摘　　要：渤海油田部分老油田开发时间较长,随着开采的进行储层砂体平面和纵向非均质程度高、储层连通性较差、底水油藏储量比例大。为保证底水油藏的有效开发,在后期井网调整中以水平井作为开发的主要井型。本文通过H油田地质特点和钻井工程难点,利用水平井轨迹优化、着陆段钻井工具优选、水平段地质导向技术应用等手段,成功实施了小井眼侧钻水平井E15H1井,地质导向随钻实施效果较好,投产后产量高于配产20%。Old oilfield in Bohai oilfield has a long development time, with mining were reservoir sand body surface and high degree of vertical heterogeneity, reservoir connectivity is poor, the proportion of bottom water reservoirs large. Horizontal well is the main way of development. This article present geological features and drilling engineering difficulties in H oilfield, and with trajectory optimization, choosing of drilling tool for landing section, using of geosteering tools drilled E15H1 well. After putting into operation, the effect is better, the output is increased by 20 %.
