摘　　要：在详细分析超薄油藏水平井钻井难点的基础上,认为水平井井身剖面的优化设计除了应从钻井工艺和力学角度分析外,更需要从油藏地质条件出发进行考虑;阐明了地质因素诸如储层沉积类型、油层厚度、产层几何形态、储层非均质性等对水平井随钻井身轨迹的影响。从大庆油田实际出发,强调地质导向作用,提出了"精雕地质模型,把握地质导向,加强随钻监测,控制井眼轨迹"的技术措施与方法,研发了集地质模型预测、钻井轨迹控制、计算机软件决策为主要功能的监测系统,展现了良好的应用前景,对完善大庆油田水平井技术、提高油田开发水平具有实际意义。On the basis of a detailed analysis about the difficulty of horizontal well drilling in thin reservoir, the paper suggests that the optimization design of horizontal well bore profile needs to consider reservoir geological conditions besides consideration of well drilling technology and mechanics. The impact of geological factors such as sedimentation type, reservoir thickness, geometric shape of pay formation and reservoir heterogeneity on the horizontal well bore trajectory along drilling were established in this thesis. Considering the actuality of Daqing oilfield, the paper emphasized the role of geological direction and brought forward the technical measurement of carefully geological modeling, grasping geological direction, strengthening monitoring along drilling and well course controlling' . An integrated monitoring system was devised including geological forecast, drilling track controlling and computer software decision making. These techniques have a promising prospect and a practicalmeaning for horizontal well technology and oil field development improvement in Daqing.
