一种新型的6.75英寸随钻测井（LWD）地球化学工具已研制成功，可用于复杂油藏的精确岩性、矿物学、井位选择和地质导向应用。该LWD工具利用脉冲中子发生器产生的俘获和非弹性伽马射线，实时提供地层元素和矿物浓度以及σ值和直接碳测量数据。

工具说明

总体设计。LWD工具的标称尺寸为6.75英寸。

A novel 6.75-in. logging-while-drilling (LWD) geochemical tool has been developed for accurate lithology, mineralogy, well-placement, and geosteering applications in complex reservoirs. This LWD tool uses capture and inelastic gamma rays induced by a pulsed-neutron generator to provide real-time formation elemental and mineralogical concentrations and sigma and direct carbon measurements.

Tool Description

General Design. The LWD tool is available in a 6.75-in. nominal size.
