摘　　要：靖边气田目前剩余储量多属于品质差、地质情况复杂的"三低"储量,利用水平井技术提高该类储量的采收率,可以达到深度挖潜的效果。针对靖边气田储层厚度薄、小幅度构造复杂的特点,开展小幅度构造精细描述,建立精细地质模型,并在此基础上进行水平井地质优化设计研究,有效地解决了薄储层和小幅度构造对水平井实施的影响,提高储层钻遇率和开发效率,取得了显著的经济效益,对同类气藏的水平井开发具有指导作用。At present, residual reserves of Jingbian gasfield are defined as 'three low' one with poor quality and complicated conditions of geology. To enhance the recovery, horizontal-well technology can be adopted. According to the properties of both thin-layer thickness and complex, low-amplitude structure, this paper carries on the fine description of low-amplitude structure, and then establishes a fine geological model and studies geological optimization design for horizontal well. Therefore, a negative impact of thin layer and low-amplitude structure on the operation of horizontal well has been solved effectively. Probability of penetration and productivity are increased and significant economic benefits are obtained. It provides some guidelines for horizontal-well development of similar gas reservoirs.
