摘　　要：渤海浅层河流相油田存在储层薄、砂体相变快的特征,在水平井着陆过程中,由于目的层构造深度及砂体平面展布均存在很大的不确定性,同时受常规边界探测工具和常用预测方法能力的限制,水平井着陆难度很大。为了提高薄层水平井着陆的成功率引入超深边界探测法,以其远距离探测地层信息的能力在水平井着陆过程中辅助对目的层深度进行预判,从而实现主动导向调整。渤海K油田4-1区块内A井的成功应用证实了该方法的可靠性,在油藏地质条件复杂的河流相储层中该方法可以准确预测目的层位置,提高了水平井着陆成功率。The shallow fluvial facies oil fields in Bohai Sea are characterized by thin reservoirs and rapid sand body facies change.During the landing process of horizontal wells,there are great uncertainties in the structural depth of target layers and the plane distribution of sand bodies,at the same time,the landing of horizontal well is very difficult because of the limitation of conventional boundary detection tools and common prediction methods.In order to improve the landing success rate of thin⁃layer horizontal wells,the ultra⁃deep boundary detection geological guidance method is introduced,and the depth of target layer is predicted by the ability of long⁃distance detection of formation information during horizontal well landing,to achieve proactive orientation adjustment.The successful application of A well in Bohai K Oilfield 4⁃1 zones proves this method can accurately predict the target layer position in fluvial facies reservoir with complex geologic conditions and improve the landing success rate of horizontal well.
