摘　　要：地震导向水平井方法是指以地震技术为主,建立钻井、测井、开发等多专业软件平台,实现多专业数据驱动、融合,真正实现"物钻测一体化"服务,对水平井有效钻进轨迹实施实时导向。具体说,即在钻头钻进过程中,在多专业软件平台上应用录井数据、LWD随钻数据与地震数据相结合,预测断层及岩性突变等地质异常,修正地质模型,动态调整钻头钻进轨迹,减少钻井风险,提高储层钻遇率。根据地震导向水平井在高陡复杂构造气藏及苏里格气田低渗透碎屑岩气藏的成功应用,形成了水平井导向技术流程和技术规范,充分展示地震技术在油气田开发中的应用前景。Centered on seismic technology,a multi-discipline software platform is built up in order to guide horizontal well drilling.This software platform integrates and analyzes multi-discipline data such as seismic,well drilling and logging,and enables to guide horizontal well drilling trajectory in real time.Specifically the software can predict geological anomalies,such as fault and lithological variation,revise geological model,and dynamically adjust drilling bit trajectory.It is very helpful for reducing drilling risks and increasing the reservoir drilling rate during the drilling process.This seismic centered multi-discipline software platform has successfully applied in a complex gas reservoir and a low-permeability clastic gas reservoir,which fully demonstrates the seismic prospect in oil-gas field development.On the other hand,the operation procedure and the technical standards of the technology are set up.
