斯伦贝谢油田服务公司研制的新型随钻测井系统基于标准的三组合测井服务平台,缩短了仪器与钻头的距离,提供了新的测量服务,例如Σ测量和元素俘获测量等。该系统实现了在井场对地层特性和钻井环境的完整复杂的数据解释,提高了仪器的操作时效,增加了穿透能力,增强了系统的稳定性,尤其是在仪器中利用中子发生器代替镅–铍源,消除了作业中的放射性源带来的危险。 New Drilling LWD system developed by Schlumberger Oilfield Services A standards-based three-component logging service platform shortens the instrument-to-bit distance and provides new measurement services such as Σ-measurement and elemental capture measurements. The system realizes the complete and complicated data interpretation of formation characteristics and drilling environment in the wellsite, improves the operation aging of the instrument, increases the penetrating ability and enhances the stability of the system. In particular, the use of a neutron generator Replace 镅 - beryllium source, eliminating the hazards of radioactive sources in operation.
