摘　　要：为降低成本,达到对地质靶精确控制的目的,中原油田结合老油区已有的地质资料,采用MWD随钻GAMMA测量技术,配合气测录井的甲烷C1监测数据,通过计算调整井眼轨迹控制,综合判定油层着陆,走向倾角变化,提高了水平井眼的油层穿透率,有效地达到了利用地质导向施工水平井的目的。结合卫360-平1井的具体施工过程,介绍了C1+GAMMA地质导向技术在中原油田薄油层水平井施工中的应用经验,为今后油田水平井开发提供了技术参考。To reduce costs and realize precise control of the geological target, the penetration coefficient of horizontal hole is improved by integrating the geological data of old oil pools of Zhongyuan Oilfield, using the MWD-GAMMA technology and the C1 methane monitoring data for gas logging, adjusting trajectory control through calculation, and determining reservoir landing and strikedip change. The purpose of geosteering drilling of horizontal wells is fulfilled. Combined with the operation of Wei360-H1 well, the application of the C1＋GAMMA geosteering drilling technology to horizontal wells in thin reservoirs in Zhongyuan Oilfield is discussed in this paper, providing technological reference for the development of horizontal wells in oilfields in the future.
