摘　　要：针对靖边气田马五1＋2碳酸盐岩储层水平井开发中面临的“侵蚀沟槽发育、主力储层厚度薄、小幅度构造变化快、储层非均质性强”等实施难点，综合应用三维地震技术、地质储层评价、技术经济分析以及气藏数值模拟等研究方法，建立了水平井井位优选、轨迹优化设计、现场地质导向与轨迹调整等水平井开发关键地质技术。使得完钻水平井有效储层钻遇率达到60％以上，单井产量达到了直井的3～5倍，实现了靖边气田水平井规模化应用。According to the developmental difficulties of horizontal well including that erosion groove is de- veloped,main reservoir is thin, the small amplitude structure changes quickly and lateral heterogeneity is strong in MaWUl＋2 carbonate reservoir of Jingbian Gasfield,integrated application of seismic technique,res- ervoir evaluation,technical and economic analysis and numerical simulation of gas reservoir and other re- search methods,established a series of horizontal well development key geological technology, such as hori- zontal well trajectory optimization,optimization design and geosteering and trajectory adjustment. Through the application of the technology, horizontal wells effective reservoir drilling rate has achieved more than 60%, the single well production reached 3-5 times of vertical well,and the Jingbian gas field horizontal well realized large scale applications.
