摘　　要：AziTrak深方位电阻率边界探测工具是近年来水平井随钻实时跟踪中成功应用的探边仪器,对水平井优化井眼轨迹、评价油水关系复杂的油气藏以及薄油层开发起到了积极的作用。利用AziTrak深方位电阻率边界探测工具可以非常有效地给地质导向工程师提供直观的360°井筒图像,可以直接判断边界的距离和方向,工具具备单边探测和双边探测功能,因而对水平井优化井眼轨迹、提高油藏采收率的效果显著。针对陆丰油田开发中遇到的实际困难,利用该随钻工具最大限度保障了水平井地质导向的准确性,提高了水平井开发效益。AziTrak Deep Azimuthal Resistivity Boundary Detection Tool was successfully applied in real-time tracking in recent years, and played a positive role in optimizing well trajectory of horizontal wells, evaluating the complex relationship of oil and gas in hydrocarbon reservoirs and oil sheet development. AziTrak Deep Azimuthal Resistivity Boundary Detection Tool can effectively provide intuitive 360 ° wellbore image for geosteering engineers and directly determine the distance and direction of the border, and thus it has remarkable effects on optimizing well trajectory of horizontal wells and increasing oil recovery. According to the difficulties encountered in Lufeng Oilfield development, by the use of this LWD tool, the accuracy of the horizontal well geosteering is improved at the maximum extent and the effectiveness of horizontal wells is also increased.
