地质导向录井在水平井施工中关键技术

摘要

地质导向录井的核心任务就是根据随钻过程中的LWD仪器测得伽马、电阻率、密度、孔隙度等地层参数,结合综合录井中的岩性、物性以及含油气资料来进行 "预测"和"导向"的过程.文中着重对着陆地质导向录井的地层对比和预测技术,水平段地质导向录井的油层边界识别技术进行了探讨,在水平井地质导向录井施工中具有一定的指导作用.%The core tasks of geosteering logging are forecasting and guiding based on the formation parameters measured by LWD, which include drilling gamma,resistivity,density and porosity along with lithology,physical properties and oil and gas resources in comprehensive logging. The stratigraphic correlation and prediction in landing geosteering logging and reservoir boundary recognition in horizontal section of geosteering logging are discussed in this paper for reference.
