摘　　要：柴达木盆地台南气田是全国罕见的第四系生物成因气田,储层岩性以泥质粉砂岩、粉砂岩为主,其地层疏松、成岩胶结差等特征给钻井带来了不少技术难题,尤其给水平井钻井带来了很大的挑战。从导向前准备,施工过程中采取的主要措施、遇到的问题以及应用效果分析等方面,详细地叙述了水平井导向技术在台H5-1井的应用情况,为疏松砂岩地层水平井地质导向提供了有益的借鉴。Tainan gasfield of Qaidam Basin is a Quaternary biogenetic gasfield.The reservoir is composed of mud siltstone,siltstone and mud-bearing siltstone.Its properties of loose formation,poor diagenetic cementation bring about many technical problems during drilling,especially in horizontal-well drilling.According to some aspects of the design,pre-drilling preparation,main adopted treatment,problems and application analysis during the operation process,this paper illustrates the application of geosteering technique of horizontal well to Well Tai H5-1,which provides a useful reference for horizontal-well drilling with loose sandstone.
