摘　　要：VisiTrak超深电阻率探测工具是贝克休斯公司自主研发的一种地层界面反演工具。该工具主要借助安装在旋转导向BHA上的浅、深、超深探测感应器进行井筒360°全方位电阻率的探测,再结合仪器自带的半自动化反演算法,获取井眼轨迹与地层界面垂向之间的空间关系,从而实现对井筒周围地质情况的全面描述。该技术在南海东部陆丰凹陷古近系油藏水平井应用中,能够有效指导水平段轨迹在穿越断层时的调整方向,保证水平段砂岩钻遇率,保证轨迹始终处于储层甜点钻进,该技术在南海东部水平井轨迹甜点控制方面应用效果良好。VisiTrak ultra-deep resistivity detection tools are Baker Hughes Company independent research and development of a stratigraphic inversion tool,this tool is mainly by means of installed on the rotary steering BHA in shallow,deep and ultra-deep detection sensors,wellbore 360o full resistivity detection,coupled with the instrument's own semi-automatic inversion algorithm,the contact relationship between the wellbore trajectory and the axial direction of the formation interface is obtained to achieve a comprehensive description of the geological conditions around the wellbore.In the application of horizontal wells in Paleogene reservoirs in Lufeng Sag in the eastern South China Sea,this technology can effectively guide the adjustment direction of horizontal section trajectory when crossing faults,ensure the drilling rate of horizontal section sandstone,and ensure that the trajectory is always drilled in the sweet spot of the reservoir.The application effect of this technology is good in the control of horizontal well trajectory sweet spot in the eastern South China Sea.
