综合方法确定地层水盐度

本文提供了基于两种方法研究的工作流程来估计地层水盐度,提高测井作业期间快速决策的饱和度评估质量。

在完整的论文中,测试了两种方法来实现地层水盐度的测量。首先,使用先进光谱工具进行的新型干重氯 (DWCL) 测量来估计设备研究深度处的地层盐度。第二种方法在地层测试仪工具中使用新的井下感应电阻率电池。氯测量以及流线感应电阻率测量有助于提高饱和度评估的质量,以便在测井作业期间快速做出决策并加速评估研究,而不是等待实验室结果。

Integrated Approach Determines Formation-Water Salinity

This paper provides a work flow based on research in two methodologies to estimate formation-water salinity, enhancing the quality of saturation evaluation for quick decision-making during logging operations.

In the complete paper, two methodologies are tested to achieve measurement of formation-water salinity. First, a novel dry-weight chlorine (DWCL) measurement from an advanced spectroscopy tool is used to estimate the formation salinity at the depth of investigation of the device. The second methodology uses a new downhole induction resistivity cell in the formation-tester tool. The chlorine measurement, along with the flowline-induction-resistivity measurement, helps enhance the quality of saturation evaluation for quick decision making during logging operations and acceleration of evaluation studies instead of waiting on laboratory results.

Chlorine Work Flow

The ability to quantify chlorine concentration can help derive formation salinity as a continuous curve.
