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。

Abstract

According to the developmental difficulties of horizontal well including that erosion groove is developed,main reservoir is thin,the small amplitude structure changes quickly and lateral heterogeneity is strong in Mawu1+2 carbonate reservoir of Jingbian Gasfield,integrated application of seismic technique,reservoir evaluation,technical and economic analysis and numerical simulation of gas reservoir and other research methods,established a series of horizontal well development key geological technology,such as horizontal 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.
