获得更高的生产能力,使得水平井可能以经济流量进行生产,采用水平井生产还增强了生产压差调控主动性,对抑制边底水的快速锥进有积极作用,更有利于非均质油藏内部产液结构的优化调整。介绍了塔里木油田超深超薄砂岩油藏双台阶水平井在钻井和开发生产中的相关技术,以期对类似油藏的开发提供参考。At present, the horizontal well technology is applyed widely in the development of oil-gas field both in China and abroad, and make greater benefit in boundary deepmost thin-bed reservoir which isn′t easy to be exploited by vertical well. To compare with vertical well, horizontal well which has larger wellbore bare area in reservoir could get higher production capacity. At the same time, using horizontal well technology can enhance the controlling go-aheadism of draw down pressure, and it can not only restrain side-bottom water coning, but also can optimize producing-liquid structure inside non-homogeneous reservoir. This paper introduced some correlative technologies of double-step horizontal well which is used in super-deep and super-thin sandstone reservoir in Tarim oilfield. This could offer some reference for analogy reservoir development.
