摘　　要：江苏油田S7块地质条件复杂,构造小、油层薄、渗透率低,在这样的油田钻水平井,采用几何导向钻井很难命中最佳地质目标,通过采用地质导向技术,取得了较好的效果。介绍了S7P1水平井应用随钻地层电阻率、自然伽马测井来指导井眼轨迹的实时调整和控制,并对该区块实施地质导向钻井提出了建议。S7 block in Jiangsu oilfield is characterized by complex geologic conditions, small structures, thin reservoirs and low permeability. When geometric steering technology is used to drill horizontal wells in this kind of oilfield, it is very difficult to penetrate the optimum geologic targets. Geosteering technology is used and the effects are good. Resistivity and gamma ray logging while drilling are used to guide the real time adjustment and control of well trajectory in S7P1 horizontal well. Proposals are presented for utilization of geosteering drilling technology in this block.
