摘要:
水平井地质导向有2个关键点，入窗点精确着陆和水平段地质导向。阐述了水平井地质录井导向技术要点，以金XXX井为例，利用现场实钻综合录井资料、LWD电性资料及水平井所钻地层及油气层录井表现特征，选择合适的标志层，精细对比地层，综合判断钻头与地层的钻遇情况，成功实现水平井地质导向。
There were two key points in horizontal well geosteering: precise landing in the window and geosteering in the horizontal sections. By taking Well Jin XXX as an example, the key points of geosteering logging in horizontal wells were introduced in detail. Based on the actual drilling logging data, LWD electrical data and logging characteristics of drilled formation and oil and gas reservoirs, the geosteering in horizontal wells has succeeded by choosing the suitable marker beds, fine stratigraphic correlation, and comprehensive identification of the drilled formation.
